Good for you bro your definitely on your way
one tip for the dehumidifier is to use foil tape on any indicator lights that are on it so it doesnt throw out naners
other then that your fine just a LITTLE cramped ATM lol
Now i regret not just getting like 4 - 30 litre pots, a screen, and growing that way instead, i seen a vid on youtubr were someone did that, he topped them,let them veg for like 8 weeks, when the branches grew though the net he just snapped them all, within a couple of weeks he had buds forming on the sides of the branches, when it was done it looked like he had 30 plants in the room, every bud was a top, he totally pruned the bottom of the plant, seems like less plants in bigger tubs if you use them methods can be quite beneficial, plus uk law states that anything under 12 plants is a minor offence, so i dont think it matters how big the plants get either
