Finally got a few good clones chemdog & big bud.. just started flowering 4-18-12. Every third watering Ive been using Kool bloom (liquid for now..two weeks Ill be going to the powder). Just ordered another hood so Ill be up to 3000 watts and Ive got 54 clones that rooted out of 58. Stems are the size of a quater already. Very happy for my first grow.
