Our Process

We take no shortcuts. This provides perfect results. We don't accept anything less than perfect.

Here's my process:

  1. [Step 1] - 24 hour soak w/ gypsum.
  2. [Step 2] - 15 minute simmer.
  3. [Step 3] - 60 minute dry off.
  4. [Step 4] - Fill .2 micron Unicorn.
  5. [Step 5] - 90 minute PC @ 17psi.
  6. [Step 6] - Seal bags w/ flowhood.

Many people take shortcuts to speed up their production. Many use "No Soak" or "No Simmer" Tek.


Patience + Care = Phenomenal results.


Just bring your own (clean) spores/culture.

    What’s your time worth?

    I’ve got a pressure cooker, a vacuum sealer and plenty of experience making jars and bags. But at this price, why bother? What’s your time worth? I have better things to do than soak, drain, weigh, deal, pressure cool and cool bags.

    Haven’t had a single contam issue with any of the 6 bags I purchased. Will definitely buy more, especially since Myco Zombie always sends out discount codes!

    Just buy them already.


    Waste no more time looking and wondering and worrying if they’ll work. I already did that. They do.

    Just buy them already.

    If you need further persuasion to NOT just buy them already, I’ll tell ya.

    I bought six of these grain bags here and bought four of the all-in-one kIts elsewhere.

    I will NOT buy all-in-one kits again. 💴 🔥 🪽🪽🪽

    Not one of thLike ALL six bags way better than I didn’t expect.

    The all-in one bags are, well, I’m still waiting to see.

    UPDATE: previously I gave an overall five star review but I only gave three stars on the shipping of course I didn't use customer service so I didn't initially rate customer service now I'm giving them a five star for all. The reason I initially gave the shipping three stars is because the box came severely beat up Open the contents inside were exposed. so I posted a picture of the damaged shipping box and unfortunately I could only post one picture because the contents look mostly fine. After sending the information and several pictures to the seller I was very very surprised this morning to discover they were shipping me replacement products for anything that may be questionable. I did not ask for anything to replace they just went ahead and did it. AMAZING!

    Also The product looks not to wet or too dry.
