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, for this will make the biggest difference in the success of your plants’ yield. Marijuana 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 will have an effect on your cannabis plants.
Outdoor marijuana seeds:
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.
Best seeds for your climate
All marijuana plants are not alike. Depending on the grower’s preferences and the surrounding climate, marijuana has evolved differently in different geographic locations.
For instance, tropical locations often have marijuana plants with very small leaves but many flowers. Middle Eastern and Central Asian strains, on the other hand, usually 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 which strain 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 greater leaf sizes.
Indica, sativa and ruderalis
Indica’s tend to be short and wide, have greener colors, and have rounder leaves with patterns that look like marble. The high is heavy and centered on the body.
The indica variety comes from a number of different places including Kashmir, Morocco, Afghanistan, and Tibet.
These locales are well-known for their tradition of producing hash and kif, two THC-filled byproducts of the cannabis plant. Indica plants tend to be shorter (around 3 to 6 feet tall) and contain broad leaves, dense foliage, and a dark bluish green hue that can appear purple sometimes.
During the maturation process, indica plants can start to turn even more purple. They will also produce thick, dense buds. The characteristic “skunky” aroma and taste of indica is a defining property of its smoke. When smoking, you tend to feel the relaxing and almost hypnotic effects in your body more than your brain.
Sativa’s tend to be taller, thinner, and have pointier leaves without patterns. The high is energetic and centered on the brain.
Sativas are a tropical variety originating out of places like Mexico, Colombia, and Thailand. Despite the fact that these plants come from warmer climes, they have proven to be adaptable to colder temperatures. They are tall, slender plants that can reach up to between 8 and 12 feet. Unlike the indica variety, sativas have thinner leaves and a light green coloration.
As the buds mature, they start to turn red, but if the climate is colder, they may start to turn purple. Other sativa strains may have a slight “golden” or yellow hue. Spicy, fruity, and sweet are all ways to describe the smell and taste of sativa plants. The high is very cerebral and lively.
Ruderalis plants tend to be small and are used in clothing, rope manufacturing but also for their breeding potential to produce autoflowering marijuana plants.
Ruderalis is typically cultivated in the northern Himalayas and in a few of the southern former Soviet states. It grows in a scant, weedy pattern and is typically never cultivated for use as a psychoactive drug.
Hemp cultivation used to be prevalent in places like the mid-western United States, and some extant ruderalis populations can be found in that area. Wild ruderalis also appears in great quantities in places like Latvia, Belarus, Lithuania, and nearby nations. Because humans rarely cultivate these plants, they have lost the traits that make them desirable to humans.
Although ruderalis has a relatively low THC content by comparison to both sativa and indica, they do possess some desirable properties. Ruderalis is high in cannabidiol (a less potent cannabinoid than THC), and some medical marijuana patients grow these varieties.
But the real draw of ruderalis for some breeders is that the plants can be autoflowering and also highly resistant to pest problems and disease. Indica strains are commonly crossed with ruderalis strains to produce THC-filled plants that are autoflowering. These plants also tend to have more resistance to environmental pressures and shorter height.
Hybrid marijuana strains
As the term suggests, a hybrid occurs when you cross a sativa with an indica or an indica with a sativa. Virtually every strain is a cross-breed between an Indica and a Sativa for the best of both highs.
Any crossbred plant will contain a certain amount of indica characteristics and a certain amount sativa characteristics. Every strain has its own unique mix of medicinal characteristics.
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.
One of the most important aspects of choosing a marijuana seed is how likely that seed is to thrive in the climate and environment that you intend to grow it in. Sativas generally take longer to mature than pure indicas, but, with cloning and breeding, you can make crosses between the two that mature in suitable time periods.
Of course, it’s more vital to take into account the climate when buying your marijuana seeds. What kind of weather do you expect during the growing season?

It’s also always a good idea to look at 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, but northern locations will have to prepare differently.
If the ground is still frozen at the start of spring or if early winter frosts are an issue, then it’s important to have a strain that grows in a shorter amount of time (usually indicas). You can start later in spring and harvest earlier in the fall so that the cold temperatures do not affect the yield or potency.
