DIY with Quantum Boards

[Ryante55]

Again, to a point of diminishing returns. See the graphic I posted above; the last little bit is costly in terms of both light and environmental control and doesn't return an awful lot for the trouble.

Ya I get that I guess I just don't think it will diminishing that much. Here's my logic
4x8 room 1000w let's say you have a really good grow and get 1.8 g/w that's 1800g now put 1500w in the same space diminishing returns brings you down to 1.3 g/w that's 1950g over a qp extra is worth it to me that will cover the electricity cost for the whole grow. Maybe I'm wrong but if I manage at least 1.3 g/w this grow I'll be super happy with my decision. Another reason to run more light is to add heat to the room in my space if I ran 30w/sqft I would need to run a heater to get my temps up

800-1000 is where i thought I should shoot for. And led gardener?'s video was showing 6 hundred something ?dead center 24" above.. I could be remembering wrong. And of course those numbers would go up when multiple boards are used. All speculation for me right this moment

I think that's a good middle of the road number to shoot for.

I like your logic. Clearly you've thought through your approach and you have clear and achievable goals, which is the main thing.

Hubba hubba...

Le Grande Tetons!

Thank you for the details! I didn't realize the kit came with a dimming pot, so I bought some extras beforehand, and sure enough some of them measure out a bit below 100k. Good to know what's going on!

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%.

Could someone recommend a driver(/s) to run 9x QB288 with a current around 500 ma per board.
Only looking to use 300-350 max watts all together.

Would be grateful for the help a little lost with the drivers and whats required with min max volts and what not.

My god , you guys are killing me ..... " you ever get to the point where you ALREADY have ALL the lights you need , BUT YOU WANT MORE ?! "

God Damn it ...... Lol

Why not build 3 sets of 3 with something like HLG-240H-54 ( dimmable ) ?
You would have incredible flexibility among all 9 boards ... Each set to power levels of your choice or together ... Plus the fact is that you can PULL a rig of 3 and change footprint as needed .... You can dim power to lower levels easier with potentiometer control than trying to look for a particular hardwired current option. This where Quantums shine ... The power versus efficiency.... All by a little knob.

Don't Forget to add this to your BANANA20 sales code ...... Lol
( oddly this premiered 40 years ago THIS MONTH !!! - What great timing ! )

Here I go again.

Will the skull grow too? It's green...

 

[Budzbuddha]

Wellllllll ... With those nice new grows all up on this thread ... , I hit up that dude that is my seed source
( if I sleep with his sister ..... You know " Jump on a Grenade ? " ) anyways traded some candy dream beans for some GodFather OG ?.....

Good News ....
Added to the Quantum Nursery - Batwing Rig ..... 3 QB 304s 3 panel

Bad News .... Need a Rape Shower after slapping her thigh and riding the wave in ...
( thank god for Brass Knuckles Cartriges ! ) ..... *nausea

Power is dimmed to around 205w - 15"-18" ish ... 18/6 cycle
Lowe's Super Mix - tap 6.5
Dr. Earth Liquid Solution ( 3/3/3 ) - Smells like shit but primo plant food !
Rapid Rooter Plugs

More cushion for the pushin', brah!

for real, TBH I dunno if I'm offended or impressed LOL.

It's a sacrifice that must be made from time to time...

 

[pop22]

In 12 sq.ft? Overkill lol!

Or 3 260 kits and blast em?

 

[pop22]

The plants may love it, but without CO2, its a waste IMO, they are not going to out produce 30W/sq.ft by enough to be worth it.

I'm running over 40w/SF plants love it and are about 16 in away from the lights why not run more light if you can?

 

[pop22]

Thats 500 watts to grow 150 grams......... unless you've got really cheap power, not worth it IMO.
