DIY with Quantum Boards

[WeedSexWeightsShakes]

Honestly don't get a tower tent. I got one and regret it. Should have got an oscillating wall mount fan. The tower fan takes up too much room cause you need your ladies away from it a bit or they get wind burn. I hung mine upside down so it is a little better but I feel the wall mount fan would have been better.

Really? Are you referring to room temp or tent temp. Thanks for your help

Tent I guess why would room temp matter?

This for all of flower or can they be closer after a few weeks into flower?

Like 12in away is fine in flower

When will the 24x 120mm pin heatsinks be back in stock, thanks.

I was looking at the Chilled systems and I was wondering if I should add a UVA and Far Red supplement light to my quantum boards?
And if so (due to a tight budget) which one first?
Also is Robin planing to add some diodes to his future boards?
I love my quantums but I have noticed that the buds don't seem as dense as with my CMH bulbs any suggestions?

How many watts per square ft are you running the QBs at and the same for the cmh.

my QB is running good, its keeping up with the cxb's fine.

my only thing is: its hot, I wish they had an external driver kit, just a extension with two connectors. maybe as an option.

Yes they get hotter than 5p300s but the light output is insane lol.
Glad I got a bigger exhaust fan than I needed.
Can't wait to see the ladies when I get home Thursday.

density has little to do with uv and far red and just about everything to do with ppfd

how many watts per square foot were you running with cmh vs qb? how hard are you running the qb? how uniform is your light distribution across your canopy when checked with a lux meter or phone app?

 

[SoOLED]

"Fluffy" or Larffy flowers IME, has nothing to do with light. I came
From SE-HPS to CMH+cxb and just CXB alone. I only notice from strain to strain. These are rock hard, have seen nothing but 3500k CXB. That kind of problems for me happen when my enviro gets bad.

 

[PopeyeSpinach]

Why do they not make a 2700k board?

Very dense buds on this baby here Temp/RH-80-85/65-70%

I have a 2 slate setup for a 2x3 Scrog running at 245 watts -I have 1 QB288 and 2 QB304s like this the CMH is a vert set up but using the same size scrog but I am running the dangerous 400 watt bulb that is unshielded. I don't know maybe it is the strain I have only grown some Greenpoint seeds under them and all the others were strains from other breeders. I don't have a lux meter and just downloaded the app (I am in dark cycle right now). I bought the reflectors but have not put them on yet maybe I will add them tonight.

BTW will you be stocking the QB120?

Cobby does QB.. Sounds like a porn flick. Not that my eyes have ever seen one.

I am starting to think it is a phenotype issue, my strains from cuttings are much more dense then the majority of the Greenpoint strains that I am growing BTW nice garden.

Great news!

If I'm running 3x 304 boards... I'm a bit lost on drivers. Can I drive it with an hlg-320-48a in parallel? Or should I be choosing a constant current driver?

I think I answered my own question. I actually want 3x qb288 ran in parallel on the hlg-320-48a? Correct?

the qb288s are 54V so you would want the HLG-320H-54A to run three boards in parallel

 

[firsttimeARE]

So are these QBs only made by HLG?

If so how does a reseller got em but HLG doesnt?

Id grab some but only 3500k