Best seeds for hot climates
So here are our best outdoor marijuana seeds to grow in Southern Latitudes with warmer climates. If you live in Southern Europe, southern parts of the United States and Australia you should grow one of these strains:
The Blueberry marijuana plant offers a very fruity blueberry taste and euphoric high that will last quite a while.

This high yielding Strawberry Kush is also a fast flowering plant with glistening buds that do not need cold temperatures to turn color. Can also grow in colder weather like Washington State, Netherlands and Britain. More about Strawberry
My personal favorites
The one question I get the most is “Which marijuana seeds are the best for yield and simplicity in my region?” 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, then these are what I’d choose:
Indica – White Widow
Everybody needs to cultivate and smoke a little white widow. It is one of the most popular strains in Amsterdam coffee shops and it’s loved by indoor growers, too. It is easy to grow and produces an extensive yield and a fantastic high. There’s nothing better than white widow!
White widow is particularly well-known for the glaze of white trichomes that cover its exterior. These trichomes are extremely high in THC and white widow benefits from a high potency. The strain is highly relaxing and has also been used as an appetite booster. Although it is an indica-dominant strain, it still maintains a large amount of sativa characteristics.
Mood enhancement and increased activity can also be experienced when smoking white widow. The strain is usually compact and rises to medium heights. The plant’s buds only produce a small amount of amber-colored hairs, but the amount of crystals caked on to the buds is legendary. The strain is also resistant to mold and well-suited for colder locales. Buy white widow marijuana seeds
Sativa – Super Silver Haze
Everything about white widow could be said about super silver haze as well. 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.
The strain is a perfect blend of notable strains including Northern Lights, Haze, and Skunk. The scent and taste of super silver haze is like no other. It packs a fragrant, skunky, and spicy punch that has improved moods and relaxed the body for decades.
You have the combination of a relaxed stone and a stimulated high that proves to be a perfect mix every time. As long as you provide the plant’s roots with plenty of room to grow, you should end up with outstanding yields. Buy Super Silver Haze marijuana seeds
Ruderalis – Super Skunk feminized autoflower
As I’ve noted previously, the only real benefit of autoflowering seeds is the fast flowering time. Marijuana generally starts to flower when the seasons change and the light cycle diminishes, but autoflowering plants will start blooming in only a few weeks.
They are always rather small and do not produce the highest quality bud, but you can harvest them in no time! When the season starts, I always germinate 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 with the quick flowering time of cannabis ruderalis. The growth patterns and beautiful bud structure are consistent and quite aesthetic to look at.
Although short and small, the plant produces substantial colas and plump, THC-riddled calyxes. The high is immediate and potent, but it is followed quickly by an almost somnolent, long-lasting body buzz. Buy Super Skunk autoflower marijuana seeds
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 normally 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 a tropical type of marijuana strain. The same goes for other similar climates, such as Louisiana, Texas, and anywhere along the Gulf Coast. Other growers in these locations may decide to go with a Sativa strain, which tends to be hardier and has plenty of variety in structure and color.
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 great.
If you’re an experienced smoker of weed, you are already well aware that a high can vary quite a bit. Some get 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. You should choose your marijuana seeds accordingly; no one wants a bad high, do they?
So how do you get the good high and avoid the bad? It’s quite simple, really: just make sure to get the seeds from the marijuana that you like best, and make sure you’re curing the bud in the correct way once you have harvested it.
It is surprisingly easy to acquire seeds since many growers don’t want to use them themselves. There are often a large quantity of seeds left over. Plenty of companies exist online, where they post photos displaying what the final result of the seeds should look like.
Because working online always comes with potential risks, make sure you are cautious and know whether the company is legitimate or not. If you buy marijuana seeds from my webshop I guarantee delivery, germination and high quality genetics.
All in all, it’s extremely important to have marijuana plants with good genes. No matter what strain you choose, bad genetics are bad genetics. Be sure you’ve done the proper research before buying anything.
Seasonal changes in mind
Choosing a strain of marijuana that works for your climate and grow location is not as simple as it sounds. You should focus on how successful that strain has been in its native climate, and what kind of success that will translate into within your own climate.
Savita strains generally take a longer time to mature than other strains that are Indica dominant. To acquire the perfect strain for you, you should find strains that are a mix of two different types, Indica combined with Sativa.
