Weed growing supplies

Weed thrives anywhere there’s soil and light. However, you will need the skills and supplies to grow the best weed indoors. 

These weed growing supplies can range from the lights you use to the grow tents that house your weed.

It may sound expensive at first, but there are ways you can cut costs, like building your own grow tent.

What you shouldn’t compromise on are cannabis seeds. To get the best yields indoors, you will need high-yielding plants, which you can only get from growing weed strains with good genetics.

10 Marijuana growing supplies for high yields indoors

Marijuana seeds or clones

Depending on your preference, you can grow weed from seeds or clones.  Both have their advantages and disadvantages.

With clones, you can grow identical plants that share the exact same traits as the source plant. 

A source plant (sometimes called “mother plant”) refers to any weed plant that you take cuttings from to produce clones.

The advantage of growing clones is that you can take a high-yielding and vigorous plant and replicate it over and over. 

Since they’re identical, you won’t accidentally be growing a male plant in your indoor garden. 

The drawback to growing from clones is that you sacrifice plant symmetry since clones come from branches that do not grow evenly, unlike the main stalk.

With cannabis seeds, you produce new individual plants, which is advantageous since clones inherit everything from their source plant, including pests and diseases

With plants grown from seeds, you won’t have this problem. 

In addition, germinating seeds is easier than getting cuttings to root – especially if you choose good genetics.

You can source your cannabis seeds by either getting some from a seasoned grower you know or from a seed bank. 

While there’s nothing wrong with getting from a close friend of yours, purchasing your own seeds gives you more options and a better idea of what to expect in terms of quality, time, and yield.

Grow lights

Grow lights are one of the primary growing equipment you need to cultivate weed indoors. 

The ones that work best for weed are LEDs, HIDs, and CFLs. Lights are an important part of your pot growing accessories because the more light you give to your plants, the higher your overall yield will be once you harvest.

However, light can also affect your plants in other ways that aren’t desirable, such as burning them due to intense and close exposure to your grow lights. 

This could lead to light-stress-induced foxtailing, which can ruin your harvest– another reason you need to know how to choose the right grow lights for your setup and where to place them.

To avoid overstressing your plants, you must consider the following factors: color, intensity, duration, and distance. 

Color isn’t as important as the other three factors, but it does affect how vigorously your plants grow. 

Cannabis in their vegetative phase tends to grow faster under cool light, while during their flowering stage, they prefer warm light.

Intensity and duration go hand-in-hand with each other. Exposing your weed to intense light can oversaturate them and cause light burn. 

Meanwhile, keeping your plants under 24 hours of light will prevent them from producing any buds, which is only possible during ‘lights-off’ periods.

Lastly, there’s distance, which varies depending on the type of grow lights you use.

CFLs are perfect for compact setups since they can be placed inches away from the plant without burning or over-saturating them. 

You need a specific distance between your plants and the lights with LEDs.

Grow mediums

You’ll need something to grow your plants in, making grow mediums vital weed growing equipment.  

A growing medium can come in various forms, such as soil, vermiculite, coco coir, and perlite.

Growing marijuana in Soil

The different growing mediums can categorize into two main types, soil, and soilless mediums. 

Using soil is the traditional way of growing cannabis and involves mixing it with compost

This growing medium abounds with nutrients that weed needs, but it can also be a home for diseases and pests that can infect and harm your plants.

Some growers grow their weed in soilless mediums such as coco coir, perlite, and vermiculite (or a combination of the three). 

The problem with soilless growing is that the medium doesn’t contain any nutrients for your plants to absorb; you need to apply the nutrients directly via a hydroponics setup.

For this reason, soilless growing setups such as hydroponics and aquaponics are a lot harder compared to growing weed traditionally in soil

In contrast to soil, you need to understand how to construct your hydroponics setup and create a schedule for when your plants need to be fed. 

This is a lot more involved than purchasing the necessary pot growing supplies. 

Another example of a difficult growing style is aeroponics. It doesn’t use any growing medium and leaves the roots out in the open. 

Growers apply nutrients by spraying or misting the plant’s roots with a nutrient-rich aerosolized solution.

Grow nutrients

Plant nutrients should be one of the weed growing supplies you always have. 

