Best outdoor marijuana seeds for your climate

When deciding what kind of cannabis seeds to buy, you need to take a number of factors into account.

First and foremost, you should get acquainted with your own climate.

This alone will make the biggest difference in the success of your plants’ yield.

Marijuana outdoor seed varieties come in different shapes and sizes.

These variations are from their successful growth in a very specific type of climate.

Light intensity and length of exposure, temperature, altitude, and seasonal changes all influence your cannabis plants.

Having a thorough understanding of your climate is most important at the start and finish of your cannabis plant’s life.

This is because marijuana plants are the most fragile when they are seedlings.

They have not yet had the chance to build up a resistance to outdoor changes.

It’s your job to find out which strain is perfect for your particular climate, but I’ll help you with that. 

In my online seed shop, you can select marijuana seeds by type, climate, yield, and much more.

The outdoor marijuana grow cycle

First, let’s review how a marijuana plant grows.

The marijuana plant lifecycle begins as a seedling.

During this time, it is very sensitive to its environment, because its roots are not firmly set into the ground.

Seedlings must be protected from frost when growing outdoors.

In some places, a late Spring frost means it’s a good idea to use pre-grown seedlings or clones. You can also use seeds and create your own ‘starts’ indoors or inside a greenhouse.

Once your plants are strong enough, and the chance of frost has passed, you can transplant them to their outdoor location.

During the summer, the plants enter the vegetative cycle.

This is when cannabis plants grow big – as long as they maintain the proper temperature and have plenty of water.

The Fall is when marijuana plants typically begin their flowering cycle.

Flowering plants aren’t as sensitive to their environment as seedlings, but you still need to protect them from frost.

A heavy frost at this time can interfere with bud production and reduce the potency of your harvest.

Growing outdoors doesn’t have to be incredibly difficult.

By understanding your climate, you can pick the best seeds for growing outdoors.

How to choose the best marijuana seeds

So how do you choose the right strain for your growing preferences and climate?

If you know where certain marijuana strains are typically grown, you can get a good idea of what type of strain would work well in your own climate.

People who want to grow their plants in Florida, for instance, should choose tropical weed strains.

The same goes for other similar climates, such as Louisiana, Texas, and anywhere along the Gulf Coast.

Weather is not the only factor that is important to consider. You also need to look at any other differences between your seasonal changes and the marijuana strain’s native seasons.

For instance, a strain that originated in Hawaii thrives in its long Hawaiian growing season.

This means it might not reach its full potential in your own climate, as it most likely has a shorter growing season.

You would still end up with a yield that is perfectly smokable and will get you high, but the size of the plant will be smaller, so your yield will not be as high.

What about the specific strain? If you’re an experienced weed smoker, you’ve probably tried a wide variety of strains.

You know that some will put you into a happy or dreamy state right away, while others might take longer and result in a sleepier state.

You probably also know that not all highs give you a good feeling; sometimes headaches, sore throats, or paranoia can be the type of high you feel.

Use that knowledge to choose your perfect marijuana seeds. No one wants a bad high, do they?

You’ll also want to get good quality seeds. Seeds that won’t germinate are worthless.

Seeds that germinate into unhealthy plants are also useless. No matter what strain you choose, bad genetics are bad genetics. You can learn how to germinate cannabis seeds with our guide.

Of course, you don’t have to buy your seeds. You can always find seeds from a marijuana plant.

However, most commercial weed is very careful to remove their seeds nowadays. Should you decide to buy marijuana seeds online, make sure you find a reputable source.

In my webshop, I guarantee delivery, germination, and high-quality genetics.

Selecting the best strain

Choosing to grow a specific strain because you like the effects, does not mean it will grow well outdoors where you live.

If you are researching strains for your region, the first thing to understand is that there are many types of marijuana plants.

Due to grower’s preferences and the surrounding climate, marijuana has evolved differently in different geographic locations.

Marijuana strain
Cannabis strain

For instance, tropical locations often have Sativa marijuana plants with very small leaves but many flowers.

Middle Eastern and Central Asian strains, on the other hand, usually have Indica plants, which have larger leaves (both in breadth and length) and denser buds.

Differences in leaf size reflect differences in sunlight strength and consistency. Larger leaves have evolved in locations with weaker light, in order to absorb as much sunlight as possible.

The greater the leaf size, the more sunlight they can be exposed to at one point in time.

These differences may seem superficial at first, but in fact, they can make a huge difference when you are deciding what to plant.

If you live in a climate where there is not much sunlight, or it is particularly weak, then you will want to choose a strain that has a tendency for bigger leaf sizes.

Here’s a bit more about the different types of cannabis plants.

The best climate for Cannabis indica

Cannabis indica can grow in a variety of climates. It features broad leaves that capture a lot of the sun.

This subspecies originated in places such as Kashmir, Morocco, Afghanistan, and Tibet.

