color would do fine but it's 21W and its 3 feet long... so this light is not enough, If I would need to use from what you have, I would put 2 cfl per plant for first 3 weeks it should be fine, so 5 cfls with that t5 is even better for vegging. Of course it depends on how long you want to veg, but if not more than 4-5 weeks, you're fine as long as you keep them 1-3inches from tops.
