Welcome! That depends on a lot of things... available space, desired yield, time available to spend with the garden... it goes on and on. What are your thoughts on this?
I have a lot of time to spend on it. But i dont understand why. Its my fisrt time going to grow a plant (and thats cannabis). Im gonna use a regular space. I have a lot of free space, but i only have one LED lamp. So im gonna plant 4-5 plants.
So, how big is the footprint of your one led lamp with decent enough PAR to flower pot? That should decide for you how much space you really have. Regarding time, the larger the container, the more time between waterings.
