can someone out there take a PAR reading or map the PPFD from the qb 288 or 304 ran at 500ma or even 700 ma ?
I pasted a copy of this saying 3.02μmoles/joule.
Would love to actually see what a meter is saying.


Voltage (Min Vf dc) Voltage (Max Vf dc) Current (mA) Watts at Board (Min Watts) Watts at Board (Max Watts) Max Lm/W at Board (40C) Min Lm/W at Board (40C) Min μmoles/joule at Board(40C)
47.7 49.5 500 23.7 24.5 207.4 200.1 3.02

(Edit) well i tried to paste it didnt come out to well.

I'm running 4 QB304 at a total of 363 watts from the wall. All I have for an extraction fan is an 8" duct fan. My 4x4 tent is 10 degrees cooler than it was with a 345 actual watts Vipar piece of crap. Sounds like you don't have enough air moving through the tent, and if the tent is in a room without air conditioning, the room temps with ANY light will gradually rise as the heat builds in the room

Thanks for the recommendations. So soloution seems to definetly drop a biger oscillating fan in there for more air to move about and cool the actual room that its in. Is that correct ?

Quantums work well with " Others " .....

I put up a G8 Deep Red light ( 630-660nm ) as a supplemental to my QB rig -
I have 3500k spec and figure more red is good thing ... So if you got some old gear laying around you can shake it up a bit. G8 throws pretty intense red for what it is ... Especially when main rig is off ... It looks like a German whorehouse in there. ACHTUNG BABY !

Even though quantum doesn't need it ... I really didn't want to sell those G8 I got ...
Tangerine Dream had some fertilizer issues ( my fuck up / I fed twice *facepalm ) but she still trucking along ....

Deep red .... Hmmmmmm @robincnn and @Stephenj37826 ....
Imagine if you will a 60W or 120W full red bloom light ..... HMMMMMMMMMM

Cant afford an expensive meter but my plants tell me its quite a bit. Speaking of rock hard buds

An extra 150g would pay for electricity clones and soil for the whole grow that's pretty worth it. Plus if I get a bigger space I just spread the lights out more win win.

The more qbs the better can always dim them. what makes it really great is so many points of light over 2700 diodes is alot of points of light can see that making huge gains in lower canopy like im seeing but 9 at full blast would be insane to look at be like looking at the sun

I don't really see a point in dimming unless temperature gets too high but even during the heat wave it only hit 90 for a few hours. Ya it's stupid bright! light makes it all the way through the canopy even before defoliation

got home today after a 5 day little get away

Just wanted to report back; I swapped out the pot this evening with one that measured out just over 100k, and we're up to 260W at the wall! Yeah science!

Meanwell type A usually gives more power than type B. HLG Kits come with Type A as standard
HLG-240H-CxxxxA will go as high as 280-300 watts.
HLG-240H-CxxxxB will be max around 260-270 watts. A 100K pot will limit it to 100%. However pots have +-20% tolerance so a 100K can be as low as 80K or as high as 120K. For max just leave the Dim + and - Open then it gets around 105%-110%.

So you keep your temps 80 to 85 during flower ? Do you find this has been working well for your harvests? Do you do this for veg and flower? I keep reading on other sites to keep the tent in the 70s

Really those temps are due to limited capacity to control. 2 cabinets in a hot shed. Window AC does what it can. So I try to follow VPD range and run overkill exhaust/oscillating fan.
My first harvest with QBs went great. Super dense buds curing, had to make room so got pulled atleast 3 weeks early. Dense all the way down, no popcorn. But i'm convinced heat and lack of experience makes low trich count. I'll dial in the strains I have to see, by then cooler temps will be on the horizon.P1030158.JPG
