Hey dude, what wattage....and floresents are good for vegging, but youll want to get either some HPS or Metal Halide lights for when they get bigger. 400, 600 or 1000 watt is good, 1000 best of course. If you really want to get 400 or 600 watts, be sure to get two and get some ventilation cause those lights are gonna generate a lot of heat....best of luck
Im currently using two 145 watt floresents to start off my plants...once they get big im gonna switch to the HPS. Those lights should be good for a bit but like just when you can try to switch the the HPS or youll get little stringy ass buds...
What we want to know is watts. Regardless I would look into a hps light. You can probably get away with one of those 275watt hps lights(under $100). But bigger is going to be better when it comes to lights.
I got my HPS 400w from lowes (just the light no ballast) $20, The light ballast was $82.12 from the electrical supply store ( this came with the ballast the ballast and the warmer or what ever that was [the complete wire set up] and no in my adventures building this i have found that the people in the eletrical supply store are not electritions so they can not show you how to wire it up but you might have better luck.). The box I built my self and then i got 3 50 cfm bathroom fans (for vetelation) for $12.18 each, the cheap fans can not handle to much of use 24/7 and will need to be replaced. I have 100 cfm going in and 50 going out.
hope this helps.
