I have 5 Trainwreck and 3 G13 x HP clones / cuts rooting... I have 2 400's one HPS-Hortilux and 1 MH-sunmaster warm deluxe @ 53 w p.s.f. in 15sq. ft... I grow in soil... The Idea is to let the clones get so big, that I can pull 1.oz off each plant... and still have adequate light coverage for all of them... if any one has experience with this, I would appreciate any imput... I plan to finish them in 5 gal containers... what do you think-???... peace.
