i forgot to say he has 2 plants what look a different strain to the rest, they have thicker stalk and broader leaf, and much more bud on.
he is using 600w hps bulbs, 1 on 3 plants, the bulbs have been used about 5 times would that make a difference.
the max temp is about 85f and it dipps to about 70 when lights are off.
some of the plants have stretched a bit were as other aint, they aint very consistant with height, some are bigger than others
The plants are in coco, he hand feeds them, he uses cocoa-b, and also cana boost accelaration
I WILL UPLOAD PICS LATER
thankyou for your help
