Gentlemen, a question about my new flower setup I just flipped on yesterday. 600hps with digital ballast with large enclosed glass hood, my virst venture outside of CFL / T5's
How close is to close to the canopy before I start losing to much light to the outer edges of my tent? Im doing a scrog in a 2x4 tent and have the screen filled around the outer perimeter
Flipped to flower yesterday, installed the light Set the ballast to 75% dim (so 450 watts Im assuming) and took careful note of the temps/humidity when I flipped on the light, started way up say 20", felt I could go alot closer, 16" canopy felt breezy and comfortable with my hand under it, moved it down to 14", still comfortable, temps @ 78*. And a sensor put right out in the middle of the tent, no shade, was only 82*
So the enclosed hood must make a huge difference, and my exhaust fan was full tilt with a good breeze being pulled into the hood. But if I drop the light to 12" I feel I am almost shadowing the edges of the tent with it being 4' wide.
I plan on giving the plants the full 600w and putting the ballast to 100%, but last night was just a test really, surprised how low the temps were, lower than my T5 setup even
How would you guys handle the light height for this?
