I like working in 1Gs
I’ve gone bigger and it’s fine but 1Gs work for my space. Maybe 2-3 depending on what I’m doing.
The main difference is keeping up on water/ferts. Hard to do in a tiny pot that needs water 3 times a day unless you automate.
I veg 6 weeks in 1L and by that time they’re a real pain to keep up with.
Off the top of my head I’m thinking a pound in a 2x4 with 6G of medium.
