Question about IR\UV "reinforcement"

That's not what it says and you haven't had enough time to educate yourself by reading the whole study.

Let me say this one last time. I’m going off lab study’s on cannabis with uva and uvb and individual without one another

I’m ALSO USING THEM. And what iv seen and noticed is an exceptional difference in the thickness of stalk and bulb. Much larger and filled out. Compared to me not using it over the past. I mean. It’s a complete difference to the naked ey

Are you using them currently?

I don't see the point in continuing this conversation.

I’m not wasting my time on reading what uv does. I know what it does. I want exactly what I asked for from your point. Lab results of cannabinoid content vs not having it Like I said. I’m looking for a reason NOT to use it.

Bye bye

Maybe you should try reading the whole study. This what real science looks like:

Cannabis Inflorescence Yield and Cannabinoid Concentration Are Not Increased With Exposure to Short-Wavelength Ultraviolet-B Radiation

Before ultraviolet (UV) radiation can be used as a horticultural management tool in commercial Cannabis sativa (cannabis) production, the effects of UV on cannabis should be vetted scientifically. In this study we investigated the effects of UV exposure ...

Kudos for finding the full text.

Skimming thru it theres a few things that stand out: the description of upwards turned leaf margins/serrations as the first sign of uv treatment: most people would recognise this as uv damage and know to turn it down or to shorten the interval. While i recognise i havent read it all i dont see this as some kinda end all study re uv: it shows that if you punish your plants with uvb and when they start suffering you continue giving them more uvb (and that little bit of uvc included in the left tail of the spectrum) then your plants are not going to perform. Also it goes on to generalize regarding cannabis when they only tested two strains (that i never heard about).

My point. Uva and uvb being used correctly. Together. I’m not an expert. I just nerded out for a week on study after study. From gradually introducing uvb at 15 min per day till leading up to 2 hours. Or even just blasting it for 2 hours a cycle from the jump. I did 30 min for 2 days. Then just jumped to 2.5 hours. But some plants “fry” easier. This is why they recommend 15 min a use at first to see the plants response. Imo. It takes common sense to use something they use in a tanning bed.
that’s what I took into mind before using mine.
Nobody spends 12 hours in a tanning bed. Lol

could it be that the strain might have something to do with it??


thanks everybody for the answers, I also tried to read as much as I could over the web and came to a conclusion that I am going to try a UVA & UVB lamps.

can some one please direct me to a good source to buy these lamps?
or maybe how can I learn to choose between something fake and proper UV lamp.

Thanks again everybody for the answers. once I will manage everything I want to start a log and let you know about the process, maybe even with some pictures, might even do a side by side comparison.

@jimihendrix1 Knows a lot about UV, if he doesn't mind to step in and give some advice. He gave me a good suggestion for the Solacure light.

Personally i believe UV helps, but it needs the right amount at the right wavelength. Even if it doesn't help with THC, it surely helps to prevent mold in flowering. If anything, i would use it a non-toxic fungicide in flowering. But it surely helps with THC, i've seen some pictures and videos of plants grown with and without UV, and those with UV had much more trichomes.

I have read strain affects the outcome. Strains that evolved in places where there is higher UVA/B have the most benefit.
