250w in a cooltube would run fineonly small , 60cmx60cmx140cm , i could go a little bigger but prefer not. I think a 250w HID would be enough in a cool tube.
Good info , thanks. I'll look up prices for that setup.Hey tarks, I have the same size tent (2'x2'x5') and have a 250w HID in there and just moved from a cooltube to an econo wing open reflector. I did this because there is a good 10% energy loss from the glass and shape of the glass. With a smaller grow like this I want to maximize yield and potency. I found the cool tube was not beneficial in my application.
Temperatures are pretty good 82F (27.7C.) Granted ambient temperature is lower due to the season. Just make sure you have a fan and carbon filter if needed.
Yea I had kind lights. Full spectrum just like those. They include alt of extra blue to get the par ratings up which are better for veg than flower. Mine had controls you could change each spectrum different intensity. Mine put out a lot of heat tho. The a51 are way cooler.Apollo's are 8 band including white. But there are a lot of great led options out there. Next to the Apollo in the pic I have a no name 11 band China made that performs just as well but the Apollo is just built better.
