The Uvb "testing" had elevated levels of thc and with that goes cbg, maybe more of both regardless of stage in late flower, kinda like taking the original thc/cbg curve and bumping it up. What would be interesting is figuring out the ratio of cbg to thc for non uvb versus uvb. Is it higher in both percentages by the same rate or is cbg taking more of the ratio? That would tell us something I think.
I also focus on producing the most photons at the lowest cost for my users.
This is not correct. CBGa is the precursor to all of them, including CBG. CBG is not a precursor to THCa or CBDa: https://www.sciencedirect.com/topics/neuroscience/cannabigerol
While no-one denies photons > spectrum, it is the spectrum that is responsible for photomorphogenic response in plants that determines how they grow, as well as how they photosynthesise. All things being equal, efficiency comes first, but if you can have efficiency as well as encourage correct growth, it can have a compounding effect on efficiency.
I wonder if the cure process is heavily dependent on cbg breaking down. The old adage that a good cure counts for 50% of the quality. My reason for this is cbg boiling point is at 52C and like a pot of water at 60C it evaporates faster than a pot of water at 21C. cbga is converted by the plant into thca, cbda, cbga and all these degrade to non acidic form with cbg degrading quickest. Maybe the reason for burping or offgassing jars, or getting rid of the cbg gas. This might also explain weed getting stronger with a good cure, cbga converting to cbda or thca. Just a theory.
A long removed relative of mine William Crapo Durant started Chevrolet GM and Frigidaire. Chevrolet was started to compete with the model t, ended up a popper with the stock market crash he lost it all.
OK. I should have listened to you then. LOL! There seems to be some confusion between CBGa and CBG but I'm glad I had it right to begin with.
If I read this right the enzymes turn CBGa into the precursors THCa, CBDa and CBCa, which in turn decarboxylate into d9THC, CBC, and CBC. CBN comes from oxidised d9THC.
I think you mean "fucking analogies"
I agree, but in nature, few plants have EVERYTHING 100% perfect... no one comes around to make sure that the soil has just the right nutrients or that some tree doesn't grow where it steals a few hours of daylight. What you are aiming for is noble, but hopefully, the actual cost of what you say isn't doubling the cost per foot light up a place..While no-one denies photons > spectrum, it is the spectrum that is responsible for photomorphogenic response in plants that determines how they grow, as well as how they photosynthesise. All things being equal, efficiency comes first, but if you can have efficiency as well as encourage correct growth, it can have a compounding effect on efficiency.
Cost is another factor altogether and while again, no-one denies bang-for-buck drives the market, the cost of LEDs compared to what cannabis sells for even in legal markets makes it worth pursuing the best of both words (efficiency and spectrum) ahead of cost (to a point), IMO. It is horses for courses, but if we didn't have high-end manufacturers setting the bar (think BMW/Mercedes/Porsche etc), then the low-end manufacturers wouldn't be along for the ride (think Hyundai, Kia etc). The economical cars of today are far more luxurious than even the luxury cars of yesteryear . . . but those luxury cars had to come first. It's how we got multi-valve engines and auto transmissions. You get the idea and I'm going off on a tangent
You're right. If anything, indoor growing teaches you just how adaptable plants are. I still use a 2'x2' F-Series strip-frame build in my veg tent because it just works – there's really no need to get rid of it. But – and take this with a pinch of salt – when it comes to flowering, we're seeing High Lights beat the Samsung-based boards both in terms of yield and quality, so I won't be going back to LM561Cs any time soon. To me it would be a bit like going back to HPS (not really, but it would still be retrograde).
But here in Australia you can buy two 450W High Light kits with heatsinks and drivers for the price of one HLG-550 and not only get much better coverage, but up to 900W with arguably a better spectrum, better quality board and guaranteed better yields (by virtue of the fact they put out almost twice as much light over a greater area). So it's really not that much of a stretch.

Of course, you would expect me to say that.
Hey @ANC ,
growlightsaustralia.com
MH user over here. Tried and true smells and stickyness!We do have spectrographs of the CMH on its own and mixed with the High Red boards.
CMH (2x 315W)
View attachment 4530265
CMH + High Red @ 5:2 ratio (630W of CMH, 240W of LED)
View attachment 4530267
These CMH lamps have a very good spectrum already and are proven performers, but the High Lights do add a bit more red and also fill in the gaps. The grower says he has had better results since adding LED to his grows.
On the subject of further tests, we do have those areas covered – but thanks for offering. The grower above has just bought four High Light UV boards with heatsinks and two 320 drivers to run in another tent, so it should be a fairly even test if we can get him to run just 630W of CMH and 640W of LED. We will definitely be able to see the difference between CMH and near-UV grown under the same conditions. That will be the real acid test for us, as CMH seems to be the industry standard when it comes to cannabinoid and terpene production. That's what the CMH guys keep telling us
Have you done any cannabinoid testing in your grows? If so, have you seen much of a difference in your grows since using LED?
Hi Prawn...yeah I like cobs they are easier to move and angle in a tightish space.. The light in the center is a 105w OpticLED Phantom XL Dimmable..(my latest addition) its ppft is higher when you remove the clear cover, but its great regardless ..but for me it keeps the leds clean and isnt nessesay at the moment... -STELTHYCool set-up mate. It's a bit ghetto but I like it
What's the circular LED fixture in the middle with the white mid-powers and red, blue and far red monos under a heatsink?
I am interested in the ones around the sides....?? - STELTHYHey @ANC ,
Are you asking about the High Light UV boards or the Buddies stuck to the side of Prawn Connery's tent?
