Man a thread asking for honets cfl grow thoughts sweet lol.....Well the cfl bulbs suck doney dick big time. They dont cover enough area,put off to much heat for the amount you need per plant, the grow time is amazing as slow as can be, the yield after that long wait is very poor, the buds are very airy and non compact.The only use able cfls are the kind like environlight or vitalumnes whoch are actual 125 watt or bigger the bulbs are 18 inches longs.Now if you talk straight florescent bulbs the T8 and T5 tubes when used with enough are great for an entire small grow.I use T8 lights to veg plants but go to my 600 and 1000 watt hps lights for bud as you need them to get a good yield with hard tight sugar coated crystals.Just before any cfl lovers come to flame me for dogging them this thread asked for everyones 2 cents and thats mine. I bought cfls and put them in every house outlet I had to drop my electric and then use my hps lights with little extra cost figure a 1000 watt light on 24/7 adds $45 a month to your bill but changing 15 65 watt incadescents with 23 watt cfls you make that up and more and its actually cheaper to use then when your not.
