I would use the HLG320H- 1400. When a driver is rated at 320 watts that's what's it pushes to the boards and usually more. The HLG-320H-1400B pulls 360 watts with the dimmer installed at the wall @120 VAC.

So think your numbers guys. All efficiency numbers on website are at system level not board level. The best part....... They are all tested using an HLG-80H which is only 91% efficient....... We are switching all HLG 550s to the new HLG 480s 95%+ efficient!!!!!! Same light output less watts

So really using the 2 hlg320h-1400b it consumes 720 watts at the wall to replace a gavita 1220 watts at the wall. Not to mention the gavita 4x4 par map is crap near the edges, as in less than 300

No 2 320s As pull that much. 2 240s pull around 550-630 watts depending on A or B type driver. Honestly I would run no more than 600 watts in a 4X4 as these can be ran alot closer than a Gavita. Basically I like the HLG 550 which is 4 boards and 2 240 drivers in a 4X4. You can use the 480 driver for even better efficiency if you can get one.

The original plant turned out to be male so I had to throw a different one in and I didn't feel like waiting for the extra veg time so it went into flower smaller than normal. Plus this particular cut doesn't stretch a lot during flower but carries serious weight for a small plant, 9.5. The plant had plenty of light for the space, this QB light has more output than my 3590's that were built for the same size space.

What was the dried weight in grams? I Saw you used around 250 watts , so if you can let us know the final dried weight that would be useful thanks.

That's because the gavita in those charts is hung 36 inches above the meter, QB's need to be within 12 inches to get similar levels to a gavita hung 3x higher. Take readings at the same height and the gavita would crush these QB's.

28 grams to an ounce. 9.5 ounces.... I wont spoil the fun of doing the math for you.

If that's true he is getting less than i do from a single 315 CMH. 9.5z x 28 = 266 / 246 = 1.08 grams per watt , but one would think for how much work , and how much talk there has been he could at least out yield a premade bulb unit?

And wtf would the point of that be??? In practice can you put a gavita ~12 inches from a plant without burning it??

Its like comparing apples to oranges, but saying if you hold them all at the same height, they are all bananas.

Dude, if anyone believed anything you have said in the past, he would have ended up with roughly 0.0 ounces...

You dug your grave weeks ago, give it up man.

Don't compare numbers that are taken at different heights, it's like comparing apples and oranges, QB's need to be nearly touching plants to have any type of power, totally different than a 1kw gavita which can literally be hung feet above and cover to the floor.

Nope , just had literally crap coverage, boards were so damn close to those plants lol plant couldnt grow more than 3 foot tall cause it had shit for light, that's exactly what i said, he yielded about as much as i did when i bought my blurple lights back in 2008.

So let me get this straight, its only "fair" if the lights are hung at the same height???

So why dont you run a grow with a gavita and QB setup each hung at 12 inches off canopy and lets hear the results...

Or would it only be fair to hang the QBs 3 feet from the plants like a gavita???

Does this help illustrate how stupid and pointless your argument is???

Whats your setup for your CMH and how much did you yield?

@Yodaweed and whats the advantage of hanging Gavitas so high/so far away?

Shugglet · Feb 28, 2017

@Yodaweed also, do you know what the inverse square law is???

If so, how does it make any sense that hanging a light further away would be any way shape or form, more "optimal"?

Unless you count the merits of light spread, in which case your argument loses even worse in this case.

Inverse square law is actually working against the QB's because they spread their light source out, the single bulb produces a much higher initial value , hence it can be hung higher without so much diminishing returns. QB's might be ok for a scrog type grow , but to grow a big tall plant, that's not what these are good at.

I might be buying some of these to replace my t5's and blurples i use to grow lettuce because they look like they would be good in a tiered system with height restrictions, but in my main grow area i want my lights high and powerful.

As for the CMH question i use the prism science ballast in a phantom vert reflector 4k bulb for veg, 3k bulb for flower all organic ROLS.

Bigger footprint, each light can cover a 6x4 area and grow huge plants that yield 3 pounds per light. Several people i know use the 650/750 flex gavitas instead of the 1kw and they love them.

whats their umol/j ? and arent they 750 dollars? tonnes of hot air is expensive to shift too, right? im a tent grower and dont know anything else

Heat is always the same the only thing that matters is how many watts in, if you run 1000w hps it's the same heat as a 1000w qb build. That's called the first law of thermodynamics.

Watts to BTU/hr conversion table
Power (watt) Power (BTU/hr)
1 W 3.412142 BTU/hr
10 W 34.121416 BTU/hr
100 W 341.214163 BTU/hr
1000 W 3412.141633 BTU/hr

They have a PPF of

PPF:>2000 μmol/sec

And yes they are expensive because they produce a ton of w/e is grown under them.

yeah but id need less QB watts because theyre a shit tonne more efficient.
i am a newb tho so im gna back away from this. pretty sure someone much more knowledgeable will be along shortly.

@Shugglet @lukio i thought you guys were talking to yourselves for a sec lol. Don't stress the theorycrafters and people second guessing. The boards do what they were designed to do, grow plants. now on my second grow I'm glad I don't have 600w of heat to contend with humming along. I'm ruined on grow lighting now and nothing else interest me, I'm done and moving on lol.
