Myco Bag Step by Step (Substrate)

A supplement to https://mycotopia.ne...t-a-4-part-tek/

 

Things you will need

Substrate

Myco Bags size 8x5x19" .5 – 5. Micron, will work best..

Tyvec mailing sleeves (optional but highly recommended)

Spawn

PC (for sterilizing, optional pasteurizing)

Impulse sealer (optional but highly recommended)

 

Substrate

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.

 

 

Getting started

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.

Wonderful.  Another clue to knowledge.

Well done Wharf! I like it you make it look so easy... What is your typical yield per bag?

[Ovoideocystidiata]

nice meaty fruits

[meyer]

So you are just cutting the bag at the top so you get all your fruits on the top. Seems to me that it might be better left in the bag, when you put it in the tub there is a lot of open air and it seems like if you took them out of the bags and cased all around with substrate you might successfully run an island method type of grow, and at least keep the grow hydrated better. If you don't want to use substrate, what about surrounding with moist perlite? Has anyone ever tried what I'm describing? Amy thoughts on which way would be better to it?

How many grows do you avg at any one time?

Like I said above nice job!

[Ovoideocystidiata]

once fully colonized they are somewhat like large cakes in a way, just in a bag.

Avg. 80g dry but have had well over 100g for 3 flushes.. just depends on the strain and other factors

i try and get nice spore prints, so i cut the top so they have room to spread out.. after the first flush i remove the bag completely, it will grow mostly from the sides on the second flush, the third flush seems to grow back out the top.. you can try for more flushes but is greatly reduced after 3. and yes you can throw perlite in there also, i found no difference between using perlite or not, i mist and fan one a day.

Awesome write up, wharfrat! I love a good pictorial.

[MLBjammer]

Yes, that is a keeper. Great work as always, man.

[Needles]

Awesome way to sterilize your subs Wharfrat. I like the way you use the mailer as a wrap the bags. I have been using tinfoil and its only good a few times before it rips. The vacuum packer is also a interesting method to seal your bags. Very cool write up and I love that full colonized jar of grain spawn......

ahhh, foil! good tip, i didn't even think about that. thanks

[FrmSpore2Siid]

Very Nice Boomers. Looks like an isolate. You did most of the hard work already. Hopefully its aggressive. Love the tyvek bag idea.

[Juthro]

I love watching you work Wharf.

Always impressive my friend.

:)

[happy4nic8r]

I tried a large cat food bag, don't know what they are made of, but they handle heat very well, don't melt or burn, and I use my grill to pasteurize, it keeps a perfect temp with one burner on low.

 

Same mico-bags inside. They don't seem to work as well for me as they do for you, but I'm doing it at 45 - 50 deg, so I expect it to be almost long term storage.

[SparkyAnn]

Thank you so much Wharfrat!  You give us something to aspire to!

[PsyBearknot]

Nice job. I do like the tip about the tyvk mailer sleeve!

[CatsAndBats]

Time to employ this!

[roscoe]

No need to wrap or protect your bags from the side of the cooker.

You DO however NEED to protect your cooker from your bags, by putting something on top of your bags to keep them from expanding and blocking your vent tube. I cannot stress this enough!
