Starting my first indoor grow soon. Purchased a 3x3 tent and a 300w commercial grade light. Been doing a bit of a deep dive on no-till and living soil farming and am interested in trying it out for my grow. My question is: Is a 3x3 too small for 1 plant in a 10 or even 20gal pot? I'd really like to try and create good enough soil to reuse and from what I've learned that only seems to be possible in bigger pots. Obviously planning on doing to a decent amount of LST and topping to make this happen, but just wondering if my theories are impossible before I try them. Any recs for living soil/no till indoor growing in relatively small spaces would be highly appreciated.
Definitely recommend using larger pots. I've been using two of these in a 3x3 with recycled organic soil:
https://www.agardenpatch.com/ Earthbox is another brand that's very similar that you might have heard of. I do either one or two plants per Growbox depending on how large they are. I guess the next step up would be a fabric bed or kiddie pool type thing, but the sub-irrigated planters make watering a no-brainer (which can be tricky for new indoor growers to get the hang of).
My soil is a mix of a bunch of stuff I've added over time, but lately I've settled on Espoma fertilizers and worm castings for amending between runs.
Good luck! Water-only organic soil in sub-irrigated planters is the easiest method I've found, so definitely a good place to get started.
