Drive by... Tead is 100% right... I can't use my HID in the dead summer... Well I can, them hot days I dial down the wattage...... But heat is always a big thing,,, but is 100% workable with a good air cooled hood like a cool tube''' in a tent.. I don't like these purple things so far to start my spouts.. Least that's all I've ever tried... So far. But they are 'cooler''''.. I damn near need to heat my tent in the garage?? I just shut down my LED for my HID there. LED temps ran 65 degrees in drit on the ground,,,,, My 600 watter in a 4X4 is about 78-80 degrees. But in the dead of summer I run a 400 watter,, and I run a open hood,,, a cheap one......
BTW I gifted Lazyfish some of them UD seed................ I think he's going to pick your brain abit............ GL and Keepem Green my Friend
