Can someone tell me how close I could have my QB600 to my canopy during flower? Is 12 inches too close? I don't think I would have an issue at 12 inches with my QB 260xl but could someone here set me straight on both counts?

Cheers

600h I would do like 24in

I've got a QB600h and 2 QB260xl on a 8x4 table. Running out of height, just about done stretch though. The QB600 is sitting at just about 24 inches from the canopy, so I guess I want to raise it if they stretch any further...? This is a cool test for me, before I had 2.2kw HPS in the space so I can't wait to see if I can get a comparable yield, and what the quality will be with only ~1.1kw QB. I'm at 3000k, day 13 of 12/12.

you've probably mentioned it somewhere, so please excuse me, but... are you using a supplemental bloom light/bar ala RapidLED?

I don't think 240W is enough for a 3x3, that is why you have so many ball-shaped nugs.
If Iook at my colas, they are not giant, I suspect that would take 200W strips, but I have yet to run a large yielding strain under the strips. My colas are pretty large, well out of the ball-shaped nug territory, especially considering they were grown on 300W.
I don't mean to use you as a specific example, but I am trying to find anyone growing large colas using lower powered strips, say 50W or less.
And all I find is more of the same. I'm pretty poor, and did quite a bit of math before I worked out it would need 1 double row F-strip per 20cm, run at test current to equal the efficiency of a 600W HID.
I could find no shortcut in delivering enough photons than to actually put down the required Watts at the efficiencies the strips operate at. Having 59 strips is nice, but when you have to fit them in that 20cm space to reach the required energy density is another story.

I have a prediction that we will continue to see nice even beds of smaller nugs with lower power LED strip rigs rather than larger colas. As I said before, if they made a 3-row strip, I'd buy it in a heartbeat over any efficiency in a shallower field of light.... Unless I was running smaller plants, which is part of the next experiment. I will be running 6 smaller plants in a 2x4 under 300W. that is 37.5W/square foot. Harvest day is supposed to be on Monday, but I suspect I will be pushing it out to 60 days, as I have never had this level of plant health so late in the grow on this strain.

You are going to have a harvest of rock solid nugs. What I would say is the next time your going to scrog, super crop and defoliate from very early veg. You will get tighter internodal spacing therefore increasing bud sites which will then just cover the every part of your net.