These areas are well known for hash and kief, potent cannabis byproducts.

Indica plants tend to be short and wide, making them better suited to handle colder temperatures.

Unfortunately, the densely packed leaves do not do well with high humidity and heavy rainfall.

When growing during the summer, this is problematic since Indica strains are not the best strains to grow in high heat.

Thankfully, they won’t need to be in the heat for long.

This form of cannabis flowers quickly – some can flower in as little as 7 weeks.

This means it can be grown in cooler areas that tend to have shorter summers.

They also make an ideal second harvest once the summer heats calm down in areas with enough sunlight and a late frost.

Cannabis Indica plants can produce remarkable colors depending on their environment.

Some maintain a vibrant green color, while others can turn a dark bluish-green that can appear purple.

The leaves feature patterns that look like marble; the buds are dense and give off a skunky aroma.

The best climate for Cannabis sativa

Sativas, on the other hand, are a tropical variety originating out of places like Mexico, Colombia, and Thailand.

Many tropical weed strains are pure Sativas or Sativa dominant hybrids.

The plants tend to be taller and thinner, with thin, pointy pattern-less leaves.

Sativa plants love the sun and can grow up to 12 feet tall. In general, the buds are airier than indicas.

This fact alone makes Sativa genetics the best strains for hot humid climate conditions.

Sativas are also fairly versatile. They can thrive in hot, rainy environments, such as tropical rainforests, but also adapt to colder temperatures.

The one downside to this subspecies is its long flowering cycle.

In tropical regions, there are no cold seasons and plenty of sunlight.

Because of that, these plants evolved into taking their time – sometimes as long as 14 weeks.

For some places, the sun isn’t around long enough for these plants to fully mature.

Cannabis Sativa plants tend to have light green or golden leaves.

Mature leaves may turn shades of red (or purple is growing in a colder region).

The buds give off a spicy, fruity, or sweet aroma.

The best climate for Cannabis ruderalis

There’s a third type of cannabis, but it isn’t typically consumed as marijuana. Ruderalis plants are used in clothing, rope manufacturing, and crossbreeding to produce autoflowering plants. Of all the cannabis subspecies, Ruderalis survives in most conditions. They are known for their toughness. These short, small plants grow in a scant, weedy pattern and are highly resistant to pest problems and disease. These traits are owed to the natural conditions from which wild ruderalis plants originated:

Wild Cannabis ruderalis is known to grow in:

  • Russia
  • Latvia
  • Belarus
  • Lithuania
  • Other Eastern Europe nations

Although not interesting for direct consumption. Their autoflowering offspring are great to grow in colder climates and harsher conditions—all thanks to the Cannabis ruderalis traits.

Hybrid marijuana strains

A hybrid combines a Sativa and an Indica to create a strain with specific desired qualities.

Hybrids are designed for easy growing, therapeutic benefits, increased potency, or unique flavor and taste.

If you want to gauge how much of a Sativa or Indica your hybrid plant is, then just take a look at the fingers on the fan leaves.

If the fingers are wider than normal, then you have a “mostly indica” plant.

If the fingers are thinner than a normal leaf, then you’ve got a “mostly sativa” plant.

Sativas generally take longer to mature than Indicas, but with cloning and breeding, many Sativa dominant strains can grow much faster.

Remember to think about your unique situation when selecting seeds.

For example, before you search for “the best strains to grow in the northeast,” start by asking yourself this simple question:

“What kind of weather do you expect during the growing season?”

Consider the average temperatures in your area at the start of Spring and Fall.

Tropical and southern locales will usually provide plenty of light and warmth for marijuana plants. Northern locations will have to prepare differently. Read our cannabis temperature tutorial to learn more.

If the ground is still frozen at the start of Spring or if early winter frosts are an issue, it’s vital to have a strain that grows in a shorter amount of time.

This is usually something that is indica dominant.

You can start later in Spring and harvest earlier in the Fall so that the cold temperatures do not affect the yield or potency.

How to grow weed outside in the winter

The cannabis growing season goes from Spring to early Fall, but creative growers can grow year-round, even outdoors.

When growing weed outdoors in winter, you’ll need to do a little extra work.

First of all, there’s the lack of sunlight. This is solved by using autoflowering varieties.

These types of marijuana seeds do not rely on a specific amount of sunlight to begin their flowering cycle.

That means that even in winter, the plants can bloom and produce resin-filled flowers.

Growing weed outdoors in winter also has an additional drawback – cold temperatures.

Growing cannabis plants outdoors in winter
Growing marijuana plants in winter

Unless you are growing near the equator, your plants will be exposed to frost, which can ruin your harvest.

Growers can get around this challenge by growing in heat- controlled greenhouses or building temporary structures with heaters.

If you are in a climate (or can create one) that does not experience major freezes, growing weed outdoors in winter is a definite possibility.

However, you will not have the same result. The winter sun is not as strong as a summer sun.

