Wanted to add, I don't see any issues with actually flowering out in a 3 gallon pot, will still bring a good harvest per plant, especially after vegging out for that long. Mine will all veg for about 2-3 weeks and then I'll place 3-4 in a 5 gallon pot, and do some light to moderate LST, with a topping a week before I move to 12/12, so each 5 gallon pot will produce 6-8 tops - Keep in mind that it's not really advised to put that many in the same container, but I don't follow the rules, I try to make my own.

So in each of my 5 gallon tubs I'll have 4 plants, with 8 tops, and I'll tie down each top to the opposing corner, and that will be about the extent of my LST - So when I do have 3 of the 5 gallon tubs in my bloom box, since it is a perpetual grow, it'll be very impressive, and won't be overcrowded by colas I've got 2 more weeks before I flip my current veggies over to flower, if you've kept up with me, ideally I'd like to start producing 6-8 ounces a month, we'll see what happens. Honestly, I'd be happy with 2 ounces per month, but I'd like to see what I can get out of this cabinet... No idea what I'm going to do with the overflow
