The Mushroom Grow Bag is a completely self contained environment for the incubation and fruiting of grain loving mushrooms.

New model Mushroom Grow Bags begin shipping on 7-01-02. This new bag design proves to be more reliable as it allows for spore or culture syringe inoculation directly into the substrate material. The bag is shipped with all air removed for easy packing and bags should arrive in better condition.

Each Bag includes a pre-sterilized mixture of substrate material specially designed for grain loving mushrooms. A filter patch is attached to the bag to allow for gas exchange during colonization and fruiting. Now shipping with self-healing injection sites located at substrate level. The bags measure 4" wide, 3" deep, and 18" tall.

Please Note: The Mushroom Grow Bag does not come with Spore Syringes.Spores are sold seperately and can be purchased here.

Directions for use:

Upon arrival, inspect your bag for punctures or tears, if any are noticeable, contact us to arrange for a replacement to be shipped. Unfold the bag, allowing the extra bag material to stand straight up as pictured in Figure 1.

Locate the small foam disk sealed and attached in a plastic housing near the base of the bag. This disc is the self-healing injector site. IMPORTANT -Sterilize a small section of the outside of the bag directly over the foam disc with an alcohol soaked wipe. With the same alcohol soaked wipe, sterilize the needle on your culture or spore syringe.

Inoculate the substrate with spore syringe solution by inserting the needle through the foam disc at the previously sterilized spot. Fully insert the needle at an angle as pictured in Figure 2. Squirt 1cc of spore or culture solution directly into the substrate material . Remove the needle and reinsert through the injector site at the opposite angle. Again inject 1cc of spore solution directly into the substrate material. Inoculating twice, at opposing angles, towards the sides of the bag is recommended for faster colonization and even inoculant distribution.

DO NOT insert the needle through the white filter patch found near the top of the bag.

Place the Mushroom Grow Bag in a dark location and incubate at species specific parameters. It is recommend to store the Mushroom Grow Bag fully extended as pictured in Figure 1 as developing Mycelia will give off gases that will slowly expand the interior of the bag. This ballooning effect is crucial for proper air exchange and culture development.

Note: During drier summer months it is advisable to store Mushroom Grow Bags in a humid location. Excessively dry environments may draw moisture from the bags.

Because germination and colonization will begin in the interior of the substrate material it may between 14-20 days for you to notice the spreading of colonizing mycelium towards the outside of the bag. Typical colonization time is 21-30 days for most species and strains.

When colonization is 90% or 100% complete, move bag to a location with indirect light (indoor light or filtered sunlight is best). Allow the bags to receive 12 hours of indirect light per day (direct fluorescent lighting works as well).

The bag is never opened until harvest!

To harvest, open at top and reach down the length of the bag to crop. After cropping is complete, spray a light mist of distilled water down the insides of the bag. Fold the top of the bag down over itself and hold closed with a cloths pin, 'chip saver,' or similar clip. Closing and misting in this manner can help increase the possibility of up to 3-4 flushes.

Tested and proven, this all you need to begin your journey in the art and science of mushroom cultivation.

The pictures at right display the typical development of grain loving mushrooms in the Mushroom Grow Bag.

Figure 1 is the bag pictured before spore or culture inoculation. Figure two illustrates spore or culture syringe inoculation of the bag through the enclosed self-healing injection port. Figure 3 is a side view of a colonized and fruiting bag. Figure 4 shows a recently opened bag, ready for harvest.
