Hello,
A couple of months ago I got rid of my T5's and replaced them with a Turbo Grow 300 watt LED. I had been reading many Hydroponic forums and was convinced to give them a try. I have converted a large closet into my new grow area, and have been happy with the results. Roots/leaf/flower production has improved a great deal. I used to grow under a 1000watt metal halide, but it is way too hot and would probably set off the sprinklers in the closet.
As you can see the light color is not pleasant to the eyes, so I use a 45watt CFL when i need to work on my plants.
