is height an issue in yr room? If theyre veg'd til 2' they could well hit 5' easily. But if they get too tall u can always bend them over a bit and tie the tops down, but yr yield from a 5' foot plant will be alot greater than what yr getting already, just dont forget if yr veggin longer you'l need a bigger final pot size to allow for the increase in root mass, but all this means more bud! I veg 5 seed grown plants at a time under 2 x 125w envirolites, u know the large high power cfl's with the standard E40 screw in growlight fitting? one in a reflector one hanging, did have 2 blue spectrum in there but i broke the hanging one a few weeks ago so i had to replace it with my spare red spectrum til i get another blue, they grow just as quick as when i was veggin under my 250hps with half the heat of the hps! Theyre that good i can get 2-3' (depending on strain) of veg growth in 8weeks, and take a few clones and root them, then leave them for a few more days to grow a little rootball then it all goes under the 600w hps in my budbox, not bad for 250watts of cfl! Heres a lil pic of my veg room i raised the lights a little so u can see them, theyre normally kept 2" from the tops. Plants are 3 big buddha cheese and 2 ghs NL#5xHaze mist all feminised, ranging 3-4wks old, they stay there til my church are done in 4weeks time.
