thats awesome, thanks for the info guys. the ones i have are 36w. Ill use them while vegging only then. It really doesnt matter about how many im going to need since my bro works at a fish store, he gets pretty much whatever he needs for free. He actually sent me this link to see if maybe these types of bulbs are better (for flowering that is).