Even if the soil, water, and light supplies are all good enough, the plants will be shorter and produce less potent buds.

The good news is, in certain areas, the winter sun is enough to stimulate plant growth.

Once Spring rolls around, your plants should be ready for harvest.

The best seeds for hot climates

Many marijuana strains originated near the equator, so it is no surprise that plenty of strains can thrive in hot climates.

However, some of the best outdoor strains for most growers thrive in a Mediterranean climate like you’d find in Southern Europe, many of the southern parts of the United States and Australia.

If you are looking for the best strains to grow in high heat, you must first consider whether that heat also includes humidity.

Warm-Wet Coastal Climate

A Mediterranean climate rarely experiences extreme shifts in temperature, which makes it the ideal growing environment.

However, very few places can provide this stability for growing cannabis plants.

Instead, many growers, especially those in an area like Florida or Australia, must seek out tropical weed strains that can survive extreme heat and high humidity.

Here’s one of the best strains for hot humid climate conditions.

Amnesia Haze

Amnesia Haze Marijuana Strain
Amnesia Haze

The Amnesia high is mostly in the head. It has a flowery and hazy smoke, and it is ideal for a strong yet mellow high.

The dark lime green buds are steady and densely covered with crystals. This classic Amnesia marijuana seed strain has spawned dozens of crosses.

Like many tropical weed strains, it grows best in Southern states like Texas, or countries like New Zealand or Colombia. More on Amnesia

Hot-dry southern climate

Excessive humidity can be challenging for marijuana plants, but high heat also makes it difficult.

When temperatures remain high, while humidity stays low, most plants will not have enough moisture to survive.

However, some strains are more up for the challenge than others. Unlike tropical weed strains, these hot dry climate strains can survive on less water.

Here’s one of the best strains to grow in high heat:

Sour Diesel

Sour Diesel Marijuana Strain
Sour Diesel

Sour Diesel is a mood-boosting Sativa dominant strain with relaxing effects. This tall plant loves the sun and dislikes wet climates.

Unfortunately, it takes a long time to flower; northern hemispheres can harvest around early November. Sour Diesel is one of the best because of its high yield.

Although it will take a while, you could be rewarded with as much as 25 ounces per plant.

This strain grows best in sunny desert climates such as Nevada, New Mexico, Southern California, and the Australian outback. More on Sour Diesel.

The best seeds for cold climates

For the most part, cannabis plants prefer warm temperatures; however, some marijuana strains thrive in northern latitudes.

These strains can survive the occasional cold spell. They may also do well in warmer climates (as autoflowers) when growing weed outdoors in winter.

Here are some of the best strains to grow in the Northeast and Northwest United States, Western Canada and Northern Europe:  

Northern Lights

Northern Lights Strain
Northern Lights

Northern Lights is a classic strain that is deeply relaxing while also putting you in a good mood.

This indica dominant strain typically harvests around mid-October and prefers a climate that isn’t too hot or too cold.

Northern Lights plants have an average height and are very resistant to disease. This strain can thrive in Western Europe and the Pacific Northwest. More on Northern Lights.

My personal favorites

The one question I get the most is, “Which marijuana seeds are the best for yield and easy to grow where I live?”

Each strain maintains its own unique characteristics, growth processes, and flavors.

But, if you asked me to choose my favorite indica-dominant, sativa-dominant, and ruderalis-dominant strain, here’s what I’d choose:

Indica – Super Skunk

Super Skunk Seeds
Super Skunk

Super Skunk is one of my favorites because of its well-balanced high, and flexible growing environment.

This Indica dominant hybrid qualifies as one of the hot dry climate strains and one of the cold climate strains. It’s super easy to grow and is very resistant to disease.

Super Skunk plants are average height with light green leaves that are covered in brown hairs. The buds are dense but easy to maintain.

Flowering times will depend on the environment, but it is typically ready in late September. However, it may take as long as late October.

Although it is Indica-dominant, Super Skunk is still a good daytime strain. It’s known for boosting moods and appetite, and it can stimulate creativity while simultaneously relaxing the body.  

Super Skunk’s yields are impressive as well.  You can harvest up to 21 ounces from a single plant! Buy Super Skunk marijuana seeds

Everything about White Widow could be said about Super Silver Haze. It’s simple to grow and produces outstanding yields and fantastic highs.

I’m always amazed at how fast Super Silver Haze grows and how much quality bud the plants can make. It’s perfect for humid areas with short growing seasons.

Super Silver Haze is a blend of notable strains that include Northern Lights, Haze, and Skunk.

The scent and taste pack a fragrant, skunky, and spicy punch. The aroma alone can improve moods and relax the body.

There isn’t much stress with this plant.  As long as you provide the roots with plenty of room to grow, you should end up with excellent yields. Buy Super Silver Haze marijuana seeds

Ruderalis – Super Skunk feminized autoflower

Super Skunk Auto Strain
Super Skunk

As I’ve noted previously, autoflowering seeds are bred from Ruderalis plants – giving them their fast flowering time.

