Check out 8 autos, organic fed coco, 2x4 tent. Search @MeEasy he will load them up too. I currently have 5 clones in 3 gallon pots in a 3x3. This is from a week ago. They have grown a couple inches since then and I flipped on 1/31. It will get interesting to say the least. I usually grow 4 in 5 gallon bags
Then for kicks I have 12 single colas clones in 6" nursery pots in a 24x18 space
This is their underside a couple weeks ago
I guess you can pick a number and make it work.
