Casing Tonight
    #2080922 - 11/07/03 02:14 PM (13 years, 10 months ago)

Tonight I'll be doing my first casing ever. I've got three PF style cakes that are almost done being dunked and cold shocked. Any last minute advice or things to watch out for?

And I wouldn't have gotten this far without the forums, so thanks to everyone who's helped me out.

what casing material are you going to use?
how are you sterilizing that material?
what sort of pan are you using?

I'm using straight vermiculite for the casing layer. I'm not quite sure as to how I'm going to sterilize it, I was thinking adding the right amount of moisture to it then sterilizing it in the microwave. I'm casing in a regular foil cake pan.

I like sterilizing moist verm and casing material in quart jars with my pressure cooker. I like it because I feel it's easier to adjust the moisture level, seal the stuff in a quart jar and pressure cook it. Water doesn't evaporate like it would in an oven or microwave.

Go with a bottom layer of moist verm in your casing. Half inch is enough. If the verm is sterile, it won't contaminate so easily.

Last thing, try to get at least 2 inches of substrate in your pan (use a smaller one if you must). It's not that important but it's all about getting good sized shroom instead of many skinny ones. At least, that's what I noticed the two times I cased some cakes.

good luck.

Is microwave sterilization still ok? I don't have a pressure cooker.

Sure -- why not? Sterilizing the casing isn't required, but a lot of people like to just to be safe.

Make sure you squeeze out all the extra water (so only 1 or 2 drops come out when you squeeze your hardest -- this is the right moisture level) and try to apply it very evenly (the substrate, too.)

Well it's done.

Thin bottom layer of damp vermiculite, three one pint PF style jars crumbled up evenly and a thin layer of damp vermiculite on top. Thanks again to everyone...hopefully everything turns out as good as I'm hoping.

I'm curious about your decision to cold shock the cakes prior to casing. You want the temp high when the broken up cakes colonize the casing. You cold shock when you are ready to fruit. Why cold shock during the cake stage when you plan to case them? I'm just curious?

i hadn't realized you didn't need to sterilize the casing. i've never cased before but i plan on trying it as with the jars i will be starting soon. i'll sterilize it though just to be safe. i want every thing to go right. can you get away without sterilizing it no matter what you are casing with( verm, coir, pete moss, ect.)

i was also going to say something about you cold shocking them before casing. i've always thought that should be done after the mycelium starts growing again and establishes itself to initiate pinning.

You should sterilize any casing matter. The casing matter consists of a moisture holding substance and will proceed to feed water to anything which might be present and want to grow in your fruiting chamber. If bad spores of anykind are present and you don't sterilize they will grow in the high humidity environment you provide. Even after sterilization many loose casings because mold or anyother spore in the air lands in the casing and makes use of the high humidified environment. I've boiled coco coir for an hour and watching a seedling of some nature from the coir germinate and get two inches high by the time I next checked the casing. L8rs.

This is my first grow. I got the impression that when dunking you left the cakes in the refrigerator. So you're only supposed to cold shock when you're trying to induce pinning?

The "cold shock" is used to simulate a lowering of temperature which would happen in nature when it rains and is cloudy or when a seasonal change occurs, all of which initiates the growth of mushrooms in the wild. The higher temps are used to speed up growth, during the mycelium colonization stages. "Primordia formation: RH 95-100% Air Temp 74-78 Cropping: RH 85-92% Air Temp74-78"(Stamets). The lower humidity in the cropping stage, or growing stage, is due to need for more fanning for the larger cubies use up more O2 and need to be fanned more often.

Also, will this have any adverse effects on my casing? Or will it just take longer for the mycelium to colonize the casing?

It won't hurt them at all. I wouldn't worry. For they are now submerged under the casing, the mycelium that is. It shouldn't pin withing the cake. Light introduction, lowered temps, and air flow, all play an important role in the pinning stage. I'm not yelling at you or critizing your methods, just questioning them. I was curious thats all. L8rs.

Please, question away. Any help or suggestions from anyone would be greatly appreciated. I'm doing a grow log as well, just to keep track as this is my first grow.

I also had three more one pint cakes in the fridge, I took them out and I'm going to leave them at room temperature overnight while they are dunked. I'll be casing those tomorrow. Thanks for all the advice, and if anyone has any more suggestions, please let me know.
