that will be fine for seedlings but after a few days you will want moooooore. I got this going in my rubbermaid with 6 23w CFLs, 4 6500k and 2 2700k, with the 2700s in the middle of the lightbar. This was germ'd august 31st, pic taken a few days ago, so its a bit bigger now and I've started to LST.

Hope that gives you a good idea of what you will need.
