Hello, I have someone trying to talk me into using these Sun System Sun Blaze T5 48" light fixtures. Has anyone used them for vegging? If so do they work as good as using 1k HPS light? I am kinda liking them because they dont put off the heat and would save on electricity. They are pretty pricey though. Guess there are two differnt types of bulbs to choose from, Veg and Flower and would use the Veg one and then move plants over to other room with 1k HPS lights for flower. Thanks!
