Myco Bag Step by Step (Substrate)
A supplement to https://mycotopia.ne...t-a-4-part-tek/
Things you will need
Myco Bags size 8x5x19" .5 – 5. Micron, will work best..
Tyvec mailing sleeves (optional but highly recommended)
PC (for sterilizing, optional pasteurizing)
Impulse sealer (optional but highly recommended)
Your favorite substrate
I will be using coir/coffee found here https://mycotopia.ne...t-a-4-part-tek/
I will be sterilizing this sub because of the coffee, if you plan on pasteurizing skip the PC steps and place you bags on a sheet pan in a pre-heated 160-170* oven for 3 hours, careful not to touch top or sides.
Mix your substrate
Evenly distribute the substrate between the bags, I will be using 4 bags for 2 gallons of sub
Fold the tops over, or squish down (do NOT roll them up) so when PC’n they don’t expand and possibly burst
The best way I have found to PC the bags is to put each one in a Tyvek envelope/sleeve from the Post office. If unable to use Tyvek you will need to use a small towel or equivalent on the sides of the PC, so the plastic doesn’t touch the metal. Then raise them off the bottom out of the water.
I am able to get 4 bags in my PC comfortably . PC @15 psi for 90 mins
Once cooled, remove the tyvec sleeves and save for next time. Now is a time for cleanliness, I do this out in the open but try and be somewhat quick n careful. Get your spawn jars ready to break up and dump in the bags, I will be using 1 quart of spawn per bag, this will make the approximately 1:2 ratio. Open up a bag and dump the jar of spawn in and quickly close the bag.
This is where I like to seal with an impulse sealer, or vacuum sealer without using vacuum. If sealer is unavailable you can use clips, or fold over several times and tape
Once sealed, use your hands to break up the spawn and mix well into substrate.
Set bags in a warm place, they will colonize within 7-10 normally, I will wait till I see pins in the bag, then I open the bag and set them in a DubTub FC. Some people like to grow invitro, in that case just let them grow till ready to harvest then open the bag.
