And how many people here are going to use it properly compared to not?

It's like playing with fire, there is a higher chance something bad is going to happen than it being helpful.

Plus what is properly in this hobby?

It has it's uses but it's better for fish tanks and post filter HVAC.

It scares me to think somebody who doesn't know what they are doing tries using it only to ruin their eyesight or something.

When something is contaminated get rid of it or do agar transfers or whatever.

Change what facts that it's simpler to grow mushrooms without using uv-c?

That it's more useful in HVAC or a fish tank?

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 πŸ€”

Sanitation? Why use boring old sanitizing agents when we can harness the power of the electromagnetic spectrumπŸ€”

Monotub? You mean automated air exchangers  controlled by PID, hygrometer, and co2 sensorsπŸ€”

But, what if I used all of these πŸ€” 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.

It's useless unless you have a special quartz glass, useless if it's not transparent, useless useless useless for 99% of the people that's might attempt to use it and just end up hurting themselves in the process

Sure there might be some use for it but should people that don't know any better play around with something that has a way higher chance of being dangerous than it does useful?

If you cared about your fellow man you wouldn't defend a topic that could so easily cause them harm without them knowing any better.

They can be dangerous and there is no point to them in this hobby unless your smart enough to figure out that reason on your own.

I'm all ears if you come up with a tek on how to use it correctly

It's not like we're trying to keep a secret hidden from everybody.

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.

I agree with parts of this statement, but when you shut the light off the entire surface doesn't immediately become as contaminated as when you started (necessarily). Contaminants will fall randomly onto the surface over time. So the benefit is not all lost immediately, it is lost gradually over time (with regards to the surface sanitization). The light doesn't have to be used in an open air environment as you described though.

Iso is flammable and must be purchased regularly, so there are risks and greater requirements for resupply. In an ideal world you should use both for maximum sanitization.

Also just to be a further contrarian, you can technically sanitize and even sterilize the atmosphere in small spaces like labs, this is how labs are decontaminated in cases of serious biological release. It can be done with formaldehyde gas, but before you even say it, of course it has no place in this line of work.


I agree with everything below.
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

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.

Right on. I've only used UV-C tubes for EPROMs. Definitely underestimated it, burned myself pretty good first time I erased a bunch.
How do you employ your UV-C tube for cult work?

It seems a few here are suggesting we shouldn't discuss something because it could be dangerous when not used in a safe and informed way?

That's a very enlightened perspective. I wonder if that concept has ever failed culturally in the past? :mushroom2:

You sound brilliant.

When you figure out a way to use it, let us know.

Until then I'll only use it for HVAC and fish tanks, EEPROMS ect.

How are you going to sterilize something that grows beneath the surface?

Use agar for cleaning up a culture.

People here waste time and energy trying to do things that will fail instead of doing them the ways that work and have been described in full detail with pictures.

It doesn't get much easier than starting clean grain spawn over and over until you run out of room instead of trying to fix a problem that isn't broken.

Throw out your contams and start over unless your trying to save a rare ass clone or something and in which case you probably aren't in this situation.

There are many possible solutions.

You could purchase a grow tent (6 ft x 4 ft 6ft) for your work and place the uv lamp above your work surface (small desk in tent). You can iso the surface before, shut the tent and turn on the light with the tent closed for 10 minutes and then shut the light off (all from the outside of the tent using the UV lamp cable).

Then go in and iso the surface again if you want (or don't I don't care what anyone does here).

Or you could mount one in a SAB (with an external power cable), UV doesn't really pass through plastic as some naysayers have already pointed out.

Instead of being sure something can't work people should open their minds a bit and think of ways it could.

I want to be clear, I think most of the work people do here can be done in open air, but if we are talking optimal setups there is no need to be close-minded.
