Quantum Board Yield

[hotshotisdashit]

Now that the qb's are the next big thing I have just a couple of questions from someone who's grown with them. I've heard that efficiency with them are equal to or even better than cobs. But my question is how do they stack up in the yield department. Do they yield less than, greater than, or about equal to cob yields? All are welcome to chime in even if your answer is just an assumption.
Thank You...

Better question would be... how much popcorn shit they produce in comparision with COBs?

Are you saying that qb's really only produce popcorn buds? Why do you say this?

 

[KonopCh]

I posted question, not answer to you.

I think the key to QBs is to using optics with them. sure someone will post pics of current/past flowers

Limited with experience as far as the QBs go as I have only had the one run full complete and only on 4th run of Cob grow which will be harvested within a week. But the QBs are very intense. My first thoughts were the buds were slightly bigger under the QBs and very dense, lower down the buds were better than the cob side. The QB side the colour of the buds came out slightly more noticeable.
I have to point out that there is a spectrum difference between the cobs (3500k 90cri) and the QBs (3000k 80cri) also there are differences in plants size and shape due to slightly longer veg times under cmh. So this is not an accurate comparison.
Yield wise the QBs pulled slightly less weight but those plants were slightly smaller to start with and less wattage. They do yield very well. I will know more in another 3-4 crops which I prefer but I do like both sides of my tent.

Here is the only pic I have of the last run on the QB side. Due to the intensity I had light burn on the leaves, should of kept my lights higher. Pics terrible I'm afraid.

Non on the QB side but canopy was managed better than the Cob side. Properly managed all buds should be solid but the same can be said of any light. Its just knowing the point which lowers are pointless and keeping a canopy which isn't impenetrable.

 

[VegasWinner]

Are there any lazy gardners like me that don't raise lower lights and just trim up the udders when you remember or feelin it like more clones are needed?
I would be genuinely intetested

 

[coreywebster]

Yep. Too often. I usually raise my plants but its easier to say lower my light, truth be told the lights stay in the same place because its difficult to move lights about in my room.

 

[hotshotisdashit]

Thanks corey. Your input is invaluable.

Do you find that plants syay shorter under cobs or boards?

 

[InTheValley]

probably need another year before the verdict is in.

 

[InTheValley]

Im personally hooked on the 3W-5W diodes myself. With lenses, they are awesome. I think cobs, several over the area or 1 per sqft would be great,

Im currently going to build a LED strip rig, tryin to get close to the Quantum board output.

Ive seen a couple grows with strips, but mostly mid process, and currently fired up to see GrandMaster Levels grow he currently has going. I think his test run will be the tell of how they truly do..

 

[coreywebster]

Not really, but currently my cob side was over vegged and my QB side was under vegged, trying to fill a gap In my perpetual.
But because I veg with CMH I'm not the guy to properly answer that. All I can say I'm not seeing much stretch under either cob or QB when I flip. Probably due to the kelvin of my CMH been close to both the Kelvins of my flowering lights.
@zypheruk would be able to tell you more about the QBs, he has more experience with them than me. I think he may have vegged with them.

I've heard that efficiency with them are equal to or even better than cobs.

identical phosphor white technology. which is more efficient depends on the current you run them at

Do they yield less than, greater than, or about equal to cob yields?

depends how you use them. how hard are they driven, how uniform the light is to your plants. same with two differnet size/brand COBs

Better question would be... how much popcorn shit they produce in comparision with COBs?

again its entirely how you use them. either technology emits photons of similar spectra and directivity, how you get that to your canopy at the proper intensity is in the growers hands

probably need another year before the verdict is in.

i dont think there will be a verdict. differnet people with their different growing styles are going to do well and not so well with either and prefer one over another based on how their room is setup.

they are a lot more similar than different. if the appropriate number of cobs/boards are used to make a match so they are the sam efficiency, in say a 3x3 tent 8 small cobs/4 large cobs vs 2 boards, lets say neither has optics. at 18-24" below the rig par readings will be nearly identical and yield identical results

Im personally hooked on the 3W-5W diodes myself. With lenses, they are awesome. I think cobs, several over the area or 1 per sqft would be great,

not sure if you like the 3-5W diodes for the colors or for the size, but smaller cobs like clu038 and the cheaper clu048 would pretty much destroy any of those on efficiency when run at 10W a chip, and there are all kinds of lenses for them. a bit more expensive per watt but prob 50%+ efficiency gain over most 3-5W monos.

When you say efficiency do you mean more lumens/Watt? I ask because a lot of people talk about efficiency but it can mean slightly different things to different people, depending on their way of thinking.

 

[CobKits]

lumens/watt or PAR/watt same difference when spectrum is the same

 

[StonerCol]

lumens/watt or PAR/watt same difference when spectrum is the same

Thanks for the clarification dude.

 

[InTheValley]

Oh, with all due respect, I have only used mono diodes and CFLs, lol, sooooooooo, take it for what it is.

But so far, its the best ive used thus far,

BAHAHAHAHA..

But like i said above, Im trying to replicate QB theory by building a rig with a bunch of 5630 diodes, (1440pc) although probably bottom bin, *shruggs Ill be using 2x more light then needed so that will make up the quality factor i suppose to an extent.

although i do expect a 50% drop off of advertised hype of the LEDs, for the price, i have to give it a test run.

I want to see light hit the soil. With my hacked Light, Im getting buds at 50 inches from light.

 

[InTheValley]

I see efficiency measured on the GPW dryed model. We know you gain POWER efficiency thru less heat produced, less heat to move out of the area, less AC. just as stripping and defol make the grow more efficient due to less humidity.

So like StonerCol said, different efficiencies.

I think what matter at the end of the day is, produced fruits of weight/against Power used to finish.