While it’s true that cannabis can grow under any conditions, you will need to feed your weed plants the macro and micronutrients to help with their growth. 

The macronutrients you need are nitrogen, phosphorus, and potassium. At the same time, the micronutrients are calcium, magnesium, sulfur, manganese, and boron.

Two types of fertilizers can provide your plants with the necessary nutrients they need – they include organic and synthetic fertilizers. 

Animal waste, mineral sources, and compost naturally produce organic fertilizers.

Typically you need to prepare organic fertilizers before applying them to your soil. This can mean treating it, mixing it with other raw materials, or composting it.

The tedious process of preparing organic fertilizer isn’t for everyone, which is why some growers use synthetic fertilizers. 

This fertilizer provides the exact amount of macro and micronutrients for each stage in your cannabis life cycle. 

It’s made even more efficient by being immediately available for your plants to absorb once you apply it.

The only drawback of synthetic fertilizers is the feeding schedule you must maintain to avoid underfeeding or overfeeding your plants. 

Regarding feeding, some of the more difficult weed strains tend to be more nutrient-hungry than others. 

It’s best to stick to easy-growing strains if you plan to cut costs by reducing the number of nutrients you buy.

Weed pots and buckets

If you’re using soil as the medium for your cannabis plants, having grow pots becomes part of your weed growing supplies. 

This is because you will need a container to hold the soil mix where you plan to grow your weed. 

Marijuana grow pots

Pots are even essential outdoor growing supplies since they reduce the harmful pests and diseases exposed to your weed.

When it comes to grow pots, you have plenty of options, including terracotta, ceramic, and grow bags. 

However, for indoor setups, the best ones are plastic, fabric, and air pots. Plastic is the most common pot in an indoor growers supply.  

They’re inexpensive and easy to move around. Although a little more expensive, fabric pots are a superior alternative to plastic ones. 

They have better air circulation, which helps prevent the roots of your cannabis from suffocating. 

On the note of plant roots, air pots are the best pot you can use for yourself if you want to prevent rootbounding.

For those with a hydroponic setup or planning to build hydroponics for their plants, you will need a bucket to hold the solution housing your roots. 

You only need one bucket or reservoir to hold the solution since your plants would be planted in net pots that hang over the solution.

Other than the net pots, you will need an air pump and airstone to keep the solution oxygenated. 

This helps prevent the roots of your plants from drowning/suffocating. 


Proper ventilation is one of few must-haves for grow tents and other indoor setups

It prevents stagnant air by circulating it, ensuring a steady supply of Co2 for your plants to absorb and use for photosynthesis which, in turn, will create glucose that your cannabis uses to fuel their growth.

Proper ventilation for weed

Ventilation is also vital for plant respiration, a process where they absorb oxygen through their stomata to combine it with glucose to create adenosine triphosphate (ATP). This energy fuels their growth and development.

Preventing stagnant air also has the added benefit of reducing the chance of mold appearing on your plants and keeping the humidity level in your grow room stable.

Consider the different fan options before purchasing ventilation tools for growing weed. 

  • Oscillating fans are like plastic grow pots. They’re common and inexpensive. They work to keep your grow room well-ventilated and cool by providing a breeze for your plants which can also help strengthen their branches.
  • Inline fans are ideal for installing a proper ventilation system in your grow room because you can use them to push air in or out of your indoor setup.
  • Exhaust fans and intake fans work in the same vein. The only difference is that they’re specialized. Exhaust fans pull old air out of your grow room, while intake fans draw new air into your grow room.
  • Booster fans, as the name suggests, is a fan that accelerates the airflow in your ventilation system.  They don’t do much to introduce new air and remove old air; they only make the process much faster.


Temperature is important for plants’ health. It influences most processes, such as photosynthesis, transpiration, and respiration. 

It can also affect the growth of your cannabis buds by slowing them down. This is why thermometers are some of the best grow equipment for any setup. 


Getting the ideal temperature for your marijuana starts with knowing what to measure. Plan to check soil, room, and water temperature. 

These three things can affect the general health of your cannabis plants, depending on their temperature.

Soil temperature, specifically root zone temperature, is vital for your cannabis if you want your weed plants to effectively absorb nutrients and water from the substrate they’re planted in. 

The ideal temperature for soil is around 70-78°F (21-25°C), which is also the ideal room temperature you need to maintain in your indoor setup.

