Wtf Roots

there are roots sticking out of the drainholes of my 1 gallon pots the plants are just over a month old. replant?

replant, to 3 gallon, and then flower

yea i was thinking bout that I have 5 plants in a closet with a 400w hps think I should flower them soon?they are like 6-10 inches tall.

sometime soon, maybe a few more days, 2 more inches or so. up to you though, if you want to wait longer and get a bigger monster, totally up to you. and what space you have anyway

4 x 2.5 x 10 closet

if you really wanted you could grow monsters in here, of course it would take longer. up to you. 8-10 weeks after you set 12/12 youll have buds no matter how big they are when you start, but they will double to triple in size.

Yes a sign that they are root bound.
