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 its not very dense, just 4 plants in 5gallon pots takes up tall the room
Flipped to flower 2 days ago, 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? Also is bleaching even an issue if the canopy temps are so cool?
