This is the primary “soil” used in mushroom growing. Grains such as corn, rye, oats, milo, millet, etc. are used as a nutrient-rich growing medium for spores, liquid culture, and agar slices. To make grain spawn, the grains are hydrated and sometimes boiled, until they soak up as much water as they can hold. Then these grains are bagged and pressure cooked until they are fully sterilized, or else they’ll get moldy. The grain bags that we sell are free of any competing microorganisms or contamination, allowing your mycelium to thrive and grow without any competition! After your spawn has fully colonized the grain, it is wise to mix it with substrate for optimal growth.

Congratulations, you are now a proud owner of the best all in one grow bag. We recommend that you keep the bag at room temperature for at least 24 hours before inoculating. DO NOT discard the box as that will be used throughout the growing process. There is no need to use the bag right away, it can be stored, sealed inside of the vacuum bag and inside of the box for up to 6 months.
Once you are ready to inoculate the bag, follow the instructions as follows.
Make sure to have the following items for pre-inoculation prep:
- All in one grow bag (included)
- Alcohol wipe (included)
- Scissors (not included)
- Liquid culture syringe (sold separately)
- Lighter or blow torch (not included)
- 2-3 paper clips (not included)
When you are ready to inoculate your bag, make sure that you have all of the necessary items on hand. Tear the lid off the box at the perforation and discard. Keep the vroom vroom bag in the lower half of the box during growth as this will shield the bottom of the bag from excess light that may cause side-pinning. The vroom vroom bag itself comes inside of a vacuum sealed bag to maintain freshness. Using a pair of scissors, carefully cut only the vacuum sealed bag. During this process DO NOT damage the vroom vroom bag. The vacuum bag can be placed in your recycle bin
