that HPS puts out slightly more heat than a MV bulb, havent had troubles with heat, I disasembled the ballasts and put them outside the room, that took care of my temp problems, I have a 12" exhaust (low speed) in the ceiling, 2 80mm 12v PC fans and an inline air "pump" for intake to the room, only 2 clip fans for movement to the plants and another 80mm fan mounted in the hood. My room sits 3-5 degrees higher than the room next to it (no a/c btw) temps average btw 70-85 only hit 90 a few times.
4x5 Reviewed by 4x5 on . New log, six plants, first time vegging w/HID All my previous grows were done with cfls and floro tubes, However this time my seedlings are under my 2 175w coated MV lamps and cfls, I finished the remote ballasts and re-oriented the bulbs in their reflectors this week. I must say I am quite impressed, all six seedlings cracked the surface last week under 6 cfls at 18/6; after that week my new hid setup was ready, within 2 days under these lights, all six have a first set of internodes, this never happened to me on previous grows with Rating: 5
