Okay gang, please indulge me... I got a nice home grown/ local brew buzz going and have a guestion. Just started an enlarged grow space with new 315 LEC light and struggled with temps too high during seedling stage. Even resorted to buying an air cooled hood to get temps in desirable range. Started out perfect. Now that I have been running new LEC lamp for almost two weeks, temps have dropped to the mid and lower 70's when lights are on and 4" exhaust fan is set on low. I took the glass cover off the enclosed hood (LEC's don't emit UV light through glass) and temps seem to have adjusted to the high 70's. Long story short... do LEC lamps have a "break in" period and then level off?
