How to do a Casing:
1.)Clean container with alcohol(71% Isopropyl)
2.)Shake grain jars to break up mycelia(makes it easier to get the grains out)
3.)Pour grains into container(get grains as level as possible)
4.)Cover grains with 1/4"inch of Coco-Coir(prepared by wetting to field capacity then PC'ing for 20 minutes at 15psi)for every 1"inch of substrate you use=example-->Your substrate depth is 4 1/2" inches deep, then add 1 1/16"inches of Coir. #"inches of substrate-add 3/4"inches of Coir.
5.)Get the coir as level as possible[do not compact it]
6.)Cover coir with plastic wrap(Saran or Glad Wrap)and cover entire container top with foil(poke a couple of small holes for gas exchange)
7.)Place container somewhere so it will stay at or around room temp(70*F-80*F)and keep in the dark
8.)After 3 days take a peek and see if you have white mycelia poking up through the casing layer and if you do, at this point you can patch those areas so your casing layer gets colonised all at the same time. Meaning that your mycelia appears to be coming up everywhere across the casing layer at the same time.
9.)Once you see over 75% of the mycelia has surfaced(almost surfaced, you want it to just be visible under the surface of the coir), remove the foil and plastic wrap and give it a good misting and fanning.
10.)Place into your fruiting chamber(which can be just a larger container with about 2"inches of perlite[wet] across the bottom)
Fan and mist daily!
Hope that was helpfull
