No no no, please no. Stop with the UV lights. Everything that needs to be sterile goes through the PC. UV light damages skin, retinas, almost all plastic and rubber. In addition, it will not work anywhere there is a shadow, so any stuff in your closet or dirt or really anything that will block the light renders this whole thing useless. You are drastically raising your risk level for absolutely no benefit.
Also stop dousing yourself with iso. Not necessary.
Lab equipment companies still sell UV in their hoods as a way to make money. Most labs I worked in stopped using UV years ago because of the dangers of UV coupled with the ineffectiveness in actual use conditions.

I buy this light to sterilize my n95 masks. It is very important that this light do sterilize. If my mask is not properly clean and I believe it is clean,then I will end up cross contamination. I test it by putting a thin polyester smelly sock inside a small box to sterilize for 5 minutes. The sock came out smelly. So I want to return it. But after fellow amazon customers reply to my concerns, I decide to keep it. Seller also sees my questions and provides documents to proof that this is a real uvc light and at the same time to solve my questions on why my smelly sock comes out smelly after sterilization. After answering all the questions seller asks, seller tells me to use it for 15 minutes and the smelly sock came out clean. Proof provides by the seller is not as persuasive as my own test which gives me a peace of mind.
I sterilize my n95 mask, car keys, letters, shoes, jackets and backpacks. In the past, I have to leave everything I used outside in my garage, read my letters in my garage, spray my car keys with alcohol, air out my n95 mask for ten days in order to reuse. Putting on a jacket that might be contaminated is really scary too. Oh. I just hate all these worries.
Now, after testing out myself that this light do sterilize. I sterilize everything I use from the outside. Thousands thanks to my fellow amazon customers who help me out and to the seller who has a lot of patience for answering all the questions. Having a light that really do the job is very important. Thanks to everyone
I put the light on the carton box to sterilize my masks but I don’t want my jacket to explose to uv because too much uv will lighten the fabric. I separated the jacket and the masks by using the carton.

I never claimed UV can replace sterilization, but it helps create a cleaner work environment.
Yes you are correct. Sterilization and disinfection are different. They are not interchangeable. My response was not directed at your comment except for the last regarding UV in hoods.
UV does not work for our purposes and poses a very real risk that many discount. Just because it looks cool in a lab catalog does not mean we should be putting these things in our closet.

I install it where the blueprints tell me. I’m not an architectural engineer by no means. I appreciate the attack on my trade as well. That is why I am here asking the question. I have installed it based on plans that have been approved by the government and hospital boards. To kill mold spores that pass through filters, and thought it would be a beneficial idea to my home setup. A simple yes it works or I haven’t seen any results would have been fine HelloImBob. “Please please stay away from it if you have to ask about it instead of understanding how it works and the dangers associated with it” if that is your philosophy on life, then maybe you shouldn’t go to advanced or auto zone and ask for help with replacing spark plugs. If you don’t understand it, just shut up and do what you know? How about you don’t discourage expansion of knowledge and learning new things. I’ll take your advice and next time I have to go to a house with a owner that has your type of attitude, I’ll say, “I can’t do it, I don’t understand and shouldn’t ask questions!” Literally, telling me to not educate myself and ask questions was pretty shitty.