Marijuana generally starts to flower when the seasons change, and the cannabis light schedule diminishes.

Autoflowering plants, on the other hand, start blooming in only a few weeks.

The problem with many autoflowers is that the yields are small, and they don’t always produce the highest quality bud.

However, certain strains, such as the autoflowers in my store, continue to produce a good quality product even when bred with ruderalis.

When the season starts, I like to grow a few Super Skunk autoflowers so I can enjoy a smoke while the standard seeds grow.

This super skunk strain provides all the benefits of the world-renowned super skunk genes combined with the quick flowering time of cannabis ruderalis.

You can plant this strain after the final frost in any region and still have enough time to flower.

It may not be one of the best strains to grow in the Northeast, but if you keep an eye out for mold, it can work. Buy Super Skunk autoflower marijuana seeds

Seasonal considerations

Selecting your ideal marijuana strains starts by identifying the correct seeds for your climate, but it’s not the only consideration.

A strain does well in its native region, not just due to the environment. The length of the seasons is also essential.

This is very noticeable with Savita strains, which generally take a longer time to mature than Indica strains.

Choose a cannabis strain that works for your climate
Choose a strain that works for your climate

Since many growers do not live anywhere near cannabis’ native lands, a hybrid mixture of the two will likely be a lot easier to grow.

Most of the award-winning strains are also hybrids, giving yet another reason to grow them.

When choosing strains, think about the weather throughout the entire growing season.

Find out the average temperatures, especially at the end of the Fall and start of spring seasons. This essential step can help you identify the best outdoor strains for your area.

Many growers who live in northern, colder locations have some trouble at the beginning of the season.

This is when they might experience frozen grounds when they should be planting their seeds.

At the end of the season, they must also watch for an early winter frost. The end of the season tends to be more forgiving since the plants are near maturity.   

Growing marijuana outdoors
Plants are finally getting some winter sun

Marijuana growers who live in colder climates should choose strains with a shorter growing time.

That way, they can avoid the first frost and remove their plants well before it comes.

If you have grown plants of any kind, you already know that a freeze can lower your potency and yield. One exposure to frost is typically okay, but multiple times can ruin your plants.

If you are growing someplace prone to an early fall frost, consider using autoflowering plants or triggering early flowering

How do you ensure you aren’t surprised by frost? If you’re a first-time grower in your climate, it would be a good idea to keep an eye on the sun.

You can also get some advice on spring perennials from nurseries and other resources.

Spring perennials include crops such as tomatoes and corn.

By paying attention to when these plants grow, you can figure out when frost often happens, as well as the best time to harvest your plants.

Of course, after a few harvest seasons, you will have an excellent understanding of timing.

Growers in southern or tropical regions do not have the same problems.

Instead, the sunlight is consistently strong, and the weather remains warm during all parts of the growing season.

This allows the plant to continue growing until they start receiving less than 12 hours of light per day. When they do, they know to stop growing and begin flowering.

Sativas in southern climates can grow for a long time.

For a quicker harvest, some growers intentionally restrict the amount of light to speed up the flowering process.

They might move potted cannabis plants, or else cover them up with a cloth. These intentional light limitations can create the same effect as natural light changes.

You are basically “convincing” the plant that Fall weather is coming, and it needs to begin flowering. This, of course, isn’t necessary with autoflowering plants.

You can see when your plant is mature enough for a change in sunlight exposure by paying attention to its branching.

In the third or fourth week of growth, you should see the secondary branching starting to begin.

This is a sign of mature plants that are ready for light manipulation.

Regional growing tips

Are you looking for a shortcut to picking the best strain for outdoor cannabis growing?

Well, your specific region can be a useful guide.

Although they aren’t precise and do not cover every scenario, areas within the same climate region tend to have similar temperatures and humidity.

Here’s how to best grow marijuana outdoors in these United States climate regions:

Marijuana outdoor growing tips according to the region chart
Cannabis growing tips according to the region chart


The Northwest includes the Cascade Mountain Range that separates it into two distinct climates.

West of the mountains, there is constant rain and overcast, which leads to a lack of sunshine.

This makes it difficult to grow marijuana due to the increased risk of mold during most of the growing season.

However, the nutrient-rich soil makes using a greenhouse worth the extra effort.

East of the Cascade Mountains, the climate has near-desert conditions with plenty of sunshine.

It is excellent for outdoors growing. Autoflowers or indica dominant strains are best due to a shortened growing season.

The soil isn’t as nutrient-dense as it is west of the mountains, but there’s enough rain to keep your plants happy.


The Southwest is known for its incredibly hot daytime temperatures and warm nighttime weather.

There isn’t much rain, and the soil typically lacks nutrients.

