I was fudging for effect. It shouldn't be that expensive to buy meds in any case.

I don't think I've ever seen buds that looked like these do. Either way, they sure are super frosty! 5x5 tent with 8x QB304, running 2 per HLG-320H-c1400A, turned all the way down.

Well just got some depressing news. Someone was kind enough to test out a QB288 board for me at 500 ma at 18 inches the ppfd was 150. At 7 inches it was 500 ppfd. 
I grabbed 9 boards anyone have any ideas how i can use those 9 boards to compete with a CMH 315 (348 watts) in a 3x3 without using more wattage then the 315 uses and actually getting a decent ppfd ?
Open to any suggestions and truly appreciate any help.
Less boards pushed harder ?

Isn't 500ma only pulling 27watts from the wall? You're wanting 40 watts per board? i.e. 700ma.
3 fixtures of 3 boards on a hlg-120-700 would be a pretty efficient wall-to-wall. (if you really want to use all 9 boards)
Or grab constant voltage drivers (hlg-320-54) and wire them in parallel. Gives you room to rebuils/expand later.

because they can run at such a low amperage, doesn't mean you should. I wouldn't run these at less than 1000ma. At 50 watts, your running at 1/3 power, good efficiency and plenty of PPFD

From what im understanding 700 wouldnt cut it either. Less boards more amperage is starting to make more sense.
I saw a 90 watt board at 12 inches gave 1000 ppfd in the center of a 1x1 at the corners of a 1x1 it was in the 500's.
I think im coming from being in the mindset of cobs. A cob at 50 watts is killing it in ppfd its just not the same as a QB at 50 watts.

You bet!! Down here in Argentina blurpee is the only thing you can find, so forget about QB or even COBs to be available.
I asked a reseller for some "specifics" regarding a 3590 chip he had on sale and the only thing he replied was "This are some generic ones" LOL wtf is that
Anyway, I was able to contact the guys at HLG and they replied today, A FREAKING SUNDAY MORNING, telling me that they added the shipping rates for my country.
I have to say that even though I haven't bought anything yet, the customer service from this guys is awesome!! I'm really happy man.

Hah. They sure do! I knew they looked like something familiar. This is the only one of three Gg4 plants that are growing like this. She is also by far the most frosted.

I'm running 4 QB 304 at 85 watts each, and its too much as far as I'm concerned, at least without running CO2 . Take your measurement in a reflective tent, you'll see how much better they are than an open room. I kept my light at 30-36" until the plants got too big. And that wasn't stretched plants either, just big! Got to put a dimmer on it this time, all that lights a waste in veg!

30-36" in veg I'm assuming, right?
I had 3 ladies that had been flowering 5 days or so under p300s.
Put in 3 260w kits and they blew up when I was gone for 5 days. Not sure on exact measurements but at least 12-18" I'd say lol
That was with light distance around 24"
I understand the number of photons are increased by the increase in quantity of lights.Well just got some depressing news. Someone was kind enough to test out a QB288 board for me at 500 ma at 18 inches the ppfd was 150. At 7 inches it was 500 ppfd.

You should be at 800-900 range with that quantity.....

I have a question for everyone that mounts their drivers remotely.
I am trying to find out how to connect 3 of them in my mechanical timer without having to extend the Input side of the drivers.
I need inspiration or a new point of view, I have yet to find a solution that is clean
