I think you would need more then 1, but I think it would be a good solution for you. I'm not sure if they are available in the lower spectrum's needed for flowering. The 6700k's are surely available but those will only get you through veg cycle. For flowering you need a lower spectrum bulb some where in the 2700 to 3000k range. T5 for sure has these spectrum's, not sure about this one. You might contact a flourescent supply house in your city and see if they can obtain the correct spectrum. That's how I got my first set of lights. Usually takes a day or two to get everything you want, but it's faster then ebay and usually cheaper.