Outdoor growers should plan on purchasing soil or nutrients. Sativa dominant strains are best for growers in this area.


The Midwest is full of unpredictable weather and extreme temperatures.

Summers are typically very hot, and they sometimes can be very wet.

Add the occasional early winter or spring frost, and you also must deal with a very short growing season.

Midwest growers should watch for mold near the end of the flowering cycle due to possibly wet, cold conditions.

When growing outdoors in the Midwest, you’ll want to use nutrients or purchase soil.

At one point, this area was very fertile, but years of heavy farming has depleted much of the region of its nutrients.

Because of the potential cold temperatures during the flowering stage, indica dominant or autoflowering strains are best for growing outdoors in this region.


Short summersand highhumidity are the trademarks of the Northeast.

Surprisingly, this is perfectly fine for cannabis plants.

The native soil has plenty of nutrients, but it may be very rocky or filled with clay.

Because of the humidity, you’ll want to avoid densely packed indica genetics.

Instead, the best strains to grow in this region are fast finishing or auto-flowering Sativas dominant hybrids.


High humidity and temperatures mean you should avoid growing indica genetics outdoors.

Indica plants will struggle with the high temperatures, and the dense buds will likely mold.

The soil in this area tends to be rich. Most Sativa plants will have no trouble growing here.


The mountain areas include multiple regions; however, they all share the qualities of being difficult to grow outdoors.

Not only will you experience extreme temperatures, but the soil is often infertile.

If you are growing outdoors, choose valleys for the best soil.

Plant on the south side of a mountain for the most sun exposure.

Due to a short growing season, the best outdoor strains for most mountain areas are quick flowering.

Choosing a strain that fits your climate is perhaps the most crucial first step in growing successful cannabis plants outdoors.

If you select a strain that thrives in an environment different from your own, you will be sorely disappointed in the results.

If, on the other hand, you choose a strain that matches your climate well and care for your plants properly, you will be rewarded with exceptional yield.

You may even have some lovely seeds for future planting.

To get started, choose wisely and start with my marijuana seeds for the best genetics.

FAQ about cannabis seeds and climate

Is it possible to grow cannabis in cold weather?

Marijuana plants can be damaged in cold temperatures. The main advantage of cool weather is simply the ability of deter pests. Plants grown outdoors require daylight temperatures that are at least in the mid-60s (18C); otherwise their growth will begin to slow dramatically until it essentially stops. Temperatures in the evenings must be in the 40’s at least (5C), otherwise tissue loss can occur. You can have a potential problem whenever the weather drops below 45F (7C)

Are there any issues with growing cannabis in humid weather?

Marijuana plants love humidity, but too much of it can cause problems.

What can I do to protect my cannabis plants in hot climates?

If you are growing in hot weather, it is essential that you do not let your growing medium dry out. Marijuana plants drink a lot of water when it’s hot. If they don’t have anything to drink, they’re going to dry out by the end of the day.

  1. Hey been around Cannabis all my lfe but this is the first time ive Actually grown any on my own im from southwest vA so any tips will help ot alot

  2. I like reading about growing in a cold climate like Canada I think you guys are number one But your no shipping to Canada sucks Can’t find a workaround

  3. Your table “Here’s how to best grow marijuana outdoors in these United States climate regions:” doesn’t include the Mid-atlantic states (New Jersey, Pennsylvania, Delaware and Maryland…. feeling neglected 😉

  4. Have ordered seeds from ILGM 4 times always received seeds n orderly fashion had a few that didn’t germinate received replacement seeds n short order great company good people recommend them to any one any time they will treat you right

  5. Found selfsown were in ausie bad frosts but growing came off crappy tangarinedream given to us lastyear i tostout a bit of a suprise to find is this unusual

  6. Just discovered this site. I need some advice about seeds. I live south of Sacramento in the San Joaquin Valley. Lots of 90+ degree weather days. Late frost. Very little rain.
    I would appreciate any and all advice. I am a disabled senior on budget. I am a daily user MS and several other health issues. I use a heavy Indica for pain and sleep.. Forbidden Fruit is a favorite.
    I have had good luck with a hybrid strain called. Sunflower.
    Too expensive to buy from dispensaries.
    Thank you.

  7. Another tip for outdoor growing, especially in the SW is to buy sponges, cut them up and add them closely around the root under soil. The sponges hold water and provide water longer.

  8. So far, only 1 out of 5 seeds have sprouted. I’m an experienced grower. In fact, I have two clones growing right now from a white widow. I want some variety however, so I’ll just keep trying. Just wanted to let you know that 1 out of 5 is very poor.

  9. The pic of the early frost was snow not frost snow falls already frozen and you can just shack it off your plant and go on with your day frost is when wet moist air Settles down on your plant then freezes on your plant looks like little ice crystals stuck to your plant you can’t shack it off the sun has to melt it off much worse then a little snow I live in Vermont it’s part of growing here but love the article keep the knowledge coming.