Before making any decisions, take a close look at your climate. What will the weather be like throughout the growing season? Find out what the average temperatures are, especially at the end of the fall and start of spring seasons.
Many growers who live in northern, colder locations have some trouble at the beginning of the season: they often have to deal with the ground remaining frozen at the beginning of spring, or else an early winter frost at the end of the fall season. These factors can reduce the potency and yield of your marijuana plants.
These factors mean that marijuana growers who live in colder climates often choose strains that have a shorter growing time. This will let them avoid the first frost so they can remove their plants well before it comes.
Growers in southern or tropical regions do not have to contend with the same problems. Instead, they will find that the sunlight during all parts of the growing season is consistently strong.
Cannabis plants are especially responsive to how much and what kind of light they receive. When a mature cannabis plant receives less than 12 hours of light per day, for instance, it then will utilize all of its energy for flowering instead of growing. This can be used to the grower’s advantage.
Some growers intentionally restrict the amount of light with the purpose of speeding 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, thus “convincing” the plant that fall weather is coming and it needs to begin flowering.
It is sometimes wise to start flowering even earlier, depending on where you live. If you live in a place that is prone to an early frost, early flowering can come in handy.
If you have grown plants of any kind before, you will know that a frost hitting your plants can cause them to have a lower potency and yield. Another method that growers in northern climates use is planting multiple strains of marijuana seeds, which all flower at different times.
You can see when your plant is mature enough for a change in sunlight exposure time by paying attention to its branching. In the third or fourth week of growth, you should be able to see the secondary branching starting to begin. This is when the plants are mature enough to have the light manipulated accordingly.
Regional differences in strains
There are a wide number of marijuana strains, all native to different locations. Each strain has its own set of unique qualities that need to be taken into consideration before you choose the strain that is best for you.
Plenty of other strains and combinations of strains exist, and the possibilities are endless. Many of the most renowned strains that have even received awards in Amsterdam or California are combinations of different strains.
If you happen to come across seeds with these superior genes, make sure you have a complete understanding of the conditions and climate in which it was originally grown. You would not want to waste the opportunity with experimental growing, potentially resulting in a failed attempt.
Having a proper grasp of what your climate is like is the most important near the start and finish of your cannabis plant’s life. Marijuana plants are the most fragile when they are seedlings because they have not yet had the chance to build up a resistance to outdoor changes.
The more mature a marijuana plant is, the stronger and thicker their stems are, meaning they are better able to protect the inside from any external changes. Therefore, if you live in a location that includes frosts at the beginning of your spring season (marijuana’s growing season), then you might want to think about starting out your cannabis growing inside of a greenhouse or other controlled setting indoors. You can then transplant them at another time when they have had the chance to develop a resilience against outdoor weather effects.
Let’s fast forward to the other side of a cannabis plant’s life: the fall. Depending on where you live, your climate might get frost even before fall begins.

Although mature plants can take a certain amount of cold and frost, if they are exposed to cold or frost multiple times in a row, they can lose taste as well as potency. And, worse still, if you don’t harvest them right away then the entire crop could be completely lost.
So how do you ensure that this doesn’t happen? If you’re a first-time grower in this type of climate, it would be a good idea to keep an eye on the sun, as well as get some advice from nurseries and resources that spring perennial growers use.
Spring perennials include crops such as tomatoes and corn, and help you find out when the frost often happens, as well as when the best time to harvest your plants is. Of course, after a few harvest seasons, you will have an excellent understanding of timing. Keep in mind that you have more leniency in the fall than in the spring, as you will be working with more mature plants.
If you are someone living and growing in a climate that does not have any of these major freezes, you could potentially grow your plants throughout the entire year. Assuming the soil, water, and light supplies are all good enough, marijuana plants that are grown in this type of climate are generally shorter with many buds.
Although the winter sun is still not as strong as the summer sun, it will be enough to stimulate plants to grow. When spring rolls around you can trim your cannabis plants. This will help achieve a natural stage of growth for the normal time to harvest (fall).
Choosing a strain that fits your climate is perhaps the most crucial first step in growing successful cannabis plants outdoors. If you choose a strain that thrives in a different climate 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 a fine yield, as well as nice seeds for further planting. Choose wisely and check all my marijuana seeds for the best genetics.
