Well. Blue light doesnt do much for your plants. There are folks who complained that algae grew abundantly with the blue light. Try to get a T5HO light and use 2 daylight bulbs in it, each with 6500k light spectrum. your plants would thank you.
I did a quick search in ebay and saw this item for about 40.
