ive heard dutch masters use fl all around the bottoms and 400 hps for two reasons---one being the extra light at the bottom and two it cuts down on elc use ...main reason of being busted out there i guess....
i dont like the sound of hps's or the heat ...or the elec use
flourecents are so cheap ...i was thinking of like 20 ballasts which is 1600 watts----i can get ballast from this old school for free ---bulbs well ...you know-----i was thinking of lining whole room in white plastic...and hanging
from every direction ....ahh im stoned right now and maybe its more work than im thinking ,,,i guess i could build stands for the ballasts...
any ways ---ive had some bad ass buds from 4 ballasts total so i guess 20 would be good for a small room ...
