Light problem

Hi guys thanks for having me.if anyone has time how faraway should a 600w hps with a reflector be from the plants

I believe there are differences betweeen bulbs and fixtures.
You kinda need to see it on your plants how far they like it.
Put a temp meter at the level of your canopy. If the temp is okay, you shouldn’t have any problems.
The distance can vary from 40-60cm roughly.

This chart applies only if you are running single ended bulbs and air cooled equipment. (No heat factor included).
Bare bulb hoods running single ended bulbs I believe should be 18” from the canopy...but might want to check with someone else because I only run air cooled in my grow.

Saving this photo thank you.

No prob. If you do a google image search “HPS chart” this will pop up. If you do “MH chart” you can find another that has the same for a MH single ended bulb in an air cooled hood.
