Hey Sis.
Even 400 to a 600 w jump will be huge increase in yield muchless 400 to a 1000 .
Justaseed threatened to do a 1000w cooltube scrog but I haven't seen him post in a while ? I pay attn. to lumen output myself . 600w = 100,000 , 1000w = 135,000 . Im not real sure about the smaller lamps - these #'s are hps btw. not mh .

Hydro shouldn't be any problem for them esp. w/ all the reef tank exp. but does require alot more attn. -n- upkeep . Keep us posted M/L .
Peace
