I use a 2ft 4 bulb T5 light in the top of my cab. this height is like 3 ft tall the Light Is only 3inches in height. Its awsome. Plus the reflectors in the T5 lights are german technology which is supposed to be really good. I have yet to flower a whole plant through but here is a pick of A sexing process Im trying, I hope to have decent results.

the cfl raises the temps in my Cab by only 5 to 10 degress. It works well for hot summertime.

kdspecial Reviewed by kdspecial on . New Wave T5 Grow...IM NOW A BELIEVER !! Hello there fellow growers. I have been growing for about 4yrs now using 1 400w HPS and 1 400w MH with a conversion bulb, 800 watts of growing power.A friend of mine recently invested in the HO T5 system 2ft x 4ft 400w total power. I must admit that I was really doubtful about using this new technology of marijuana growing. After seing his results iin three different crops I decided to go out and get one for myself. Since I have started my new crop with this new light I have nothing but great Rating: 5
