Psilocybin Grow Bags

Psilocybin Grow Bags

All-in-one mushroom grow bags with a layered design that features a layer of sterilized grain for rapid mycelium growth and a layer of sterile coco coir substrate for fruiting. Designed to make cultivating mushrooms easier than ever!

The filter patch is a slip-in tyvek filter that you can place between the gussets of the bag before sterilization. It filters the air that comes into the bag during cool down, keeping out contaminants such as mold spores.


A perfect blend of sterilized rye grain, coco coir, vermiculite, gypsum and coffee. This all-in-one substrate is designed by mycologists to maximize speed and colonization of the mushroom mycelium. It is the fastest growing self healing mix on the market!

This bag is autoclavable and has a 0.2 micron filter. This allows for optimal air exchange without risk of contamination. It is the optimum size for a variety of manure loving mushrooms.

Once you inject your spores or liquid culture into the injection port, the bag will begin to colonize. It can take anywhere from a few days to a few weeks for the mycelium to fully colonize.

Once colonized the bag should be closed off, and the injection port sealed with a piece of wire. This will keep the bag from being contaminated by dust or other spores that could have entered during sterilization. The bags can be reused for spawn blocks or fruiting bags, but it is recommended that they be sterilized new each time.

Injection Port

These 8″ x 5″ x 19″ autoclavable gusseted bags are designed with a foam self-healing injection port for use with a spore syringe. They also feature a 5 micron filter patch that blocks airborne contaminants and provides for even gas exchange.

Once you have your spores ready (we recommend waiting a week post-delivery to ensure the bag didn’t get compromised during shipping) simply inject into the injection port with a sterile needle. It’s best to sterilize your needle with alcohol before each use.

After inoculation leave the bag undisturbed in a dark place out of direct sunlight. Within a couple weeks you will notice the grain transforming into mycelium.

It’s that easy, you can literally do nothing but wait for the magic to unfold! This is a much faster and simpler method of growing mushrooms that eliminates all the guess work and frustration that comes with conventional methods.

Filter Patch

The filter patch allows mycelium inside the bag to breathe, while preventing competing organisms from entering. It’s a key component of any grow bag, and can be purchased from multiple different manufacturers. It’s important to note that not all filters are created equal – some may have larger pore sizes than others. A 0.2 micron filter is the recommended size for spawn bags and substrate bags, as it offers optimal air exchange while reducing competitor organisms entering your substrate.

Filter patch bags are made of autoclavable polypropylene, and are designed to be used with sterilized substrates. They can be reused for spawn blocks or fruiting blocks, but should always be sterilized before reusing them. This is because the integrity of the bag and the filter patch degrades with each sterilization cycle, increasing the likelihood of contamination. This is a problem because it can cause your mushroom crop to die before it’s ready for harvest. This can be prevented by using a new filter every time you sterilize your bags.


You’ll want to use a bag that is both autoclavable and has a filter patch large enough for proper air exchange. Make sure the bag is sterile by cleaning it with alcohol before inoculating. It also helps to have a sterile work area when working with the bags, especially for the injection process.

Inject the bag with spores (instructions will come with your kit) or mycelial culture using the black self-healing injection port. Clean the injection port with a sterile alcohol wipe and flame sterilize the needle of your syringe before inserting it.

Once the bag has been injected, let it colonize in a dark place. It may take 3-4 weeks for the rye grain substrate to fully be covered with white mycelium.

It is important to not disturb the bags too much during this colonization phase. Once the mycelium is fully established, you can start inducing fruiting by moving the bag into a warmer, brighter location with high humidity.Psilocybin grow bags
