Best Pot Size for Cannabis Grow

Pots come in all shapes and sizes, but which ones should you use for growing? Read on for some tips on the best pot sizes for your cannabis plants.

Choosing the right pot for your cannabis plants can be a little confusing when there is so much choice on the market. If you are a beginner, you may be overwhelmed by the different types of pots you can grow in. This guide is designed to simplify the process for you and maximize your yields with the best pots.

First and foremost, you need to provide space! Pots with enough space for roots are key to successful growing. Your yields will be higher if the roots are happy and healthy, so make sure they have plenty of space.

Bigger pots, bigger yields

Deciding on pots can determine many things about the success of a crop. The best pot size depends on what results you are trying to achieve.

If you are looking for large yields, large pots are recommended. If the plant is restricted by a small pot, this makes it difficult for it to sustain growth and you will only end up with a smaller yield.

Bigger pots, bigger yields

Roots grow very quickly and do not like to be pot-bound. If the roots are not allowed to grow properly, they start to block nutrients and stunt the growth of the plant. Remember that everything grows from the roots. Roots need space and if they are restricted then they won’t be able to fully develop, which means your plant won’t either.

Only grow one plant per pot. You don’t want plants fighting for nutrients or space.

6 things to consider:

  • How big is your growing space? Consider the size of your grow space and think about how many plants you can fit without overcrowding.
  • What is your budget? If you’re on a tight budget, choosing robust pots may not be the best option.
  • What kind of yield do you expect? Larger pots mean higher yields.
  • How many plants do you want to grow? Manage them accordingly and many small pots can work really well in a small space.
  • How much work do you want to put in? Large pots require harder work, heavier lifting and more cleaning.
  • What variety are you growing? Plants that are tall or need to be grown outdoors usually need larger pots than short and vigorous varieties grown indoors
Tip: One of the best ways to make the most of pot space is to repot. Starting in a small pot allows the plant to develop a root mass without the roots having to expend too much energy searching for nutrients or water in the initial growing phase.

The Best Pot Size

There are all kinds of pots in many different sizes. The average pot size for indoor growing is about 2.5 gallons (10 litres). Don’t reduce the pot size too much below 2 gallons, as the plant may not have enough root space to grow to its full potential.

The Best Pot Size
Ideally you want pots that are large enough for the plant to be fed or watered daily. It's not a good idea to have a massive pot that you only water once a week, as the plant won't get the regular dry/wet cycle it needs for proper oxygen or nutrient absorption.

Small pots

Small pots can be used in the early stages of the growing process to make the plants easier to manage. If you are germinating a lot of seeds, it may be a good idea to start them in small pots to transplant them later. Repotting is a great method if you are using a vegetable garden for indoor or outdoor growing.

Indoor

Growing in a tent can be quite tricky when you’re in a small space, so before setting up, imagine how you’ll need to navigate the space when it’s full of plants. You want to have easy access while still giving the plant enough space to do its thing.

The standard pot size for an indoor cannabis plant is between 2 and 6 gallons (7-25 litres). Anything larger than this can end up being too difficult to manage inside. It all depends on the space available, but you will need to reach the plant for things such as watering, cleaning or moving.

Outdoor

If you have a large outdoor space, you probably want to buy larger pots. As you know, larger pots tend to be associated with higher yields, so try growing outside if you have the option.

Also consider how long your growing cycle will be. If you are planting in early spring, you will probably need a larger pot to support the plant’s growth throughout the year.

If you are not planting directly into the ground, a 10 – 12 gallon pot is recommended. There are increased costs of using larger pots as well, as you will need to fill them with nutrient solution.

This is why outdoor plants grown directly in the ground can end up being so huge; because the roots have an infinite amount of growing medium to grow in! It is worth it to make the extra investment in bigger pots if you can afford it.

Conclusion

There are many factors that determine what is the best pot size to use, so it is better to go a little bigger if you are unsure. Your plants will be happy to have more than enough room to sustain their explosive growth throughout their lives. Try a few different pots and see the results for yourself. In the end, only you can decide which pots are best for your setup and requirements.

  • Interesting article, no matter how transparetic the pots are, it doesn’t do the cannabis roots any good, personally I prefer bigger pots to smaller ones 🙂
