There's a dude on here that manages six in a 2x4. If your keen for mega defoliation you can fit anything anywhere as proven by a lot of members here.
Yes get the 2x4
I grow 4 plants in a 2x2x6 under a Viparspectra xs1500. It's perfect if you grow them SOG style.
I also have an air scrubber......when it's all closed up you can't smell shit. Even at the end of flowering it is nearly unnoticeable.
Totally agree about the ready made kits. It's much better to piece your setup together with individual components. The price won't be much more and you will have much better quality.
What strain? Nice and shallow scrog, I guess mine is less a scrog due to 12-18” colas being right up instead of shallow. Hard to do in a 2x2, that is why I ask. It gets too dense, too quick due to no direction to weave in.
That's a lot of foxtails. Is it a sativa leaning plant?
Same plant I had lately that I just posted a chop journal for, almost done. 30 reduralis 60 indica 10 sativa but wow it was a spear grower. Used a light meant for 3x3 instead of 2x2 and ran out of height. The tops grew like 4” taller, kept stacking.
That was crockett family farms tangie. In hindsight i should've stopped tucking earlier.
5 plants is a bit much in there.
