DIY with Quantum Boards

Saturday... Getting crowded over here.

3x3 tent :
4 panel with COBs ( 3500k all )
320watts current dim
Plus 90w G8 red led
12/12 on wed.

Mephisto TOOF Decay ( auto )
Gorilla Glue ( reg freebie)
Blue Dream ( ( auto )) ? ........ Seed from last BD HSO auto harvest

WELP .... Had to do the flip all because the Mephisto really only sexed and didn't really change in the last week. I had to go 12/12 for all because of that , even though the gorilla is really looking like a gorilla . The BD is just gonna go with the flow.

The TOOF structurally is a nice looking plant ... I like how she branched and shaped herself. All the plants really dig the red . So maybe the next build may include a strip , or the one from RapidLed.

Dr. Earth all the way still with MaxiBloom once transition is done.
They are getting a bit full in there so I need to cut down some other plants under the other quantum in other room so I can at least pull out the gorilla. Figures crossed ... Lol.



These are the S5 bin boards and they are still killing it.

@Stephenj37826 @robincnn Does the email me when in stock feature work from the website ?
Also how long till QB288 3000k boards are in stock ? I thought with them being made in the US they wouldnt be out of stock anymore or maybe i misunderstood.
I still need about 27 more boards to finish my current project. Would love to be able to grab those within the next week or two

Without searching the whole thread, 2 qb304 in small 2x2x2ft cube, how many watts should be ran for veg?

2 qb304's in that size a space is so much overkill imho I would use 1 at 50% then up it a bit per day

No plants in there yet but testing the temps at 80w, may turn it down to 60w, mainly for starting plants to about 12 inch’s tall. Thanks

starting plants don't need to intense a light just lots of humidity

I know but this is what I have,that’s why I’m asking what power lol, so 40w? 50w?

50w will be ok to start, then turn up slowly and check how they respond if cuttings leave it at 50w for about a week before upping the intensity.

mother nature doesn't "baby" c3 seedlings outdoors...........if you want to save electricity in veg under artificial lighting? different discussion

Question; I recently bought 2 288, I'm running them in series with a hlg240-c1050 driver. I'm only getting 145 watts total. I have 304qb set up the same way and getting 300+ watts.
Are the 288 and 304 that different? Or maybe I wired it wrong?

288 is a 50 volt board... 304 is 100 volts

Ah, didn't even consider that. Shit! Oh well, it's only for vegging a 2x4 area anyway.
Thanks Dan

Sure, but the sun IS at a lower angle early in the season, meaning more shade, later sunrise, earlier sunset, and therefore less light overall light. The light levels only increase from the seedling stage until the solstice.

Running each board at about 60-70W will give you 30-35W per square foot. I would not go any higher than that.

For that small of a space, I would do 4 QB120's (or QB-132's) at 30W each, that would give you beautiful even coverage.

Thanks but I have the lights already, 2 boards on a 185-1400A 185w max at the walk.
May get a talker tent to veg in anyway

Depends when you sow, lol....... still comparing the giant star vs indoor lighting ,c3,c4,cam seedlings will acclimate to it.

Moving indoor plants to outdoor is another matter.

nfhiggs said:

Umm.... that's a 50% increase in the number of boards, diodes and power. So why on earth would you NOT expect a 50% increase in light?

Exactly why I am no longer engaging ccc fucktard.

Clearly, this dude is Trolling because no one in their right mind can be that stupid

Hey everyone ran into a problem with my 4x 132 set up. This morning I noticed one of the boards was no longer lit and the others were dim. I proceeded to check all wiring and even changed out a few, but with the same result.

Upon switching the order of the boards the same board would not light. There are no signs of any sort of damage so I’m not sure what to do.

I originally ordered these from amazon and it says I can no longer return the

Thank you

I know these aren’t cannabis plants but hey they are still grown from seed under quantum boards.

Tomato and pepper plants getting ready for planting outside. Being fed MegaCrop. All seed saved from last year. The heirloom tomatoes are from seed I saved from my little girls tomato plant she grew at school last year in kindergarten and brought home in a styrofoam cup at end of school. Same heirlooms I grew at school over 30 years ago.

2 QB304 3000k running at 184 watts at the wall.


2 QB120 4000k running 70 Watts at the wall.
