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 things to say about this light. I can say with ease that this is the best grow I have had yet...The low heat emition is a great big plus for this product. I never thought that a fluoro light would ever give me such nice plants. I have included some pics of the babies that i have on board...two weeks old !! Let me know what you think!
