What kind of gram per watt yields are you pulling under COBs/Quantum Boards/Strips?

So I harvested about 450 g wet, 350 trimmed and probably about 150g dried and cured

In my experience 20-25% of the hanging wet weight is my final yield. I wet trim before weighing and hanging so there is not a lot of leaf weight. On Friday I harvested (partial harvest - I'm letting the lowers go for another two weeks) my Harle Tsu and got a hanging weight of 692g. I'll de-stem it and jar the nugs when the weight drops below 170g. After almost 5 days its still not quite there - this is my longest drying run so far. Some of my runs have dried wicked fast - one batch was crispy and way overdry in like 3 days. When I jarred it the humidity was like 49%. I had to toss a few fresh fan leaves in it to get humidity up.

I'm curious to hear what kind of grams per watt you guys are pulling under efficient white LEDs.

Ive pulled as high as 1.25 grams per watt under chinese blurple panels, sadly I havent pulled a harvest under cobs/qbs/strips yet but I am about to and it's looking promising. I am hoping to get in the 1.7-2.0 gram per watt range under the two samsung F series strip lights I have right now, but I might get a bit less since I dont use CO2. I do run a fuckload of airflow through my tents though.

Its varied quite a bit from about .6 g/w to right around 1 g/w. My last plant was about .7 g/w and like Canadian it had major issues that stunted it. The two before that were much better at .9 and 1.0. They would have been better if not for losses due to bud rot.
