First of all, we should note that autoflowering marijuana plants are an exception, and we recommend a single final transplant in their cultivation. For more information about this, we recommend that you read the post about growing autoflowering marijuana.
Doing several transplants allows us to multiply the root area, therefore, to enhance absorption of water and nutrients necessary for producing large buds.
When the roots have colonised the whole of the container, you should do second transplant, usually just before flowering. If you are growing regular seeds, you may be interested in doing so once you have identified the females and males so that you save some soil and pots and do less work.
Marijuana plant, once it has been transplanted
Using larger pots at that moment might be a bad idea because there is the risk of the soil staying wet for too long. In this early stage of growth, plants are sensitive to mould, so a smaller pot is preferable so as to keep the substrate somewhat dry. Moreover, the roots tend to grow towards the walls and the bottom of the pot, so the entire inner/central area of the container will remain empty.

Preparation of the substrate to transplant the cannabis plant
This time the transplant will be to the final container, and again, its size will be different depending on the growing method. When growing indoors, growers tend to use pots of 3 L and 25 L or more, and outdoor growing is usually done in pots up to 100 L.
It should be noted that a transplant causes the plant to stress. It is normal for the marijuana plants to not give signs of growth for a few days, but if you have been careful, you soon will notice the positive effects of the transplant and the plants will thank you.
Usually, throughout the life of our marijuana plants, at some point we will have to transplant our plants to a container or larger pot, usually more than once. It is important to perform this task because the container will eventually be too small, and it will hinder the normal development of the roots and thus the growth and health of our cannabis plants.
