They are under 250w hps now.
They seem to love the root booster.
I am going to top them in week 4 and maybe another time in week 5 or 6.
I love them already!
EDIT: already topped them on December 5th because of their good growth
I soak them in normal tap water with pH 6.1 for 24 to 48 hours, when the roots are approx. 1cm out of the seed I put them in a box with a wet paper for about 12 to 24 hours.After that I use coco jiffys.Works great.