These have become my new most hated threads 
Quote:
Stipe-n Cap said: UV-C lamps are not permitted on cabinets at the NIH because the risk outweighs the benefit, If it's not good enough for them, it's not good enough for you.
UV-C provides a false sense of security, much like using antibacterial agar but without gruesome DNA mutations. UV-C has very few, if any uses for home cultivation purposes, unless you're attempting some advanced mutagenesis type shenanigans.
UV-C absolutely does not outperform isopropyl for sanitizing your work surfaces, ISO conveniently comes with zero risk. You cannot sanitize the atmosphere, so stop trying.
UV-C is subject to the inverse-square law, cannot penetrate glass, plastic, or liquids which makes UV quite pointless for mush cult. Even if UV-C were 100% effective, the moment the light is switched off in a normal open air environment, any benefit gained on the swings is lost on the roundabouts.
Quote:
Ultraviolet radiation is a form of non-ionizing radiation, and biological effects from it vary with wavelength, photon energy, and duration of exposure. The 100-280 nm wavelength band is designated as UV-C, which is used for germicidal purposes.
The sterilization/decontamination activity of UV lights is limited by a number of factors, including:
Penetration – In the dynamic air streams of BSCs, microorganisms beneath dust particles, plastics, and work surfaces are not affected by the UV light because it cannot penetrate particles so far from the UV source.
Relative humidity – The germicidal effects of UV light drop off precipitously when relative humidity is above 70%.
Temperature and air movement – The optimum temperature for the UV lamp to be effective is 77-80 degrees F. Temperatures below this range result in reduced efficacy, and air movement can exacerbate this.
Cleanliness – Dust and dirt block the germicidal effectiveness of the UV lamp, so weekly cleanings are necessary.
Age – Check UV lamps every six months to assure proper function, as the amount of germicidal wavelength emitted decreases with bulb age and hours of use.
Overuse – UV lights are routinely left on overnight or longer in an effort to decontaminate workspaces, but this practice can result in the germicidal wavelength no longer being produced by the bulb.
For these reasons and other concerns, the National Sanitation Foundation (NSF) does not recommend the use of UV lights
https://www.ehs.washington.edu/about/latest-news/trouble-uv-light-your-biosafety-cabinet
The National Sanitation Foundation discourages the use of UV-C. UV-C has no place in your home cult lab. UV-C is absolutely 100% pointless and represents an unnecessary health risk. Straight up noobs arguing in favor of x technique or technology without the appropriate foundational knowledge/wisdom appears to be becoming the hallmark of psychoactive fungi cultivation.
Take pride in your work, do the appropriate research, and listen to those here who have been around for a while; You might be surprised to discover that they actually know a thing or two.
If you have questions regarding equipment function and efficacy, read this:

Sanitizing with soap, iso, or some other agent, is far more efficient/practical than UV. Noobs are constantly trying to reinvent the wheel by complicating things.
Still air? Too simple, what about a shmuvbox 🤔
Sanitation? Why use boring old sanitizing agents when we can harness the power of the electromagnetic spectrum🤔
Monotub? You mean automated air exchangers controlled by PID, hygrometer, and co2 sensors🤔
But, what if I used all of these 🤔 I bet I'm the first to consider the massive implications for exponential gainz.

Or perhaps My fingers just have frostbite from hanging out too long at the summet of mount stupid.

The answer:
Don't use UV in place of sanitizing agents like 70% isopropyl.
Quote:
For these reasons and other concerns, the National Sanitation Foundation (NSF) does not recommend the use of UV lights in BSCs.
The National Sanitation Foundation doesn't even recommend it, so just don't. Check out what boring old soap can do:
Isopropyl is widely used, the fumes are irrelevant, but do whatever you guy's want, I'm not even your real dad anyways.

UV is essentially a Noob Goldberg machine, like all of the other over-nooblicated contraptions listed above. Does UV sanitize shit? Let me answer with a question: Do humidifiers add humidity to monotubs?
Sure, breh. Do whatever makes Y'all happy. I only post to add balance to otherwise ridiculous threads overrun by the unjustifiably overconfident, you know, for posterity and the folks who've figured out the search function.
Am I salty, yes, but what's life without a healthy pinch of salt? Anywho, did you know that labs running UV used to report folks with sick tans? true story. Worse case scenario you'll end up looking like a bronze myco-stud.

You jest, but things like that were considered. O3's heavier than O2 tho, the ozone layer is suspended betwixt the upward convection of the troposphere and the downward weight of the stratosphere. No good way to generate or to transport generated ozone up there, more practical to find alternatives to ozone depleting substances.

I think that it would be best that a person practice their sterile technique instead of relying on either chemicals or uv lights to produce clean work. this shit ain't rocket science.

