Saw a grow light on Cl and i have been wanting to get one for cold snaps and such when I have to move my peppers inside. Well I saw and ad for a lumatec 400w dimmable ballast, with bulb and 6 in air cooles hood, all in the box I offered 150 and he said sure. Everything is still new, and in plastic, so I ended up with a hortilux HPS bulb, new 6 in inline fan, 25 ft ducting, ballast, hood, and to sweeten the deal he threw in a Secret Jardin growtent, it's like 3x3 but that enough room to start seeds in, cept I started most of mine already... I will be prepared for next year, I don't know if it will get cold again this so called winter, it's 83 here today.
