Of course not all UV light is dangerous..theyre called blacklights. But they wont fight contamination, and they arent good for mushrooms. Basically if its strong enough to kill molds, dont you think it would be strong enough to do damage to yours and the mushrooms cells?

"So, according to what I've read, part of the reason why Trich doesn't run wild in the wild is because of lots of FAE outside, but also because of the UV light it's exposed to from the sun."

I have an open window in my "shroom room" and my tubs get plenty of indirect sunlight as well as a bit of direct every day. I have had a VERY low rate of contamination. I usually get it on tubs left alone in the corner after a cupl flushes. The ones that dont get much fae or sunlight..
I think the natural elements incorporated into my grows help me keep contams at bay. On the contrary, when I grew in closets, basements or other enclosed spaces I was CONSTANTLY fighting contams.
I also realized by incorporating TRUE fresh air I didnt have to be so sterile all the time. I pretty much mix my tubs in the kitchen, do g2g's on my counter and dont use any gloveboxes, flowhoods, etc... I know these things definitely have their place in indoor cultivation. I just dont have a necessity for them. :stoned:

UV-B Trich Experiment

Check that out guys. They use UV-B, not even the dreaded UV-C, to kill trich and stop germination entirely. "The lethal dose (LD50) of UV-B radiation for C. rosea LQC 62 was 1 hour, 59 minutes and 30 seconds and the germination did not occur after 3 hours, 24 minutes, and 50 seconds. LD50 for Trichoderma LQC 96 was 2 hours and 19 minutes and the germination did not occur after 3 hours and 49 minutes of exposure to UV-B radiation. In the second test, in which isolates were incubated, the LD50 was 1 hour and 49 minutes for C. rosea and 3 hours and 15 minutes for Trichoderma."

I'd still be interested to see a layman put it to use. I think im starting to get a trich problem so im gonna finish the flush and zap the myc under a couple uv b bulbs i have and see what happens.

I think a lot of people on here are a little too quick to jump out at these ideas as wrong or stupid. Always encourage experimentation. Mycology does end in a -logy, doesn't it?

I'll make a thread with pics if i end up doing it.

I can't see why those kinds of doses of UV would kill one kind of fungal mycelium (trich) but not another (good mycelium).

Search my posts for successful experiments I did using UV to kill bacterial contams on agar.

Well, fungi like trichoderma are much different in structure than say cubensis. There are thinner walls to their cells that, in my understanding limited thought it may be, make it easier for radiation to penetrate. There are also experiments done killing trichoderma with electrolysis though i don't think the methods are feasible for any hobbyist.

Agreed, the best bet for any experiment, for me or anyone else, would be to have the light in a closed location. Technically speaking UV-B rays rarely penetrate glass or any other material of the like. THAT DOES NOT MEAN PRECAUTIONS SHOULD NOT BE TAKEN. UV-B rays are the least detrimental to one's health but the real risk is your vision not your skin so much with these lights. Never expose yourself to the light while it is on.

But some people in this thread treat UV light like it's freakin gamma radiation. It's not good for you but it is all around you and sunscreen can protect against the amount and type of UV that the reptile lights i will be using emit.

Wish me luck, keep studying, and i'll let you know what i find

I use a Waterproof UV wand that sits submerged under water in my humidifier tank, it kicks on for an hour every 8. I just make sure not to look at it in with my eyes if filling my reservoir. This is for the slime and gunk that builds in the humidifier. My mushrooms are not subjected to the light directly, but the humidifier tank is white and the blue light deff shines up the whole tub, at night it looks like a moon in my tent (: I don’t think the light making it through the tub is anything but negligible, though the direct light has certainly left a mark in my vision for a few minutes after an accidental glance. I also notice a slight burn scent that he collected on the UV want itself. I never touch it. Be careful with UV peeps.