Lol says the blind guy with DNA damage who likes to play with uv-c
Way to dodge the question if you have experience with them.
If you had experience you would know they destroy plastic and just about everything else.

UVC is dangerous. That's the freaking point. UVC demonstrably kills certain pathogens interesting to us, notably trichoderma spores. That's also the freaking point. I can still see, I don't have three eyes, my tubs have not degraded into dust.

It's ok to be scared of UV bob, don't use it.
Other adults may choose to learn the dangers of UV and how to use it safely.
It doesn't change your life. At the same time, there is no reason to shoot down the discussion.

First of all i wanna say that i´m absolutely with you.
But discussions like that lead into nothingness. I formerly had to learn it the hard way in a thread, when a guy (a vendor) advised to add peroxide to their misting bottle regularly. The rage began, finally our big admin needed to jump in, and even strengthened this guys back quite a bit. For a moment i thought about setting up a password i wouldn´t remember, and better leave this place.
But stories like that will always happen. It´s human. I don´t care anymore.
Let´s be proud we´re able to produce great yields without UV or H2O2, that´s real cultivation.
Folks, just make clean spawn and start work.
Otherwise just do what y`all want, as said i don´t care, just wanted to place my statement.

Bob, spare us the straw man arguments. You might inquire as to how people are using the UVC light, before telling us that we're all going to die.
Nobody is arguing that UVC penetrates and kills stuff below a surface. Nobody is recommending having them on when you are in the room. Nobody is recommending leaving them on all the time.
I use them to knock back trich spores in the air and on surfaces. I run them in my room for 30 min just before I do bulk spawn operations, in conjunction with other standard sanitization measures. I'll run them after I do a periodic room clean, after vacuuming, as the dust settles in the room. I turn them on and off from outside the room, behind a closed door. Used this way, there is no risk to the grower. Whether there is benefit is up for discussion, but it's straightforward to use them safely. They are proven to kill mold spores and bacteria on surfaces and in air.
Since I have added them to my routine, I have seen my trich infestations plummet. I have seen no degradation of tubs or other materials in the room. Cultures in petri dishes and tubs are unaffected, as any amount of plastic blocks UV light quite well.
Your stridency and refusal to engage in productive inquiry just makes me plan to skip by your posts. If you want to be listened to, you're going to have to mature your style, my friend.

Anyone use UV-C for sterilization?

Probably posted before, looked around. I found a UV-C light on major online retailer (A-Z). Aparently these C wave black lights will kill fungal spores, viruses, bacteria. It interrupts DNA. As a HVAC tech. We sometimes install these lights in large units at hospitals in the air supply, but I ways thought it was a placebo to upcharge contractors. Since it’s $17 with a 4.7⭐️ at 1160 reviews, I feel like it worth turning on and leaving for 10 minutes in my work area. Some guy in the reviews said he tested it on his N95 masks and it works.
Anyone try this, or have honest feedback?

You are asking a question about uv light , that you basically answered lol .
UV exposer can do damage do not work under it.
Cleaning you area isn't going to stop the bacteria in the air when you move....
LOTS of people us uv to sterilize but you can do that with many other methods too... I've used uv to sterilize other things but not my SaB , it's not really a "sterile" air box and keeping it that way would be meh. It depends on what area/ what you are doing ?

I wouldn’t work under it. Like it claims, interrupts dna. My work area and grow area are in my walk in closet. I thought about mounting it to wall above my SAB. Turning on and walking away for 10 minutes. Then spraying down myself with alcohol like usual and turning off before I go in. At least killing a significant amount of spores prior to me walking in. I know it works. What I’m asking is: are home UV-C tube lights powerful enough to do this? $17? Before I stumbled on this I assumed a UV light powerful enough to sterilize an area is something you’d have to buy commercially. Just wondering if others have had success with this

Some modern lab equipment will come with these installed to sanitize the work surface. The usage protocol is to turn the light on for 15 minutes before and after work but not to work with it on. UV light can be damaging to your eyes as well as your DNA.
