Max Height

Hi all,

My new box is 2x2x4 (l/w/h) and i'm using a 150w HPS light. Does anyone have any input as to how tall I can let a plant grow before flowering? Also, would 3-4 plants be too much for my light/box? Thanks in advance!!

thats kinda small for 4 plants prolly start flowering after 1 month they would still be short
6-12 inches

It really depends on which strain you're growing, but I would probably start flowering when they're no taller than 8". Some strains double in size when flowering is induced and some triple. You might want to look up some information about the particular strain you'll be growing.
