I cant seem to find a MH fixture that has a cooling fan if it does not also house florescents. Dont I need a fan to keep the temp down and prolong the life of the bulb??
kind of a side question but when i get my mh's set up and ready to go i have a window unit that has a thermostat on it. should i set it slightly lower than the temp i want my tank at or equal to it?
