Is it intake or exhaust for you havc? Personally I would say bad idea, if its intake during summer you will be adding heat to the system, if its exhaust your looking at the possibility of adding CO to your grow area (not sure how CO and CO2 affect each other) and you will also add heat during...
6500k bulbs are easy to find and cheap, but I'm having trouble finding lower spectrum in mh (like 3000k or so) the lowest I can find is 4100k I can always supplement with cfls
What spectrum/bulb would be recommended with using mh thought? Do you use separate spectrums for veg and flowering? I am use to aquarium spectrums so 6500k to 20,000k it seems like I seed 2000k to 7000k with plants what would you guys recommend?
Thanks everyone I think I will get one and use it for a grow or two until I can get the funds for a new ballast. Now just curious would anyone use a mh for veg and flowering with a few cfls for supplement or go with a conversion bulb.
