Hey guys, been lurking around here for a long time learning the tricks of the trade and using every avoidance strategy possible to not hang out in SNS... until now, and this time hopefully it's to give back a little. The other day I got a little over excited and purchased this fixture to start...

So I just bought a 20 Long, and the hood I got for it, comes with a 24Watt standard full spectrum fluorescent. I cant help but notice, the light looks a little low. I have the option of buying a t-5 HO 17 watt, think it's a better choice? Will it provide more light for the plants?
