rez effect?

Ok, so I've been looking for a new project and I wanna give the 'rez effect' a shot. Basically here is my plan that I have come up with from reading...
Bottom layer about 1/2in of coco coir bulk (that I have leftover from the monotub I made today...it's coir/verm/coffee) then cover with colonized WBS and field capacity verm at a 2:1 ratio. Then cover the top with a 1/2in layer of coco coir bulk. Will this work? Is this how the rez is supposed to be done?
Is it important that the verm be sterilized? I've read yes and no, but I guess I'll at least pasteurize to be safe. What do yall suggest?

Verm is sterile out of the bag, no contam problems here with a GT casing that is fruiting now. Verm was used straight out of the bag, moistened to field capacity with distilled water and am seeing good results.

nothing is sterile as is, unless youre getting medical equipment. you have a PC, use it. it take 30minutes, or you could just lose everything to cobweb.

I didn't just open the bag of vermiculite, it's been sitting around for at least three months since I took my first crack at the PF tek. Otherwise, I'd go straight out of the bag.
But I though verm did not harbor contams on its own for some reason. Guess I was wrong.

It doesn't harbor contams because it has no nutrients whatsoever. But if the bags been sitting in your place in the open for a while then ANY airborne contams will have found their way in, they just can't germinate on the verm. That doesn't mean that they won't once the verm is used on your cakes or trays. That said, if my trays are fully colonized I don't worry too much.

If your bag has been opened for a bit id definatly give it a bake in the oven to be sure. In the time its been open, lots of spores will have landed on it.
Some people actually have problems with contamination in the dry verm layer in pf tek grows because of this too, usually baking the verm can help since dry spores can survive steam and PC sterilisation temps.

Can I bake it dry at like 300F for 30 minutes and then add disilled water and be good?
Or should I wet it to field capacity and then put in jars and PC just to be safe?

i would not do the layers of coir and mix it all together. casing grain alone does not produce as much as using a mixture of grain and verm. grain dries rather quickly so by the time you are ready to fruit there is not enough water in the substrate to get optimal results(remember mushrooms are mostly water and that water must come from somewhere). while there is no nutrients in verm, it does a good job of holding water and that is the main reason it is often used for casing your substrate. mixing verm into your grain to be used as substrate provides water throughout. coir has some nutrients and holds water. mixing it in with your verm and grain will once colonized give you more substrate with the water the myc needs to fruit and nutrients to help feed it. since coir has nutrients it is quicker to contam and mixing it in rather than layering will colonize the coir faster witch reduces the time contams have to set in. more substrate with more nutrients and better water content = more shrooms.
good luck. -spock

Hoffman's vermiculite that was used in current GT rez grow says "It is completely sterilized" word for word on the back of the bag.

I think ya missed what I was saying spock, the verm will be mixed with grains. The top layer of bulk is just to keep all my grains covered and prevent the loss of moisture.
I've mixed plenty of coir with wbs, haha. I just wanna try the rez tek to get fruits quicker so I can trip at christmas, and I like trying new teks.

Ok, I'm gonna PC the verm in 2 quart jars for 45 minutes at 15PSI.
Is it a problem that the coco coir bulk that will make up the top and the bottom is two days old? It's in a closed bucket with a micropore hole. I only opened it to make that monotub two days ago.

So anyone got any input about if the old coir bulk is still okay to use? I just don't wanna mess up my rez effect experiment by using old coir. But it's the last coir I have and I don't really wanna go buy more...

I would say ok... but your contamination rate gets higher as you let it set... it has around 12 to 14 days (normally) to colonize ... knock it up quick!!!

Yeah, I guess that's what it's supposed to be. But I figured that a layer of bulk on top and on the bottom would do the same thing, more or less.
I figure a half inch of bulk will colonize easily within 5 days. So, that means I'm okay using that old bulk?
Also, I've read its a 2:1 ratio of spawn to verm. Is that wrong?
