Contamination Probabilities
    #5169989 -

Ok. If i inoculate the jars in a glove box, use tyvek on the jars, pressure cook my susbstrate jars correctly, and pressure cook the casing, what are my chances of getting contams? More importantly, im going to be using two cool mist humidifiers to supply FAE so that leaves it open to bacteria from not using a hepa. Does this risk my shrooms getting contaminated in the terrarium? If so, how can i filter my cool mist? Can i insert both of them into a rubbermaid with a hepa filter? yadayadayada, thanks for the help in advanced.

you have a high probability of success, thats about it.

If you were expecting a number use this formula to get your answer:  210*2/0 :wink:

About 50/50  :grin:

The cool mists usually come with little filters. Either way, the FAE they provide is great for keeping contams away. I put about 1/4 cup of hydrogen peroxide in with each gallon... no hepa and no contams after running for over three months.

^^Yep, the FAE provided by the coolmist's will keep contam's at bay, as they only come onto the scene when there is stagnant air. As mentioned also, they have good little filters on them!

Awesome! Thank you so much guys. I was already contemplating of ideas on creating a filter system. No need on waisting the extra money now! Woot!

Any suggestions on ways to cover the air escape gap in order to use the whole method? Should i stuff it ith something, use AC tape, etc?

There is no reason to even attempt to keep the fruiting chamber sterile. Filters are not required. As said above, air exchange is the key to avoiding contaminants.

Bacteria is the contaminant to watch for during colonization of your jars. Proper sterilization and cleanroom procedures will eliminate it from the brf. Once colonized, the myceium can fight bacteria off on its own.

Molds, such as trichoderma and cobweb are the contaminants to watch for in the fruiting chamber. Proper air exchange will prevent these. Pasteurize your casing mix, don't sterilize it. A sterilized casing will be more prone to contamination than a pasteurized one.

oh, BTW:

>>>>im going to be using two cool mist humidifiers

unless you're doing a martha or something big, you only need 1. I'm running two 30 something gallon tubs with one cool mist, and I could probably hook another tub up.

Yeah but i have two levels on my terrarium now, i need one cool mist for each level. Im going to be using my hygrometer to experiment with it tomorrow to test if an automatic timer will be necessary and if so how long they should be on.

Thanks Roger. Now they told me that the two Cool Mist will allow plenty of fresh FAE in my terrarium. I was thinking though, do i need some sort of vent to let old air out of terrarium? I am making my terrarium almost air tight, and the two cool mist will be throwing air in but their will be no way for air to go out. Does this matter? I was also thinking of adding one small fan to each level to keeo constant air flow. Is this good idea?

Another qestion. What is the difference between pasteuriing and steralizing? I thought they were the same thing.... :frown:

So long as it's not truly air tight... the air will find a way out. But, if your exaust is constricted enough, you'll create a high pressure area, reduce the ammount of inflow, and put a strain on the ole cool mist. This can also cause your cool mist to leak water from it's seams. I'd drill an exhaust hole or two the size of the inflow. No need for a fan.

What is the difference between pasteuriing and steralizing?

Get one of these, I have had far less contamns sence I got one...... 

no one can tell you odds on your stuff contaminating there are too many factors. Just use steril techniques, follow the techs on here, and you will do ok. Although I think kitties help lucky or something :wink:
