first grow small grow box with 1 month olds

it just sucks how those kinda lights u have to wire up and it takes so much elctric.
i cant have that or do that thats why i use cfl's

electricity-wise, 150 watts of hps = 150 watts of cfl's. watts are watts.

but u could have alot more lights in general to equal that 150w
and u could have them alot closer too

actually, from what i hear hps watt for watt are cooler than the equivalent of cfls. so in theory that 150 hps puts off less heat than 150 watts of cfls. i can't say i know for sure though since i've never used anything but cfls.

the thing i like about it is you have one cord to plug in my timer. not have a bunch of light cords pluged into plug strips. a little less of a change of a fire.
