These have become my new most hated threads

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

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.

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.

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.
