I'm building my grow box inside a computer case, I don't have the money available right at this moment to get any 26w cfl's. Will two to four 13watt cfl's work if I'm only going to be growing 1-2 plants at a time?
It will work poorly for one plant. 100 actual watts is the standard, i shoot for 175w per plant. Keep'em Burnin DirtyViperMan