  10. Living in the south east having 4 different strands Bruce banner, California kush, Bergmans gold leaf, gorilla glue, I am middle of SC and Georgia State line. Will all do good in this zone Augusta Go —– Aiken SC. between thies 2 states

  13. Bought the same black berry kush as last year. They were dark green lush short and fat with nice buds. This Year they are tall and slender a softer green and have a strong smell. Last year they smelled awesome. So what could be the problem, wrong seeds shipped ?? I grew them the same. Will let you no what goes on in the next few months. Hope They do good and yield is good.

  14. Just wanted to share first yr experience. I purchased GG4 seeds last yr. All 5 popped and trans planted. Plants grew well till July. Here in Wva we had above normal rainfall. Had small mold issue. Addressed issue as Instructed. Plants made to 9 ft and approximately 8oz per. Ty for all assistance from ilgm and other blogger for great first experience. and trying a different strain this yr. banana kush.

  15. Just a Querie on amnesia haze and locations. If I remember right you stated Texas , New Zealand and Columbia.. I live in South Australia and know New Zealand is cold and wintery. Just confused how NZ marries into this hot climate of strains. . Greatful for your info and mean no malice by this comment. Cheers mate. Aussie Dave

  16. Have you heard anything about daylilies having an inhibiting effect on marijuana? I installed a bed of dailies adjacent to my pot growing area and have had my pot plants not perform as well as anticipated. They just don’t grow like they should during veg. They finish nicely with lots of crystals and dense buds, but they’ve only been getting to 2-2.5 feet across the full summer. I put in some c-99 and original amnesia, both of which should get fairly large. They made it to 2.5 feet and had no significant branching. I had Been getting power plant clones from a grower buddy of mine, (they would get to 7 + feet) but have lost track of him at this point and have resorted to dispensaries for clones and seeds from a reputable company. With little to write home about. Could this be due to close proximity to the dailies? Any insight would be appreciated!

    • Scott,

      I would not think that Daylillies caused you any harm. I would suggest that you brought in russet mites or nematodes in the clones you bought. russet mites are so small you will need a scope 50x to see them. Inexpensive scopes are available for approx. 50 bucks on Amazon. I also suggest you join our support forum where we all could share information related to your grow methods and what if anything has changed, causing you to have issues. Happy growing 🙂 ILGM support forum:

  17. … wanted to try something different … ordered five Jack Herer … one of the five geminated, but didn’t sprout … first problem with your seeds … in the past have had very good luck with white widow and AK47 ….these were all auto flowers … can’t have tall plants, nosy neighbors …..

  18. hi I live in the pacific northwest, i sm curious to know whic strains would be best for my location, also i am growing only indoors! thank you

  19. What strains will you say is the best for someone in the tropical wet zone? I’m a lover of plants which lean more on the sativa side in terms of high. I will however like a your top three suggestions thanks.

    Thanks for the wealth of information shared on here.. great stuff..

  20. I would like to try Autos, in UK & Almeria in Spain. Any direction would be good as an alternative to indoor, I looked at Auto-flowering years ago, but it was not the best back then, now, I’m told that advances have been made and the idea is so confirmed as worthwhile?

    • Eddie,

      I am sorry to say I do not understand your question. Autos are of better quality and potency over the past few years. There are more strains available than years ago. I really like the feminized seeds. Great quality and yield. 🙂

  21. Looking to help out a disabled buddy of mine in Las Vegas. It is legal to grow 6 plants per household. I need a good seed for him to use. I will be supervising his efforts from NC. Thanks.

    • Try the Blue dream, White Widow, or the “Fruity Pack” Fp contains Blueberry, Strawberry Kush, and Pineapple Haze. All are excellent and will provide different medicinal efects.

  22. I live in northern Canada next to Alaska. A drier climate (no mould issues) with lots of sunlight but cooler temperatures and a short season. I’d like an outdoor autoflower that would do well here with as much of a Sativa high as possible. What would you recommend? Cheers!

    • Sunbear,

      You want a fast growing short term plant that is Sativa dominant. That is opposite of what Sativa does. Sativa always takes longer to finish than Indica. Blueberry, and Kush plants would finish fast. Blueberry is more Indica but, Indica finish much sooner than Sativa. As always; I suggest you go in the seed shop and research the auto flowers and find the perfect choice for you.

  23. i have only 2 question!
    1) Temperature is before of june, day time always sunny 25°-30°C, night time is 10°-18°C. Where i live.
    its 1200-1500 M. altitude its maybe high, so after seedling 2 or 3 weeks veg. İ wanna grow on mountain, is it possible to grow sir, i can not safe them with anything like metarials, only i can make super soil and watering thats all. i want to harvest before of september.
    2) Doyou have ship to turkey?
    And how do we have a ship chooise.

