The research done by the owner of the grow shop I visit showed that the mix of 1/2 red and 1/2 blue from start to finish work best. Jeff's son Peter is the first one I talked with about them. This was at the start of thier research about a year ago. Jeff started his Hydro Shop located in East Lansing, close to MSU, in 1983 and has been in business in that same building since then. When Peter is willing to tell me, the t-5 will outperform the 600watt hps and give a more even grow with less heat issues, I listened. I have spent a few thousand in their store, I don't think they are trying to piss me off. VV
Thanks for the info VV. They guy at my local shop also uses t5's, just for Veg though. He enjoys them alot, and as far as out performing a 600w hps, I would have to say that it depends on the application! Anyhow, do you think the more expensive t5's are worth the money? I am sure that the reflectors that cost double the price are nice, but are they worth it? Thanks for your advice so far VV, taker easy....DCG
