I don't know about indoor composting though, I have no experience with that. I have a compost on my balcony that I feed with organic kitchen waste, with dry leaves of the plant residues that grow on the balcony and mixed with soil to speed up the decomposition a bit. It needs dry and moist in equal measure.
That you are most interested in the cannabis harvest is obvious. LOL
Yes, growing your own fruits and veggies would take up a larger space. From my childhood I experienced my parents' garden and it was a lot of work, on the other hand, once you get the hang of it, then again, it wasn't.
I think, the willingness to do and be motivated to try new things, for example, is when people near you have a great interest in them themselves and "drag" you with them. HaHa!
Sincere greetings to you!
