If the light footprint allows, drop it some more. You are trying to cover quite a bit though.
Light intensity increases x the distance squared.

Actually That’s backwards. Note the final sentence:
Inverse Square Law, Light
As one of the fields which obey the general inverse square law, the light from a point source can be put in the form
where E is called illuminance and I is called pointance.
The source is described by a general "source strength" S because there are many ways to characterize a light source - by power in watts, power in the visible range, power factored by the eye's sensitivity, etc. For any such description of the source, if you have determined the amount of light per unit area reaching 1 meter, then it will be one fourth as much at 2 meters.

Yeah, that was a good bowl. And that illuminated inside plane is expressed as...?

If I understand you correctly I believe the answer is “A”

That's actually an old diagram from a lighting class I took to define a foot candle unit of measurement. Been a while since I've seen that one, thanks!

GG x CD, OC x CD... GG needs to stretch out a little bit more, then I can fill the net out more... OC budsites are more spaced out, but there's a lot of them!!! Lights hitting everything, but I need 2-3 more to cover the whole thing... Pineapple Express autos in the back... How am I doing so far with this one??? Should I try to take a few of the leaves off the GG x CD???

Sorry, yeah that's what it is... I just refer to it as a qb288..

Hey @Frank Nitty how far do you have the lights now from the canopy?

12-18 inches... I think i need more light, a bigger spread of it... Hulk need more POWERRRRR!!!

Well that's your main engine.Your grow looks good! Frank i just try to imagine air flow like tunnels almost thru the canopy. If that fan leaf is deep inside or having all of it's light blocked it's more of a hindrance than help. Open her up some just be choosy witch one's you cut out. One last thought clean up those dead leaves laying on the floor.Real good way to invite bugs.

So I should really raise them up some then???

No. Don't raise them.
I just have a Sky Dweller finishing about 5" from the top of the buds. Same Hlg-135. No burn, plant was real happy today.
