Unfortunately most of what you hear in the cannabis community is informal science at best and wives tales or even sales spin at worst. I have a friend who grew the same strain inside many times and outside many times and despite the total lack of UV light, the inside stuff was far better in practically every regard. I'm skeptical that it truly makes the difference often attributed to it.

Why doesn't anyone go and look for research in this on other plants?

Data on other plants can be applied to cannabis just not on THC or cannabinoid content obviously.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4240378/

Here's an article showing Basil Terp content doubling under uvb treatment.. More terpenes = better high.. and also that the capitulate trichomes do fill more completely under uvb supplementation..

If you have everything dialed in and have nowhere left to go then maybe start thinking about UV supplementation but most ganja growers are far from that level of control over their indoor environment..

I'm amazed how many people still don't know about VPD and the importance of the right humidity for transpiration.

I don't doubt it has some potential effects in cannabis, but the very best herb I've used over the years has been almost exclusively grown indoors; Most of which did not have any appreciable UV content(HPS or LED lights). I've seen some excellent bud grown under metal halide lights too of course, and CMH is even better. Still, the main difference I've seen in those cases is the density of the bud and the structure of the plants. I'm deeply skeptical of how significant the difference is, but I wouldn't say that all things equal there might not be SOME difference. Is it worth the risks and costs? I have yet to be sold on the notion that it is.

I actually went to the trouble to buy a Solarmeter 6.2 and measured the difference in a PURE UV 2' T5 and a lightly used Reptisun 10. The readings posted over at RIU months ago. Not that its science but its the closest thing I have seen linking actual measurement. Love to see some REAL testing instead of butt hurt posts by dudes who just say this or that UV light looks better to me or feels more like sun on my skin or some other BS. I cant say if it helped since I dont have room to run a side by side in different tents or such with and without UVB.
I keep asking the stoner science professors to show some info besides what they "hear" or what they think or what they "see" or "feel". I think some of them are sales hucksters most likely. I have spent real money out of my pocket to compare in a no way scientific manor and make no claims one way or another.
Cheers....So you went and bought almost the same meter I've had for years (6.5 is better for the task and certainly in units most understand easily); one that I recommended and have already posted in depth details on, sweet, what did you test lights wise, just a couple? I’ve tested over 30 sources. UVB has pros and cons, anyone using GH and outdoors to grow many plants can clearly express this. You ever see clumsy bugs/bees in a GH and wonder why, yup no UV, big part of the way they see.....

I have excellent UVB lights here (https://www.ushio.com/files/specific...blacklight.pdf - the 306nm ones, you won't find anything close to this in output for wattage or costs), safe and easy for me to use inside but I don’t often anymore fwiw. I also know my basil in my GH looks much healthier but pales in comparison to my outside grow basil for terps and flavor. Take it as u will....

good post(s) in here lost.....


In General....

funny how if you do actually go back in time to my posts and look truly you'll realize everything I've said in here holds weight, truth & value, not all of us in here are Bro science..... Bros .. probably the same for my posts on VPD, years ago, click and see
