Quantum Board Numbers.

[G.V]

@sixstring2112 Thanks very much for that, great stuff.

What are the plants like down the stem, are the buds as good below the canopy top as they might be with traditional lighting?

 

[Stephenj37826]

Are there any official good quality meter readings for the Quantum boards yet?

I've been trawling through the site for a while and although I see some on page one of the main thread, I cant find anything solid.

I really like these boards, but my grow room is a little larger than a 4x4 foot tent and so far I'm really struggling to see anything more than a 4 board grow with a few plants (absolutely no disrespect intended), and even then the details can be very grey.

I understand the QB's are in their early stages, but there must have been a few fully finished grows with more than a few plants surely?


To invest in this equipment people will need facts, numbers, and to some extent assurance. I understand that a 2 board grow is an easy thing to gamble with. But what about those of us that might need to replace 1000w lamps or cover 10 x 8 feet areas?

Why would I fill my room with Quantum Boards over CMH or 1000w DE?

I am in no way being negative, if I though the tech was in any way not right I wouldn't be here typing. I have maximum respect for the chaps at HLG / NGL, and I believe in the technology, been a fan since the go with LED's.

If anyone has some serious stuff to show me with these Quantum Boards please please do link me up with some grows, buds, numbers.

Many thanks and happy growing.

They have been Sphere tested. The numbers on the website are labratory results and thus as accurate as you can get. The estimated ler qer is also from a radio spectrometer. We say estimated as it can vary from different testing equipment but it it's within the margin of error of less than 2%.

I had seen these. And I say this with all due respect for HLG, but Estimated leaves a lot of open ground.

I cant take an estimated number, from a single (unknown to myself source) and then use this to make a well judged decision on making a $3000 investment.

LED's don't have IR or UV like CMH lights do, i'd go with CMH if you are looking for quality and quantity.

Or add an agromax UV bulb.

and for all the red light these lack?

 

[zypheruk]

fuckme here comes the retard

and for all the red light these lack?

As a supplement to the LED.

 

[qballizhere]

Its easy to add 660 nm and 720 nm leds if you want them

and for all the red light these lack?

This is really good to know, Thanks for this.

Take it easy folks, I don't want to turn this into a debate on which is best. For the record I really like CMH technology, it is without a doubt one the best sources of grow light in the world.

But spectrum and light figures aside its those end numbers I'm after. Weight, bud density etc.

Don't matter how much of what the light has or don't has.... Top dollar light with gizmos and all manor of shit wont make a good grower. You could get nasa to design you something that would grow weed on the moon, you got shit genetics and a piss poor grower it wont help zilcho.


I just wanna know they're going to give me some fat chunky buds like my HPS do, I don't much care if they a million umol and made of 24k gold.

 

[G.V]

That said if @robincnn or @Stephenj37826 can make one that plays Vinyl I would really appreciate that

There isn't too much evidence it will get you much more from your crop at the moment, so I cant sove aside QB's for CMH based on a little extra Red and UV.

Unless you got me a nice link to something telling me I'm gona get another 10% of buds from some UV2?

 

[G.V]

fuckme here comes the retard

Is it like that? lol

 

[zypheruk]

@G.V not calling you a retard btw. lol

http://www.eyehortilux.com/blog/post/the-benefits-of-uv-light-for-indoor-plant-growth

from that article

"UV light activates a plant’s natural defense mechanisms, producing a sort of “sun screen” to protect itself from the damaging light. Some plants can produce as much as 15 different defense proteins with exposure to UV. As the amount of UV increases, so does the production of defense proteins. The presence of these proteins can enhance a plant’s smell, color, taste and resistance to disease. Plants grown indoors without exposure to UV can lack these enhanced benefits. - See more at: http://www.eyehortilux.com/blog/post/the-benefits-of-uv-light-for-indoor-plant-growth#sthash.aHasxVI9.dpuf"

Then there is this article published by high times

http://hightimes.com/grow/grow-hack-how-to-use-a-uv-lamp-to-increase-thc/

From that article

"Cannabis researchers in Maryland exposed pot plants to ultraviolet radiation to see what would happen. They found that increasing doses of UVB radiation, a natural part of sunlight, made the plants produce almost 28% more THC in the buds."




So , 10% is definitely doable, you can get over 20% increase in THC production. UV light is essential to growing proper cannabis.

you can ask here all you want, but it sure make a lot more sense to go to the source don't you think? These guys sell commercial lights also, so the must have the answers your looking for. 20 boards@ 90 watts a board would be 2090 watts you sure aren't light that space with just 2 DE's........ and double the yield? possibly, but what about reduced heat and electric consumption? I think your looking at this all wrong

I need 20 Boards to run my room.

To be truthfully blunt, if I add any more boards the consumption would go through the roof.

Again I say this with honest intent, but what good is using more watts than HPS?

I understand the umol / Par might be double from the QB's than HPS or even CMH. But until someone shows me double the yield or buds the size of oak tree trunks I will stick with lower consumption as my key interest in these.

I'm honestly not here to rain on any parades, just to get as much info to make a wise decision. As I said I really like these boards and would love to have them lighting my next grow.

But on the other hand I'm a very cautious fellow.

I believe he has 5k hps now since he said 4 boards per light and he needs 20 boards if im wrong please say so

Though phosphor LEDs do actually produce IR.

90CRI LEDs actually quite a bit.

And as I've said, supplemental UV isn't hard to add.

They have very little IR , their spectrum falls off a cliff after the orange spectrum. They have near zero spectrum past 730nm and barely any between 700-730nm. Even the 3k chips.

Nothing like the huge bump of IR a HID light has. Still that spectrum looks good for leafy greens to me. It has so much blue in it...also zero UV light.

How much IR do you even need for the emerson effect, can't be that much since yield would be much lower otherwise.
