1. Cook your rye grain in ro water in a big pot - boil it slowly until you see just a few kernels burst
2. Pour that into a collander and let it drain WELL - an hour or more.
3. Spoon some of this into your quart jars - fill your jars about half or just over half full - this is important. If you fill them too much the mycelium will run out of air before it is all colonized. No more than 5/8ths full
4. Let the jars sit for 12 hours before you do anything else - you are letting endospores germinate so you can kill them quickly.
5. Pressure cook them for an hour at 15 lbs.
6. When they cool, shake them up to get out any lumps.
7. Find a small room with no drafts - set up a table and a chair in that room
8. Arrange your jars so that you can easily get to them and move on production line style - it has to be easy, practice a few times so you get it down
9. Loosen the lids of all the jars but don't open them
10. Spray the room, the jars, the table with lysol and walk out of the room - everything should be set up on the table including yoru syringes
11. Take a shower, put on clean clothes
12. Go into the room, sit down and begin
13. Each time, you lift the lid just far enough to get your needle in and squirt about a cc into each jar - try to get the liquid down to the grain but don't worry if you don't, keep that lid open the least amount of time possible.
14. After you are finished, tighten all the lids and shake all the jars. - no clumps, no lumps - each grain must be individual.
15. Wait
16. When you see white bits growing on some of the grain, wait a day more and then shake the jars again - a light shake is all you need, you are trying to break up the mycelium and distributed it among all the kernels
17. When you see more white growing in more places - wait a day and do it again. The lid is still air tight and everything growing inside is using only the air in the jar - you have a limited amount of time so you want the mycelium distributed as much as possible.
18. When the grain is grown out - it may not be as white as you had hoped, don't worry but be sure that each kernel is covered - usually at this stage it looks more gray than white, open the lid and cover it with a plastic baggie. It has to be loose.
19. In a day or two you will see that everything is white - by the way if you EVER see anything but white, throw out the jar. This tec devolves rapidly if you are growing mold in your open jars.
20. Now mix coir and vermiculte 50/50 and water it up so that when you grab a fist full of it and squeeze, some water dripps out of your hand - DRIPS, not pours. No substitutions or you will have to adjust the ph.
21. Put this stuff in a turkey bag, twist it closed, put the turkey bag in your oven on warm at 160 degrees until the center has been at that temperature for 1 hour.
22. When it is cool, take the baggie off of the jar, spoon (clean spoon) about an inch to an inch an a quarter (after it has been compacted) onto the colonized grain and put the baggie back on.
23. Spray the inside of the jar (the dirt) once or twice a day, lightly.
That is all you have to do, you should get a quarter to half an ounce dry from each jar. You will get some border breaks, if you don't like that, wrap the jars with aluminum foil up to the casing. No light, no fruiting chambers, no fanning, no tubs, no birthing, no dunking, no injection ports, no glove box, no tyvek, no waiting and waiting and waiting for colonization.
There are a few caviots - as I said, if you see anything but pure white at any time - throw it out, jar and all and don't let it sit in the trash in your kitchen - I am serious, this method is naturaly resistant to contamination after the start, but once you start getting contams in the air in your house, you are done - all over, you don't get to do it this way in that house again.
Don't worry about temperature, if it gets cool, you just have to wait longer (no freezing though). But if it gets hot - anything over 80, the plug in the jar will start swimming in it's own juice. You can try pouring that liquid out but it will reduce your yield at best and will likely drown the mycelium and then get infected.