    • Jonathan,

      I believe if you choose a Kush or Blueberry type strain you could grow it in that time frame. I cannot guarantee that the night temperatures won’t be too cold. All I can tell you is to give it a shot and hope for the best.

      As far a shipping to Turkey; I suggest you look in the shop and read the shipping policy regarding orders to Turkey.

  24. Hello there.
    How about Ecuador, in the middle of the world? 12/12. I’ve started to grow a sativa, a hybrid (60s-40i) and a rudelaris. My climate is wet.
    Would you please give me some tips? Does your book talk about this region.

    Have a wonderful new year.

    • Jacebo,

      I suggest growing any strain of “Haze”. For grow advice; I usggest you join our forum at where we are set up to help you grow successfully. 🙂

  25. Best seeds for North Central KY? I understand seed purchasing laws in this state. Most seeds you sell (feminized) seem to be preferred indoor growth. If I decide to plant, I may germinate as early as 4/20 indoors, plant into “peat pots” and expand into larger “peat pots” as they demand. We have potential for hail and nasty weather here but plants will be protected in bad conditions. I can put off germination but also prefer high yielding but short plants (about 6 feet as tallest). I have grown 8 ft. plants. What is your suggestion for strain?

    • Dallas,

      I think you would like our “Fruity Pack”, any of the Kush Strains, White widow. Robers’s Gold Leaf yields well.

      Happy growing

  26. Thanks for my growing experience, very great help, along with YouTube. I am growing 4 healthy plants, out doors, Southern California, my 2 auto floweres did great early season, already harvested, this company is legit, I plan to buy more seeds soon, 7 plants out of 15 seeds, was bummed at first, but like I said, I have four trees soon to harvest in October, or when the crystals tell me different,

  27. Also I’d like to point out I’d prefer quality to quantity so I’d like for you to recommend me a potent strain that would do well during winter here. Thanks once again!

  28. Afternoon! do you ship to Portugal?And if you do, what strain on auto would you recommend I use outdoors during winter?(Winter is not very harsh around here, less light than summer days of course, but not even close to snowing or anything)
    (Sry for possible mistakes in my English :P)

    Best regards!

  29. Hi Robert, and thanks for all the information you give, want to know if i got this wright
    white widow is a sure thing in hot humid weather. or what do you suggest
    FYI i live in Saudi Arabia in the eastern region and it gets up to 130 F ( 46 ) in summer and its very humid , and also the law here is very strict when it comes to Hash or Weed , and to be honest with you i am a bit worried if i order that i will be caught when its delivered , that’s if it ever passes customs, i don’t know how you will be sending it and how well it can be hidden
    what is your advice and ill order ASAP if you think ill be OK 🙂
    once again thanks and take care

  30. I live in S.Florida, and I have always grown Mexican Oaxacan Colts I brought back 27 years ago. I order different several outdoor strains, yet I am concerned that the sun/humidity is too much for some. Please inform me if I am making a mistake. I started with blueberry auto, pineapple auto, strawberry auto.

    • Brent,

      In hot humid areas with long summers and even longer grow seasons; One might consider Sativa dominant hybrids. In our ILGM seed bank, we have an Amnesia Haze, and a Super Silver Haze. I think you would do well with those type strains.

      Indica. Blueberry, Afghan, Kush; Do better indoors because of their shorter finish time. This is also due to the fact that the Hindu Kush, Afghan region is Mountains and short summers and lower temperatures.

      Come see us at the forum.

  31. I would like to know what are the ideal seeds for climates from 5 ° C to 20 ° C as the south of Brazil

  32. Excellent information thank you . My wife and I have been fighting breast cancer for 4 yrs and your grow bible has been a lot of help it’s been hard to afford the correct strain because of all the side effects from chemo. Thanks

  33. Hi,Fellow smokers,I live in Western Australia.During the Summer months November/April, the weather can get very humid and hot,any ideas or Info how to improve things, I got a small bubble ponic set up with a 250 watt h.p.s. light.I’M 68 years old and had my first smoke in Jamacia 1970.On my 21st Birthday. Never looked back.Stay High. Regards Walt.

    • Walt,

      Well, I don’t know what to tell you. This would take a prolonged interaction. why don’t you join us at and @latewood when you get there. WE have many fellows from Australia, and friendly members and staff that could shed some light on your issues. See you there. lw

    • Hello Walt!
      How many plants are you growing under that 250w HPS?? I would highly recommend increasing that to at least 400-600w if you grow more than one or two plants. I personally have 12 babies under 2000w HPS with a few LED’s hanging above the main canopy,as well as 4 T5 fixures for bottom lighting(not necessary,call it overkill if you will lol). But as you increase the wattage, in turn comes higher temps and high humidity. A dehumidifyer might work out for ya if you’re having mold issues. The key is to get the temps right around 70 degrees Farenheight, while keeping your RH(relative humidity) right around 55-60%. This is especially true if you grow Sativa strains,but durban poison seems to be pretty resiliant against mold/fungi as well as spider mites. They don’t like it for whatever reason. If you’ve ever smoked girl scout cookies, I think you’d like durban poison a lot seeing as how it’s one of the key ingredients.

