Types of Pots for Cannabis Plants

[boton_semillas_feminizadas]

Many growers that have just started their journey tend to have a lot of questions about this entire process. Of course, this depends on what you’re growing and what you want to get from it. Today we’re going to talk about transplanting your plants and choosing a pot for each growing stage. There are plenty of types of pots for plants you can choose from.

Knowing when to transplant your weed plants is very important to avoid transplant shock. 

The first thing we need to think about is what type of seeds you’re going to plant. By type we mean autoflowering seeds or seasonal seeds, which can be feminized or not. Let’s begin with feminized seeds.

Transplanting Feminized Seeds to Appropriate Types of Pots for Plants

Plants will also end up stretching their roots to the edge and the bottom of the pot while the middle would be completely empty with hardly have any roots. When the plant goes into the flowering period they need some extra space to grow their roots downward and begin producing flowers. If they don’t get the transplanted when they need to, they’ll get spots on their leaves that might look like an illness, but all they need is a bigger pot to avoid root bound.

Types of Pots to Start the Process

You’ll need to transplant your plants various times as they grow so they can grow a dense roots system in order to have a good flowering period and proper nutrient absorption. Choosing the right types of pots for plants is very important.This way, they’ll yield more than if you put them straight into a large pot. The first thing you need to do is germinate your seed in your preferred manner. A small plastic pot or clay pot will do the job for this stage.

Then, once it has germinated and has four or five sets of leaves; it’s ready to be transplanted to a pot where growth can be relatively comfy.  3.5L pot would be perfect for this stage and if you’re planting indoors you can stop here. If you’re growing outdoors, you will be doing a few more transplants.

Other Types of Pots for Different Growing Stages

Every time you transplant your cannabis plants you’ll see how their growth shoots up straight away, and you can tell they’re growing day by day. As soon as you notice they stop growing, it’s time to transplant your cannabis plants again. If you want to keep up with your plants’ growth, then you’ll need to move them to bigger pots. 7L pots are big enough to use during the flowering period when growing cannabis is taking place indoors. More transplants will still be necessary for outdoor grows.

Once 7L pot is full of roots, it will need a bigger pot to not damage the roots. 11L pots are a bit too small for this phase, so you’ll need to use an 18L pot. This is the second last transplant for outdoor grows as your plants will begin flowering around this time. 4 months should have gone by at this stage.

Flowering Signs

As soon as you start noticing flowering signs and growth spurts in the branches, you need to transplant them to the last pots. This can be done in 50L pots or directly into the ground if you have the space to do so. Make sure to always choose the more appropriate sizes and types of pots for plants. When the plants enter their flowering period they shouldn’t get transplanted anymore because the buds could get damaged.

Basically, what we’ve been doing is allowing the roots to grow bigger and bigger. If you plant straight into a large pot, it will be super empty on the inside, and the size and structure of the plant is directly reflected on the size of the roots. Knowing when to choose the right type of pot for plants at the appropriate moment is very important.

Transplanting autoflowering seeds

Autoflowering seeds are very different from seasonal ones. They grow different too. The best way to get the most out of these seeds is to just transplant them once. All you have to do is germinate them in teku pots , wait a few days until the seedling grows a bit and then transplant it straight into its permanent home.

What benefits are there to doing this rather than just germinating it in a large pot?

Well, if you plant them straight into a big place, roots can stretch out a little bit more than you want whereas in teku pots the roots almost bend up on themselves. That’s when you need to transplant it to the pot. If the strain you’ve planted takes two months then you should move them to a 7L pot. If it’s a three month strain then an 11L pot would be better as they grow a bit more.

Once you transplant them you’ll need to bury the extra trunk at the bottom, which is 5cm from the first leaves to the soil. That way it can grow more roots, and the trunk will get much thicker which makes for a larger yield. You’ll need to keep an eye on how much you water your plants at the start to make sure you don’t drown the roots. If this is done properly, they will grow perfectly, otherwise they’ll stay small.

Autoflowering Plants

Autoflowering cannabis plants don’t get transplanted because they enter the flowering stage very soon and a plant should never get transplanted during the flowering stage. They grow so fast that transplanting them is a bit useless. Choosing the best types of pots for plants is very important for your yield.
