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.Thats 500 watts to grow 150 grams......... unless you've got really cheap power, not worth it IMO.
And if it's too much right now you can always dim themAn 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.
At $5 a gram, that $750 will buy a lot of extra electricity. Just saying...Thats 500 watts to grow 150 grams......... unless you've got really cheap power, not worth it IMO.
Haha it's not too much the plants can probably handle 50w/sq ft idk why people have bleaching problems I haven't had anyAnd if it's too much right now you can always dim them
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
Love the zip ties holding those qbs nice buildHere I go again.
Cant afford an expensive meter but my plants tell me its quite a bit. Speaking of rock hard budscan 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)

(Edit) well i tried to paste it didnt come out to well.
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 sunAn 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.
pop out the black rubber plug labeled IO and use a #1 Phillips screwdriverStupid question time.
So I got the type A ballast...how do you dim?
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 defoliationThe 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
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 70sVery dense buds on this baby hereView attachment 4005483 Temp/RH-80-85/65-70%
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%.
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.So you keep your temps 80 to 85 during flower ? Do you find this has been working well for your harvests?

All 3 of mine came at 260wwhen you buy the QB kits from HLG is the driver, pre-set. or what is it at factory? can you turn it up?
