GPS Cackleberry, HLG Scorpion Diablo, Jacks 321

Probably a day late and a dollar short but you might be able to hang the light directly from the crossbars? Maybe buy you 6-8 inches?

Just had to do this with my qb288 in a 2x2. Used the little cable hangers that come with the light, and ran them over the cross bars in the tent.
 
I have the HLG 650 R-Spec. I have had great results with it. I got the 650 Diablo before that. It's the square one. It has a hot spot if you're not high enough. That thing will smoke your plants. Way too powerful. I have it turned way down for veg.

How close do you have it close to the canopy in flower and at what capacity? Thanks in advance.

I think the R-Spec is about 15" at 750 on my par meter. I'll check the distance and the knob when they come back on.

Even then I am getting some edge leaf burn. The R-Spec is also a powerful light. My last two harvests were successful.

Yeah, I'm getting burn at 80% power with light being at 24"-28" from tops.
 
I had that wrong. Thanks for the reminder.

I was at 12" and over 900 par. I think it's 70% on the knob. I turned it down a hair before I fried them beyond help.

Thank you.
