The thing I think the cool tube is very useful for is small space and/or getting the light closer to the plants. I have my 1000w within inches of my plants. Without that I would have to keep at least a foot because of heat. I am definitely loosing some light to the glass, but 1. I think the proximity of the light to the plants kinda cancels that out... and 2. It's about the only way things would work having a vert setup in a 2' x 3' closet. If you are planning to cover 5' x 5' with one 600, then I would think it would have to be kinda high above the plnats to get that spread, so a cooltube is probably not necessary.I found a setup for under 300 on that same website with a digital ballast and comes with the HPS light bulb and the MH conversion bulb. Is it really worth it to go with the cooltube if you end up losing light intensity. Ambient temp in my house is only 70 and plan on hooking the inline fan to a climate controller. This way in the future i can add a CO2 tank. For now i have a kit that i do home brews with so im going to throw a higher temp brew in the tent with the plants. Kill two birds with one stone...haha. I'm going to go crazy untill i have my tent all setup and some little ladies growing. Gonna try out the CCOB method.
