It can give an idea.

Although 1w does equate to 3.41btu/hr, anticipating heat is a closer estimation with some devices than others due to the different forms of energy transfer utilized to distribute the wall watts throughout the room (convection, conduction, radiation), and the rate at which the room extracts heat from the air.

In 2 rooms with good insulation, if given time for the energy to dissipate, the ambients will be the same. But real world temps depend on rates, not absolute qty of energy. We exhaust air at a rate. The room isn't a closed system. So the rate at which it heats matters.

EDIT:
You have to be careful with RIU (just like everywhere), they have some really smart fellers over there but there's a lot of unsubstantiated claims and incorrect advice. Look for cited sources or links. That's just my $0.02. I've been told things that I thought were correct by some of the big whigs over there only to find they had no clue what they were talking about. I'm not a biologist or plant expert, but I know a fair amount of chemistry, physics, electric, thermo, and math so those are the areas I typically comment on. I make mistakes and I'd encourage all my posts to be scrutinized. I only care about perpetuating truth and fact.

Right on.
Very well stated, and words taken out of my mouth. Lol.

So far the Jack herer is the star of the grow for vigor and size.
I dont hqve much of a sense of smell ,from snorting drugs for many years, but the stench coming out od this tent when I open it is invigorating!
I have the three big photos in back to go next in a couple weeks at least.
They seem to be losing color from,each evenly. I am wondering if i should,up the calmag to a full dose of 5ml per gallon.
I have one nute bucket to keep it easy for the grow bro. In truth the 5 in front were all ran 12/12 from seed behind the nute schedule of the other plants. So they were getting the flowering nutes while,in transition, if that makes sense.
It worked out well by not overfeeding the autos or the plants that were ran about 6 weeks behind them. But I am starting to see it now in the older photos.
Maybe ita time to make a buCket for the late flowering plants with more Epsom and cal mag?

By no means are these infirmary bound but I see it losing vigor in late flower when shes hungry. Whatcha think? @Opie1
 
Hey guys, sorry to jack the thread here, but I see some knowledgeable folks here, and was hoping someone wouldn't mind helping me out with a relatable question:

I just picked up a 4pk of the HLG qb120 V2s. Was wondering if I can run them in series with a driver that I already had, HLG-320H-C1400A. If I turn that driver down so not to max out the boards, would it work? Or do I need to pick up a different driver? Any help or input would be appreciated.

I can't seem to find an actual spec sheet for those boards to see what they'd run at. But yes you could use that driver.
Do you have a link or the spec sheet you could post?

Thanks guys. I only have the info that is in that link that Terpy posted. I see they recommend the 240H-2100, Giving around 47w per board. Looks like the one I have would run them at only 31w per board, but would still work? Is that right?
 
Short answer, yes. Can blast full power.

Looks like ~21V - 22V forward voltage...

LM301B only goes to ~2.88V...
CRF_Fv_Graphs_1.0.png

Trial and error, I'll guess 2.8V and see where that goes..
22V ÷ 2.8V = 7.85 chips; which is pretty close to 8, so it looks like 8 in series, 15 in parallel. 1400mA split 15 ways is ~93mA, and the LM301b is rated 180mA+. Looking at the driver you can see the 320h 1400 has a voltage range of 114 - 229VDC. 4 QB120s in a row at 22V each is 88V and well under the max rating of the 320h 1400.

EDIT:
Ya, 31W is what I calculate too.

Also I guess could have just looked at the chart they provide lol that would have been easier but I like making little pictures and stuff if you haven't noticed lol

The limitation on full power is heat. If your space can handle the warmth the efficiency is less important (imo)

But the tent....wow I had no idea of the heat containment. The efficiency in a tent is paramount. Better to run wall to wall strips or boards at 50% than to crank them and hit 90+ degrees because it screws the plants up and causes all of these weird problems you chase that are....HEAT related. I had no idea until my flower room showed me.

Cubic volume of air is weird like cubic space of reservoirs

The more you have the less it is screwed up by changes.

The smaller it is the more work it is

What I know is based on observation and research...but its got to be right :D Its empirical science ! tested by me.

Thank you, Chief! I appreciate the graphical breakdown and your explanation of it all.

I've got these boards arriving today and was eager to go ahead and frame them up and get them in this tent. The lower power doesn't bother me too much right now, as it will be used only for seed starts and early veg, at the moment. I may go back and get the 240-2100, but for now this will be just fine.

Thanks again to all who chimed in!

I correct myself. The voltage does not meet the minimum required of the driver. 4 boards is the 88v, the min of the driver range is 114v.
You'd have to add two more boards to hit that #.

Yes 31 watts if it met the V range of the driver.

I like pictures too. Lol.
The V range is not met though so it likely will not fire the leds.

Well shit, lol. That makes sense, though. Thank you Jesse.

Looks like I will be ordering that other driver after all.

Does the 240H-C2100 seem like the best option for just the 4 boards? I've got 2 qb324s here not being used, but pretty sure I can't mix them and wire those 6 together, right?

Yes, you could add the two others, so all 6 on the 320 would work. Be a nice low wattage though, good for low heat and high par. Cant find a data sheet for the qb 324's to confirm their wattage at 1400 ma. But based on the 288's specs it'd be around 70 to 80 watts. So call it 2×80 + 4×37= 308 ish total watts. And a rough total of 184v with all 6 boards.
The 240h-C2100 would not run all 6, but would be good for the four qb 120's.

Yeah, I don't know what's up with them not releasing a data sheet for that board. I could be mistaken, but I think that the qb324 is closer to the qb304, than the qb288. With vdc being close to 110v per board at 1400ma, vs 48v on the 288s.

If so, that would bring the total vdc of the 6 boards up to, or just over 300, which is the max rating for the molex connectors. Does this sound like cause for concern? What if I just ran one of the 324s along with the qb120s, would that be a better option? I don't need a ton of light or power in my situation. It's going in a 3x3 tent, just for seed starts, clones, early veg, etc.

Wow, didn't know they were 110v. Just one of those bad boys with the 4 120's would make it then.
154 watts out of the 324 qb by the math, and 148 from the four 120's. The 320 would work.
It would not though with the second one added. And you are correct, don't overload the Molex connectors. They can probably handle it, but risk of melting and or fire ain't worth it.

How old is your qb324?
