Preparing the Straw and Coffee Grounds
Before your mushrooms can start to grow, you'll need to properly prepare the straw and coffee grounds. This requires a few different processes.
-
Prepare the Straw
- Cut the straw into smaller pieces, about 1-2 inches in length.
- Soak the straw in water for 24 hours to help soften and sterilize it.
- After soaking, drain the straw and let it sit for a few hours to allow excess water to evaporate.
-
Prepare the Coffee Grounds
- Collect used coffee grounds from your own coffee maker or ask a local cafe for their waste coffee grounds. (Note: You can store the grounds in the refrigerator to prevent mold until you're ready to use them.)
- Pasteurize the coffee grounds by placing them in a colander and pouring boiling water over them. This will help kill off any potential contaminants.
- Let the coffee grounds cool to room temperature before using them for your mushroom cultivation.
-
Creating the Substrate Mixture and Inoculation
Now that your straw and coffee grounds are prepared, it's time to create the substrate mixture and inoculate it with mushroom spores or spawn.
-
Creating the Substrate Mixture
Mix the chopped straw and pasteurized coffee grounds together in a large container or grow bag. The ideal ratio is about 70% straw and 30% coffee grounds, but this can vary depending on the type of mushroom you are growing.
-
Inoculating the Substrate with Spores or Spawn
- Wearing gloves, sprinkle the mushroom spores or spawn evenly throughout the substrate mixture.
- Mix the spores or spawn in thoroughly, making sure all areas are covered.
- Seal the container or grow bag and make small holes in the sides and top for air exchange.
-
Caring for Your Mushrooms
Once your substrate is inoculated, it's time to care for your mushrooms and ensure they grow successfully.
-
Maintain Proper Conditions
Keep the substrate container in a dark, warm area with temperatures around 60-75°F (15-24°C). The ideal humidity level for mushroom growth is around 90%. You can use a spray bottle to mist the substrate's surface to maintain humidity.
-
Harvesting Your Mushrooms
It generally takes about two to four weeks for your mushrooms to grow large enough to harvest. You'll know they're ready when the cap has fully opened and is beginning to separate from the stem. To harvest, simply twist and pull the mushroom gently from the substrate.
