Not too bad, if you're wanting to flower from seed keep this light. If you're interested in vegging then get some 6500k CFL's about 50w-100w per plant is good.
Veg is the third stage of growing.
#1 soaking seeds aka cracking beans
#2 seeds sprouting aka Seedlings
#3 Veg growing
#4 flowering aka buds
You should have 6500k likes for the first couple of months before you go into flower.
Vegging lights on 18 hours off 6 is best but you could do on 24 hours not so good
Flower 12 hours on 12 hours off.
You can switch lights anytime you want aka flipping switch to flower. the longer you veg the bigger plant will get and more buds
