Do you know what strain of bud you are growing? Typically unless you're SOGing it what I have been told is that unless you are growing a naturally short strain then about 40 inches or a bit more.
How long did you have these plants in a vegetative state (from clones or seeds sprouts)?
i had this from bag seed im sorta new to this and for the first month i was being
noob stupid I over watered and had major pH issues so growth was stunted
but i got it under control with a really good flush and lots of research
they were in veg for 2 1/2 months but its growing fast in flowering now. I keep the 4, 23w 2700k cfls about 2-3" away they are on 12/12 for a week and five days and its grown 7"
i have roots sticking out of the bottom of my three gallon pot can i transplant it into a 5 gallon pail without stressing her out and turning her into a hermie
by the way the avatar is the plant in question
