HEPA Filter to cut down on contaminations in spawn room?
    #15753562 - 02/02/12 08:44 PM (12 years, 11 months ago)

I had a couple of tubs go bad last run and I want to cut my chances down even further of having a contamination. I want to buy a portable HEPA large Room filtration device and let it sit in my spawn room for a few hours before I spawn. And I also want to filter the air in a my fruiting rom. This might be a silly question but is this really very effective in practice, theoretically it sounds great but I'm wondering if it really works as well as one would expect. Please and thanks!!

It would definitely reduce the amount of unwanted spores & bacteria in the air that could land on your substrate, and probably make you feel better by having cleaner air :smile: especially if it's a true HEPA. That's what it's built for isn't it?



Of coarse, but it seems like its too easy.  The practical application of some things turns out to be far from what was described theoretically, IDK like i said it just sounds to easy.  And if its so effective why have I never seen it recommended before, seems like that would be the answer to every contaminated substrate question i.e. go buy a HEPA large room air purifier and be done with it! Do you have any experience with HEPA devices and mycology?

I don't know man. seems like sitting in there whilst the room is undisturbed might not do much if you consider that you stir up most of the contaminates off the floor when you walk around. :shrug:

I've seen it recommended countless times here, and if you live in a humid, smoky, dusty trailer, (like I do) then IMO it's a no-brainer that it would help tremendously. And I have very little experience in mycology, just a crippling amount of research, but as a self-diagnosed germaphobe I do know about doing everything in your grasp to keep things clean. So far have had 0 contams (knock on wood) in my first 5 cakes, but they're still around 80% colonized, and one prepared without spores in it to test my sterile procedures. If you can get a deal on one, or have the cash for a new one, why risk it? It's not like it could harm things in any way, only help or do nothing at all.




I appreciate your take an input but unless you have experience with it its only speculation, I had already concluded that in no shape or form a could it hurt. The problem is a good unit is expensive, or if you build one your talking about a substantial amount of work. So time and money are 2 things I don't have at the moment, I'm poor working college student but if it really is effective I would go buy a good unit or maybe build one, it just seems like a lot of effort or money for something that  "It's not like it could harm things in any way, only help or do nothing at all" so IDK I was hoping I could find somebody who had contamination problems, bought or made a HEPA filtration device, and implemented it back into there mycological work and what results they noticed.

How much it will help depends on the true cause of your contamination. If your tubs are contaminating due to an excessive amount of ambient mold spores then it would probably help quite a bit.

Letting the air settle is more important in my unprofessional opinion.

I say this because the mold spores are stuck to you, your clothing and the walls. I think a flow hood will do little for you besides stir up the air. They provide a sterile environment, and it won't sterilize a whole room/house, protect you from a bad tek, bad sterile technique, bad grains, etc.

Most of the spores that are hanging out in the air will land after a couple days of not going in the room (and stirring up the air). When you do go in there, you can air-bomb with some bleach/water or ClO2/water (Pool cleaner, aquarium cleaner, hiking water purifier). Wipe down the surfaces too. Don't vacuum before doing this. Give bleach 10-20 minutes to settle and work it's magic.

In the meantime, perfect your spawning technique. Coir isn't a good substrate for germinating spores, and a properly pasteurized sub will not contam even if you give it a couple weeks. I always use oysters for my test runs, because they are so easy. Cloning is very simple, if they sell them at your grocery store. Make a few control groups too. Don't inoculate one jar. Expose one jar like you're inoculating it, but don't actually inoculate it. Fruit a tray of cased grains. Don't spawn to a tray of your pasteurized substrate. You'll need to learn to trouble-shoot and test stuff anyways, if you're serious about mycology.

QFT! I have coir done with "elementary coir tek" that I pasteurized probably 3-4 months ago, and its still nice and clean. actually going to use it today.
