Get Started Growing Mushrooms Today!

Our ready-to-use mushroom grow kits include everything you need to start your mushroom cultivation journey. Our kits aren’t just “Spray and Grow” - our hands-on approach allows you to experience and familiarize yourself with the basics of mycology, the lifecycle of mushrooms, and the art of fruiting mushrooms so you can apply those skills to your future grows. 

Frequently Asked

What is included in the all-in-one mushroom grow kit from RMS?

The RMS all-in-one mushroom grow kit includes a pre-sterilized substrate bag, a liquid culture syringe, and an accessory kit for your grow bag with everything you need to grow. You should also receive an email with a digital copy of our grow guide with specific instructions on how to use your kits. 

How do I inoculate the substrate bag?

First, wipe the injection port and substrate bag with the provided alcohol wipe. Then, using the liquid culture syringe, inject the culture into the bag through the square injection port. Be sure to follow the specific instructions provided in your kit for the best results.

Where should I store the inoculated substrate bag during colonization?

Store the inoculated substrate bag in a dark, warm place with a consistent temperature between 70-75°F (21-24°C). Avoid direct sunlight and ensure the environment is clean to prevent contamination.

How long does the colonization process take?

Colonization typically takes 2-4 weeks, depending on the mushroom species and environmental conditions. You'll know the substrate is fully colonized when it is completely covered in white mycelium.

What should I do if I see contamination in my substrate bag?

If you notice any contamination (discolored spots, black or green mold, unusual smells), you can contact us to confirm if it is contaminated. Contaminated bags should be discarded safely. Please include your order number and any information on when you inoculated your bag as this helps our team identify potential issues. 

When and how do I move the colonized substrate to fruiting conditions?

Once the substrate is fully colonized, place it in a humidity-controlled environment with indirect light to prepare for fruiting. Follow the specific instructions in your kit on how to set up optimal fruiting conditions, and feel free to reach out if you are having trouble. A grow tent or a monotub with proper ventilation and humidity can also be used. 

How do I maintain the right humidity and temperature during fruiting?

To maintain a humidity level of 85-95% and a temperature between 60-70°F (15-21°C) during fruiting, place the bag in an area with indirect sunlight or artificial lighting and use a spray bottle to mist the inside of the grow bag or fruiting chamber bag. You can also use a  hygrometer to monitor humidity levels. Ensure proper ventilation to provide fresh air exchange by cutting holes or slits in the bag as noted in our grow guide

When can I expect to see mushrooms starting to grow?

Mushrooms typically begin to form (pinning) within 7-14 days after moving the colonized substrate to fruiting conditions. The time may vary depending on the species and environmental conditions, so refer to the specific fruiting guides for each mushroom kit in our grow guide

How do I harvest the mushrooms?

Harvesting your mushrooms requires some familiarity with the look of the mushroom itself - our grow guide includes images of fruits at full maturity. For most mushrooms, this is before they release spores, when caps begin to flatten, or when the veil breaks from the stem, exposing the gills.  Gently twist and pull the mushrooms from the substrate to remove them, or carefully cut with a clean knife. 

How many flushes or harvests can I expect from the kit?

Most all-in-one grow kits can produce multiple flushes of mushrooms. After harvesting the first flush, continue to maintain the right humidity and temperature to encourage additional flushes. Typically, you can expect 2-3 flushes per kit, but each flush will decrease in yield by about 50% from the previous flush.

What should I do with the substrate after it stops producing mushrooms?

Once the substrate stops producing mushrooms, you can discard the bag and use the block in your garden or compost pile where it can be composted and used as one of the best soil amendments around! We recommend breaking up the block before adding to your compost or garden. 

Who can I contact for additional support or questions about my RMS grow kit?

For additional support, contact Redwood Mushroom Supply directly through their customer service email provided in your kit's instructions. They can offer guidance and troubleshooting for your specific needs.
