Yah all you need to do is keep your plants closer to the light, and/or get a stronger light, either a high pressure sodium or a metal halide light system. You need a decent amount of light to get some bud. If your just using a few fluoro's your going to get like 5 grams in the end. lol. You should get like at least 10 for a plant if you want decent results. And actually you should get compact fluorescent. Don't buy the fancy shit for growing, the cheap no name ones are just as good for growing cannabis as the expensive ones. You should probably buy a whole shitload of compact fluorescent light bulbs and make a grow chamber or something, or just spend some cash on a real grow light from www.insidesun.com they are cheap as hell and i hear they are good. Or you can just go to a hydroponics shop near you and get a light like the ones they have on insidesun or other websites but for alot more money. Good luck!! they look healthy.
