    The really nice thing about ceramics is they are so good at bringing out colors and terpenes you don't have to cool the room to bring the traits out. I ran C02 until week 6 and 85 degrees and I had colas so purple they were turning black. After I turned the gas off I'm running 75 lights on and 65 lights off. It's been getting cold in Portland so even have turn the heat pump on sometimes.

    Iam in Michigan. Freezing cold outside this time of year. I have a louvered intake that i strictly use for this time of year. I shut off my mini split the whole winter. I thought it crazy to run the room with the split on these months when its 25 degrees or lower outside. Saves me bucks. I have a six inch inline blower hooked to a simple themostat hooked to the louvered duct flap. Keeps it just as cool as the split...virtually no money spent. But anyways...sounds like a bunch of lec 's are going to replace my Gavitas...soon....real soon. It makes so much sense. And really..the whole hps spectrum from the very beginning was meant for fruiting crops in a greenhouse. Where the blues of the sun was plenty and the reds needed supplement. Makes sense that people are seeing improved crop quality totally indoors with lec spectrum. We used hps all these years because thats what we were told first off. All we had second (besides mh). And thats what gave us plump buds. But the whole hps spectrum was never ideal for the only light source.

    I would too but I like to keep my room sealed. Plus you have to if you're running c02. Or at least to best of your ability. Unless you like refilling tanks everyday.

    I do use more co2 with the cold air intake in winter...but not by much. The intake louver opens up but sporadically. It drops the temp quick..then closes back up. I lose some co2 but its negligible at best. And worth it to not have the split running..throwing cash to the man every month.

    Sorry to revive an old thread, just thought someone might be interested in my experiment. I wanted to know if I could run cmh's on standard high frequency electronic ballasts as there wasn't sufficient information out there pertaining to that.

    Background:
    -2x3x5
    -2x400w hps
    -wing reflector
    -air cooled glass diy enclosed top
    -adjustable ballasts run at 300w(for 315 cmh)

    Lights ran without issue for two days. Then on the third day, as I was in the next room watching tv; all lights, tv, stereo all shut off for roughly five seconds before powering back on. I immediately checked the box and found the lights off. Everything else had turned on and worked fine except the lights in the flower box. After checking all breakers, fuses, panels and connections I switched the cmh bulbs for the hps; fired up no problem. The cmh bulbs are intact without any apparent alteration and no breakers blew there having been four between bulbs and main power. So I am inclined to believe the bulbs overheated emitted an EMP temporarily shutting off power to the rest of my house without damaging anything.
    Thoughts?
