I've been supplementing with CFL for flower and Cloning/Vegging with CFL since I started about a year ago. I have had decnt luck in a pinch at Lowe$. Go to the outdoor fixtures, there are a few viable options, not terribly expensive either. I just picked this up for 44 bux, with the bulb, cast aluminum housing, exterior rated.. Replacement BUlbs are like 12 bux. I haven't tried it yet but based on the "advertised"...performance it should do well for a primary light for vegging/cloning. This one is slated for one of my Wardrobe box clone environments. I will report back on its usefulness, I am installing it tonight. I could really see four of these arrainged They also have some 65w MOgul/blue spectrum for 9$ and ballasted 65W 2900k yellow small mogul at 19$. Wish me luck!
