You can use those CFL. they are the 150w replacement bulbs correct? they work for veg. I def would suggest ,Depending on grow space, at least a little 150W hps during budding with the cfls
i used to use cfls, then i kept having to buy and buy more to keep my plants healthy during flower; then i finally got the hps and now its smooth sailingggggggggg
Thats the root of alot of arguments on here. Yes you can grow weed with cfl, led, mh, hps, or shit even incandescent. Nobody argues that they don't work, the point (I think) is how well compared to how much money. Every time you do the math MH/HPS wins.
hands down. buy the time you buy all your cfls, you realize, shit 20 bucks more and i coulda had a hps haha. i hated moving ALL my cfls every couple days as my plants grew. now i just raise my 1 bulb up and down a couple inches every now and then. so much simpler. its just that first step!
