What is this pic about.
It looks like UV light, but what were you doing?
And how (if) would you work with UV light to prevent bud rot?
I know handheld devices exist. But with something that can stick around 24/7.
That pic is me using an earlier version of my UV light to highlight the only case of mold on my buds that I've seen since October 2019.
And that bud got it in the drying area, it didn't have mold while it was in the grow area.
To me it means there are spores in the air but the grow area doesn't foster their growth.
Just get a blank MCPCB, or as cannabis growers know it, quantum boards, and install some 280nm LEDs on it.
Mount it how you would mount a quantum board. Mount it where you want the UV to hit
You can add other wavelengths if you want UVA as well.
There's research supporting increased resin production with UV.
Forum members also support this claim.
Broscience? Maybe... but we know it kills microbes.
Even if you don't get more resin, 280nm kills e coli at 70% of peak effectiveness of 265nm UV.
This means it just needs more time to do the same job.
How effective is it against mold? I don't know.
Is it more effective than x nanometer UV? I don't know.
But I know you have it on long enough and stuff gets dead.
I've ran these anywhere from 15 minutes to 3 hours a day depending on how hardened the plants are.
That's 3 hours of killing stuff that's in the air, on pots, soil, leaves, etc.
Even if you don't kill all of them, you're likely to be killing significant portion.
This means it takes longer for them to reproduce to levels that will overwhelm your plant's natural defenses.
Maybe even never reach that level.
Your filter only kill what gets sucked into it at 30CFM and it uses 35 watts of electricity to do it.
Typical 4x4 air flow is like a couple hundred CFM?
You need over a couple hundred watts to cover a 4x4.
And once a spore has landed and stuck its not getting sucked into the filter so you can't touch it and it starts to make more spores.
40 watts of UV LED will kill your plants and whatever microbes growing on them, so you will never spend than that on electricity.
Just ramp up the exposure slowly.
280nm UV
Kills microbes, stimulates resin production (probably), uses less electricity.
I rest my case.
