I'm using a small tent. 2x2. I find it a lot easier to manage... usually one plant at a time but it appears like I've got 4 Pineapple Chunk seedlings at the moment
Might just keep all of them and turn them early and let them do their thing and see what happens.
I'm using the same old hempy buckets with 100% perlite and topped with expanded clay pellets. I feed depending on how the plant wants to eat. I use GH 3-part nutes and I'm mixing equal amounts and tune the EC accordingly. Towards the end of the grow I add in a little extra PK or pull back on the N
Lighting is LED. older gen LED but they do their thing. Two CXA 3050 and two Vero 18. All at 1400mA; around 185 watts. Big ass heat sinks 30 cm x 20 cm so heat is not an issue.
I don't think I'll upgrade any time soon unless I decide to move house, but that's not foreseeable in the near future.
ATM my main problem is smell. I use ONA gells but I'll need to figure out a way to put a carbon filter in there >_<
