a question about casings??
    #427211 - 10/16/01 12:07 PM (15 years, 4 months ago)

I'm about to begin my 4th attempt at casing. All 3 x's before this have failed to the green mold. I need to know do u have to sterile your bottom and top casing layers?? If so, what is the best way?? I will be using straight verm. layers......

Sterilize the verm by nuking it for several minutes in a plastic cup covered with seran wrap or better yet use a pressure cooker.

Right after you've made your three layers, cover with seran wrap held in place with a rubber band. That way, nothing falls on the casing and if you did a good job sterilizing the verm, you shouldn't have any problems. Just be sure to lysol the room, close the vents, and use rubbing alcohol on your hands when you make your casing

Hi,

Many contaminants attack casings because they're too wet. I make big batches of casing and sterilize one hour in the pressure unit, squeeze out excess moisture, then apply. Only lost one casing in two years.

Good luck!

Dito... Insomnia is right on... I follow this procedure pretty much like he put it and have never had a problem. I've found that the easiest way to make a batch of contam-free casing is to fill a bulk-spawn bag (mine come from Mycelium Fruits) with your casing of choice and PC at 15lbs. a good half hour. With this method i've never had a contamination problem... untill of course you've recased for about the 3rd time... but then things just tend to get a little messy.

I've never used the microwave for sterilization. I'm a fan of pressure sterilizers. Filling a quart jar or bigger with 50/50 wet peat moss/vermiculite, sterilized for an hour or so, will yield plenty of casing material. Of course, your mileage may vary.

plastic tupperware would probably melt... maybe something rubbermaid would work but i wouldn't exactly recommend it. i've read that you can PC your casing in the same bags that the vermiculite and perlite come in (schultz brand anywayz), but i've never actually tried it cause i just use the autoclavable bulk-spawn bags.

yes, hydrate the casing mixture before you PC... if too moist after PCing, squeeze out excess moisture with your hands (i'd use gloves).

awe chit... i think you're on to something there josh. those should work perfect, and there's no way in hell that PCing gets over 400 degrees.

5lbs. pressure - 228 degrees F
10lbs. pressure - 240 degrees F
15lbs. pressure - 250 degrees F (ideal/30min.)

I use those reynolds oven bags religiously and they work great, I recommend them highly. Just be careful about letting the bag touch the sides of the pc'er, as they might tend to stick. Usually about 45 minutes is plenty.

Sweet!! I've got something that will work then........now, if i'm gonna case 6 of my 12 jars, how many cups of verm. should i sterilize for the casings??

Also, if i just sterilize a bunch and have some left over....would i have to re-sterilize the next time i go to use it?? or will it be okay not to?? as long as i keep it in the reynolds oven bag and make sure it stays sealed?

just use good judgement on deciding how much casing to prepare... you should have at least twice as much casing prepared as you do substrate (it's kinda like a sandwhich - bread on top and bottom, etc.)

as long as the bags stay sealed you shouldn't have a problem, but then again safe is better than sorry. (i always re-PC before using... no matter what).

No, just clean use a clean casing tray. Might I suggest using perlite as a bottom layer?
