Dude, it may not seem like it, but I honestly have no quarrel with you or your desire for better bud! Seroius! We are on the same team.I'm definitely no scientist just a stoner who likes to grow better Bud each time...
Your basic bro.
I have seen a study floating around about UVA and trichome number. I am sorry I do not have more details but based on what you have seen from me if I find it you can count on it being posted here.Says right there 385nM - UVA. We are not even talking about the same spectrum.
It's killer your light is making for better bud. Sorry we are not comparing apples to apples.
Thinking about the problem of what interval of time to count photo exposure over led me to a hypothesis about why UV exposure only in the last two weeks leads to the same increase as longer exposure.View attachment 1105797View attachment 1105798
Here is my attempt to show how i am thinking about it. Sorry about the childish handwriting...i will edit with typed captions lol.
I am currently doing UVA and FAR Red testing in my other Flower tent. I will have some useable data on those wavelengths, including trichome production, in about 1.5 months. Looking forward to that.I have seen a study floating around about UVA and trichome number.

Based on what I have seen, I think the mechanism is probably different.
Standardized photos and visual analysis. It should be easy enough to train a computer to count trichomes if the image is from exactly the same angle and high enough quality. Or just get high and be very patient lmao.I am currently doing UVA and FAR Red testing in my other Flower tent.

How do you quantify number and mass of trichomes?
Interesting. I always assumed the sunscreen getting used / burned is what caused trichomes to go amber. Could be completely wrong.Thinking about the problem of what interval of time to count photo exposure over led me to a hypothesis about why UV exposure only in the last two weeks leads to the same increase as longer exposure.
The "sunscreen" gets used up over time. That effect is going to be a negative drag on whatever positive effect you get to that point. And will contribute to the UVR8 accumulation of the cell in the meantime, also a negative effect. So maybe it just about balances out.
My assumption is local as well. If it is not local, that itself would be a very interesting result.Interesting. I always assumed the sunscreen getting used / burned is what caused trichomes to go amber. Could be completely wrong.
I'm also curious on your feedback on my testing method. If I have half of a plant under UVB and the other half normal light, do you think the UVR8 response is mobile, meaning it will still result in the buds on the control non-UV side of the plant, or is it local to the bud? My assumption is local.
Again, this is the kind of thing I can try to do if you can provide the images.
Within this hypothesis, the plant is trying to keep UV-B induced protein damage and subsequent proteasome-mediated degradation to a minimum level (some minimum equilibrium rate, maybe zero or maybe there is an "acceptable" level) by managing the sunscreen level appropriately, maxing it out until it can no longer perform the processes to keep its defenses going due to senescence. So basically the cells are breaking down the used up THC cleanly and replacing it until they can no longer do it cleanly (proteasome-mediation, it I guess), and you just see the damage. The reason it wants to use THC is that the THC can last longer before needing to be replaced due to its ability to absorb UV-B because of chemistry reasons I guess.Interesting.

so long as they are comparable and we can try to account for size in various ways, it should be okay to use for data. Get us somewhere at least.I'm trying to figure this out, I don't know how to get the same pics of the same bud site repeatedly. Normally I chop off a section and take it to the microscope. I'll play around with this a bit and see if I can come up with a standard you can use. Maybe a macro lens on a DSLR at high res so you can zoom in. Appreciate the offer.

I may have no idea what I am f*cking talking about btw, this is all just in my world as I am trying to figure it out.
our little tests prove nothing but confirmation bias. ;-)
Because, to be honest, i want to. It's not a waste of time. I am purely an amateur in the original sense of the word i.e. for the love of it. If i was making money with this, i might feel differently. Thank god i have other ways that i vastly prefer to do that.In the Bruce bugby video posted on sshz’s thread (quality of light somethhe says that they are finding that regular blue light may be responsible for most of the trichrome growth.
also far red is responsible for branch elongation and it basically makes the framework for more plant mass.
Why waste time testing what a product manager selling overpriced fluorescent lamps at home when university testing is in progress and way ahead?
Even now Ed rosenthal is putting ir on plants at night to prove faster flowering. Which he suspected 30 years ago.

From my research... my opinion only is that there is much like the Emerson effect on the red spectrum, similarly there is an effect with blue and UVA/UVB. Of which the ratios are starting to be uncovered. I believe around 5-7%UVB in combination with blue (can't say the wavelength or %) works to create the increases we are looking to see. Without UV or blue we don't see the results we are looking for... a few years and the info will be proven and available as to what ratios provide the best results. This is true of any spectrum and the ratios and a lot of testing has been done to find the most ideal ratios of red to green to blue to far red to infared to UVB to UVA...
These are no joke. I just burned the crap out of a plant using one for the first time. I'm pulling up a seat for some Farm wisdom hereSolarSystem® UVB
The latest generation high output UVB T5 fluorescent bulb. This system is perfect for a single light in a tent or several hundred lights in a large commercial operation.californialightworks.com
