First indoor grow for an old outdoor grower (advice)

I didn't realize that would be a problem as long as I kept the canopy temps down. So I can have the light too close??? The temps a foot away are approx 78 degrees. Outdoors was so much easier........

I should note that a 600w mh conversion bulb is in use right now. It flickers a bit. Is that normal. I have a 600w Super HPS but I was going to switch the bulbs when I switch my cycles.


Anyways................I was thinking about buying this next

Day/Night Cooling Temp/CO2, Night On Device (AIR-3DN)

Anyone have any experience with one of these units?

easiest co2 ive ever used was a spray bottle and some seltzer lol worked like a charm:hippy:


btw looks like an EXCELLENT setup goodluck