Water temperature is measured in two scenarios: 

when you’re using water to feed your plants and when you’re growing weed hydroponically—the ideal temperature for water when feeding plants is 73°F (23°C). 

Any higher than 77°F can result in delayed plant growth, and any lower than 59°F will cause the roots to stop growing and absorb nutrients, leading to deficiencies.

When growing weed hydroponically, you must keep the temperature at around 64°F.

Also read “Ideal temperature for marijuana plants

This will allow your young plants to grow out their roots without absorbing too many nutrients in the solution. 

You need to prevent your plants from absorbing too many nutrients to prevent nutrient burn. 

Once your plants have sufficiently grown and taken root, you can raise the temperature to 73°F so your plants can absorb more nutrients.

PPM testing tools

PPM testing tools are a part of any indoor or outdoor growing supplies. But what does PPM mean, and why is it important? 

How To Measure PH And PPM For Your Marijuana Grow
PPM for your marijuana grow

PPM is an abbreviation for parts per million, a unit of measurement that calculates the number of chemicals per unit volume of water. 

Total dissolved solids (TDS) are the same thing; it measures milligrams of chemicals per liter of water (mg/L).

You need PPM testing tools because they tell you the number of nutrients and other chemicals in your substrate. This can help avoid nutrient overload.

Having PPM testing tools when growing weed can also reveal nutrient absorption issues.  

Examples include nutrient lockout, where an excess of one nutrient prevents your plants from absorbing other necessary nutrients they need.

Similarly, since PPM testing tools aren’t limited to measuring nutrients, you can use them to measure other elements such as oxygen

Oxygen is essential for your cannabis’ roots. Low amounts (8.5-9ppm) can cause your plants to stop absorbing nutrients.

The main tool you’ll use to measure PPM is a TDS meter. It’s a small handheld that indicates the number of chemicals (in milligrams) within a 1-liter solution, typically water.

Carbon filter

Carbon filters are one of the best indoor grow equipment you can install in your grow room. 

Weed is known for its solid odorous smell, and terpenes are the aromatic compound responsible for its distinct smell. 

Carbon filters can help contain the dank smell of cannabis from leaking out of your indoor setup through the ventilation system. 

This is important if you’re trying to grow weed discreetly or simply want to avoid complaints from your neighbors.

The science behind carbon filters is that they trap odors through adsorption.

In this case, the terpenes produced by cannabis will adhere to the carbon filter attached to the ventilation system. 

It allows you to catch the strong and distinct smell of cannabis while allowing old air to cycle out and replace it with fresh air.

Grow tent

Grow tents offer the same benefits as having a dedicated grow room. You can cultivate weed all year round if you have one.

This is because you can control environmental factors like a standard grow room.

However, what makes grow tents infinitely better is that they’re much cheaper than setting up your own dedicated grow room. In some cases, they also use up less space.

Growing tents have other benefits, such as keeping most pests out, giving your plants the right amount of light, and protecting them from sudden weather changes and temperature shifts.

Because grow tents can come in different sizes, you need to consider carefully when purchasing one. 

The strain you’ll be growing affects many things such as height, width, and length. 

For example, you must have a tall grow tent if the cannabis strain tends to produce tall plants.  

If you plan to top your cannabis, you need a wide enough area to have room for your plants.

Other factors can affect the size of the grow tent you buy, such as the number of plants you plan on growing, the grow lights you use, and the other growing accessories you will install.

FAQ’s about weed growing supplies

How much is a weed-growing machine?

A weed-growing machine is a way to help you grow cannabis by automating most of the processes involved in growing cannabis. Some models can even test for pH. Typically a weed-growing machine would cost around $1,500 to $2,500.

What do you need for a grow setup?

The bare minimum indoor and outdoor growing supplies you need to make a grow setup are pots, seeds (or clones), and soil. In some cases, you won’t need pots or soil for your outdoor setup, but it can help reduce the number of pests and soil-borne diseases on your cannabis.

Do you need a grow tent for hydroponics?

No, but there are benefits to combining the two. By installing a grow tent around your hydroponics setup, you would control the climate and lighting around your hydroponically grown weed. You would also reduce the odor around your setup by keeping it within the grow tent.
