i got a month old plant and it is almost a foot tall. i have a 2 by 2 ft and 3 ft tall stealth box i made. i just need to know when to start flowering so it dont out grow the box. how much do they grow during flowering???
depending on indica or sativa but anywhere from double to triple... try suppercropin to keep ur plants low and fill in the surface area of ur box as well as get the most out of ur lighting
