I have a new light coming, using 2 110W Giixer LEDs ("1000W")

I have them 17" above my canopy and my plant loves it. I have a therm gun coming tomorrow so I'll know my leaf surface temp tomorrow. I'm pretty sure 220W led should be 12"-30" from the top of your canopy. I hate that it's such a big jump 12-30

But tomorrow once I have my therm gun I'll be able to tell what the best distance is for these lights lol.
I believe 85⁰ LST is the sweet spot for cannabis plants. So let's hope I'm close.

The therm gun would be more useful for HID lighting. When it comes to LED's light bleaching is the main concern due to the intensity of the light and not the heat. 110w Giixer fixtures aren't all that powerful so 12-18" should be fine.