    • Did you find the right seed for Northern Wisconsin Granger? I’m in that part of the country too. Was wondering what you decided on and how it went..

  34. What strains work best for the South African region? We get a lot of sun here especially our summers but the rains do damage to our plants in this season. For the hot season with sporadic rains that can be a week long followed by a scorching hot sun that can go on for weeks, what strains can u suggest? High yield strain would be a bonus. Thanks

    • durban poison, congo red, congo black. all these african sativas. grow well in the climate you mentioned. the soil in south africa generally has a red dust tinge due to its composition. these strains do very well in this type of soil.

    • Gail,

      We are sorry for the loss of your plants due to mold. Something is wrong with the environment that you are growing in. It is hard to do grow support in the blog area of our website. I invite you to join our support forum and you can use the guidance of our many knowledgeable growers and staff experts in order to grow successfully.

      I advise you to fill out a support ticket with all the info from your grow and methods you used. From there we can figure out what caused an environment that would create mold. See you there. 🙂 (click “forum” in top right corner of page)

  35. This llgm is off the chain, strong plants, its chilly at nights but the cold weather favorites mentioned really can take some extremes. Just get some!

  36. Still have a plant, white widow from April 26th just starting to bud. Quite a long period for an auto but it looks lovely! Can’t wait till its done. Looks like its going to be one liter size colas. Wow what’s up? Ilgmygag

  37. Any Indica would do. Look in the seed bank and choose an Indica that fits your needs.

    Things to look for. Higher % of Indica dominance. Shortest finish time

  38. I’m in central coastal CA. Have warm Summers, but Fall coastal fog, and rains start sometimes in Sept. need the best indica based mold resistant, high THC suggestions. Thanks

    • No replies Cuz this article sucks. I am in OR. Best indica I think this year are god bud, sweet god, hashplant…White Russian I here is popular in southern Oregon.

    • Hi Joel, Like Latewood said, All the strains available in the ILGM seed shop are great for growing almost anywhere. It is up to you to use the information on the website and plan out a grow that suits your environment. We are always here help you out at our ILGM forums. Just adjust the plan to fit your seasonal traits.

      • Bs, this article was horrible. From grammatical errors to misinformation. In Oregon 80% of hybrids won’t work unless you have a greenhouse and sup light. Oregon williamette valley requires fast finishing non dense cola varieties. Og, haze…wont do well in a normal fall.

  39. All the strains available in the ILGM seed shop are great for growing almost anywhere. 🙂

    It is up to you to read over the descriptions and plan out a grow that suits your environment. We are always willing to help you out at our ILGM forums, too.

    As long as you plant to get the plants started after frost, and before dead heat of summer, or Fall (too cold) I realize that your seasons may not match ours but, You just adjust the plan to fit your seasonal traits.

  40. […] This is why people a few years along will have better outcomes with their harvest. They often are choosing their best cannabis plants out of a single strain, so they take those seeds for the following season’s crop. They have a better understanding of the plant it came from, and, therefore, can also improve their own care of the same type of plant. Read the article Best Outdoor Marijuana Seeds […]

  41. Hi just wanted to say that I had a similar experience with two of my orders that never made it. Claire was very nice and asked me to wait for a period of time to see if it showed up. These folks at this site are great. M. Cicchino

    • I’ve been growing ILGM white widow autos outdoors in Vermont for 3 years. Can’t put seedlings out until end of May due to late frost. The only problem I’ve noted is the buds can start to mold. I put them in a portable greenhouse when flowering starts to protect from rain & humidity, and inspect them carefully every day, trimming out mold as needed. Harvest is around mid-September, about the time of the first frost. I have been pleased with the results.

  42. would you tell me the name of a good stran for indeana would like a low grower and a auto would you ples romend

    • Hi!, I guess Indiana have humid climates. I would suggest you plant strains that finishes early so you can avoid mold formation and other humidity problems. Try Bubble Gum strain.

      • Good to know. I am growing my first plants here in Northern Wisconsin.. hey are looking great but nervous about the cool nights .. This has been a real learning experience and I am enjoying it greatly… Next year I will choose The White Widow and the OG KUSH as you suggested. My daughter { In Washington State} sent me a few “Big Foot” seeds. Looking forward to trying them but will be more prepared next year. Thanks again for the suggestions.

  43. If anyone ever doubts that this company will get you your seeds, have no doubts.. after several attempts, seizures and letters I indeed received my seeds. Emails were sent back and forth, at one point, I had lost hope and asked for a refund, but to my surprise, the seeds showed up in a unique stealth package. I have never had a company work so hard to do what they promise. The seeds I started all took so far. Thanks for giving medical users a good deal, good products and excellent service.
