MicacleFarms spawn bags are used for mushroom cultivation. These bags are made of durable 3 mil polypropylene. They measure 4 x 3 x 18 inches, have a self-healing injection port for easy inoculation, and a 1.5 x 1.5 inch 0.2-micron filter which allows for the passage of air but not unwanted contaminates. They can be used in a pressure cooker, steam sterilizer, or autoclave.

Our spawn bags can be used for spawn production to inoculate bulk substrates like straw or compost. The breathable technology behind the mycobag provides gas exchange but excludes water vapor, so your spawn does not dehydrate and you can fruit your substrate right inside the bag itself.

These side-gusseted bags give a sturdy stand-up bag after filling and a strong bottom seal. They are reusable and can be sealed with an impulse sealer, taped, or tied shut at the ends. Each bag can easily hold 2-3 pounds of substrate. Miracle Farms grow bags are a superior and economical choice when it comes to growing mushrooms. Other sizes, filters, and quantities are also available.

My name is Brian, I'm in my 50's and own the company Miracle Farms. Much of my life has been spent in the US Army, since 1989 I have been stationed in South Korea (ROK) Germany, Fort Sill OK, and Fort Bragg, NC. My MOS is 13M FA, MLRS... multiple launch rocket systems.

So what does this have to do with mycology? Nothing...but around 2002 I developed an interest in mushrooms...all sorts of mushrooms. After having a life-changing experience with fungi, decided to get into the mycology field and have never turned back, it's been over 20 years now.

All the products I offer are made by me using years of experimentation, using my own tried and tested formulas. I do not follow the recipes of others, I make my own through trial and error. I literally have experimented hundreds of times getting my products such as my mushroom pre-mix nutrients power, agar recipes, spawn jars and bags, LC jars...perfect. When I finally do get it right, I do not share my formula with anyone. I'll list the most common ingredients on the label, buy secret ingredients, and stay secret.

I also add 24K Gold flakes to most of my products for several reasons. First, I believe it helps promote fungi growth, and second, in LC broths, the mycelium seems to use the flakes as a starting growth point. This makes the distribution of mycelium more even and helps to prevent clumping. Either way, I say this because I want to ensure you that your sample is not contaminated. I maintain a mushroom library of over 100 popular strains and test each one monthly excluding the cordyceps stains, they are tested twice a month. A visual inspection on agar is made as well as DNA testing as needed. All work is always done in the lab in front of a laminar flow hood (several)

Also, we do not sell strains of the happy variety on eBay, so please don't ask.


All orders are still being shipped the same day if payment is received by 6 PM EST. We are a Florida-based business and although the hurricane did not shut us down, our staff was not so lucky. Currently, it's just me, Brian, filling and shipping all orders. My main goal is to get out a quality, clean room-produced product, every day, 7 days a week. That said, I will not be able to reply to every question a customer may have. If you placed an order, it would be ready to ship the same day...however, if you order on a Saturday, your order will not go out until Monday. If there are any issues with your order, please return it to the address provided in your package, I will personally reship your order the same day I get it, and as always, I will include a gift for your troubles. :) I appreciate your business and thank you.
