Germicidal UV Light Sterilization.
    #7977633 -

I should post a tek involving this process,
but lately I have had an incredible success exposing all of my working spaces and materials to germicidal UV light minutes before inoculation. Although alcohol is been used in conjunction, I simply have to believe in the UV light, as I live in a co-op of 8 people, who achieved in an informal consensus, that cleaning is absurd, as things are always going to again get dirty. I remember a petulant childhood argument that I might have pledged in my golden years of age 9 to my parents.
Anyhow, I mean only to say, that in the dining room, ajacent to our kitchen, which is filled to the roof with dirty dishes, is where I do most of my work.
I was wondering if anyone has experimented with UV light in the past, or has any resources to read about it. I scowered the forums and found very little.

I never expose substrate to it, colonized or uncolonized, spores or LC, as I know that if bacteria fry underneath it, so should other microscopic life.. like skin cells.

I'm going down there now to experiment with the UV sterilized environment, at the pinnacle test and proving place, 12 G2G transfers.
Wish me luck!

I wish I could afford one, they would be great for cleaning the GB

mine was actually exhumed from an old fish tank, it was used to sterilize the fresh water. I used it for a little while to purify waste-veggie for my truck, but realize now it can be used for much more fun applications.
Check Ebay, i think two 5w bulbs are only 15 dollars or something, just search germicidal uv.
I would eventually like to mount one inside a small HEPA filter, somewhere, possibly at the air intake.

I do whole heartedly believe that would be sweet.

I doubt you'd think it was sweet when you came down with skin cancer. UV has no place in mycology. Not only that, it's totally unnecessary. Simple sterile procedure is proved perfect, and by following it you'll get 99% or better success without exposing yourself to danger.

Using a germicidal lamp isn't bad for you if you install the switch outside of the area to be sterilzed. Place your box inside a closet or other small chambered area outside of which you can put the switch for the lamp. This allows you to use a lamp without ever exposing yourself to the harmful radiation.

Having this, RR is absolutely correct about it being overkill. And, without a professional lab, I don't recommend the lamp either. Improper use of these lamps can cause severe burns in a matter of seconds (if certain strength levels are achieved) and will most certainly cause cancer as a result of any long-term exposure.

If you're going to have it, make sure you can prevent exposure of your own skin and entry of unwanted guests to the area. Use an external switch and have a lock to the area it's going to be placed.

What a dork, like anybody is dumb enough to let the UV hit their skin.

Roger, why do you think everyone is dumb?

I have used the lamp in several applications, always using excessive precautionary measures.
I have used it to sterilize my grow room before making casings, my fruiting closet in between casings, always in my glove box before G2G or other inoculation.
Always with %99.99 UV protective glasses ($4 from a welding supply store,) and always either having the GB superiorly covered, or simply, being totally absent from the area.

The point with this post was simply to find out if anyone else uses them, what kind, what for, and their process.

...and I suppose aquiring knowlege from the elders.
Thanks RR, your right about the neccessity, but like I said, I live in an almost 100 year old house, with sometimes more that a dozen people, with a consistent animal population of one dog, 3 cats, and 2 bunnies, as well as those who come with their companions.
Excessive sterility in my case need mostly be unnecessary, as the excessively soiled air in my environment calls for it.

and I don't think that the people on here are stupid, so much as I believe them to be lacking a passion for deeper, appreciative understanding, and greater adventurous creative escape into the future of both this community, and the entirety DIY mycology.

The same was though, some are compelled with their heart to write songs, and others, to take lessons to learn those of their forefathers.. some people want recipes, some people want adventures.

I was working for a contractor, last Summer, and noticed that all the new central AC/heating units had 2 large UV bulbs inside the home ductwork. It was completely shielded and all of the home air circulation goes through it at some point. I think this technology is popular in Japan as well. Perhaps those interested in reducing the wee beasties floating in the air might look to a retrofit kit (for their metal ductwork, not glovebox!) They are all over eBay.

uv-b causes skin cancer. uv-c is the sterilizing uv. it can cause redness of the skin if over-exposed, but has not caused any skin cancer in any known study. i was just berated for my use of a uv-c filter the other day on this thread by the way, i have the utmost respect for you RR, i was just researching this though and uv-c really doesn't cause skin cancer. hospitals have been using it for 60 years.

Quartz lamps seem to be very good at air and surface disinfection. It's more likely to skin cancer from longer UV-A or UV-B spectrum ar it penetrates deeper. UV-C is quickly absorbed by most materials including outer skin layer. Actually it is blocked by oxygen and you can smell ozone. Of course it is better to avoid looking directly into light or exposing open wounds.

I'll try combining chemical, thermal and germicidal radiation to achieve best sterility. It is important to clean air as mold spores are floating almost everywhere. Only thing I'm afraid of is that UV-C could kill also spores.
