Additional Information

Blue Oyster Growth Phases

Your Spray and Grow Mushroom Kit contains a bag with colonized block of mushroom mycelium. It will appear whiteish to different shades of light brown depending on the variety of mushroom. Don’t worry it is not mold. It is healthy Mycelium from which your delicious mushrooms will grow! Follow the directions below to enjoy the freshest gourmet mushrooms possible. Always thoroughly cook your mushrooms before eating.

  1. Open the front of your kit by completely removing and disposing of the perforated disk located on the front of the box.
  1. Slice a large ‘X’ into the plastic with a sharp knife or scissors. Make sure that the ‘X’ is cut across the entire opening.
  1. Open the top of your box and remove the sprayer and instruction booklet. Close the top of the box. Fill the sprayer with tap water and generously spritz the plastic where you sliced your ‘X’ shape. Spritz your kit 2 to 4 times daily – If you’re in a particularly dry climate, spritz more often and consider making a humidity tent. (See directions for “Making a Humidity Tent” below) Your mushrooms will thrive at higher humidity levels. If the humidity is too low your mushrooms could dry out and not produce to their full potential.
  1. Place your Spray & Grow Kit in the most humid part of your home and outside of direct sunlight. We like putting ours in the kitchen and close to the sink. Once open and watered, the mushroom mycelium will sense the oxygen in the air and start to produce mushroom “pins” which are tiny “baby mushrooms”.
  1. Typically it takes 5-14 days for the pins to form. Once pins begin to form, your mushrooms will begin to grow quickly. Keeping your mushrooms in a warmer environment (70+ degrees) will allow them to grow quicker. Mushrooms should be ready to harvest 2-5 days after the pins begin to form.
  1. Harvest your mushrooms by cutting them flush at the box. Alternatively, they can be harvested by pulling them off the box with a simple pull and twist motion.
  1. Enjoy your mushrooms by cooking them in your favorite mushroom dish. You can also visit the recipe section of our website where you will find some of our favorite mushroom dishes along with several cooking videos and tips.

Please note, the sooner you cook and consume your mushrooms the better. Mushrooms always taste better when fresh! If you can’t use them immediately, we recommend storing them in the fridge in a paper bag. Your mushrooms will remain fresh for a few days. You can also dehydrate your mushrooms to increase their shelf life.

Mushrooms thrive in high humidity. A good rule of thumb is 70% to 90% relative humidity. Your local hardware store will sell inexpensive humidity gauges that will readily indicate the current relative humidity. If you find that the humidity in your home is low, you can make a humidity tent for your Spray & Grow Mushroom Kit. Humidity tents are quick and easy to make and are useful in keeping the humidity high while your mushrooms grow. Consider a humidity tent In dry climates (such as winter in northern parts of the country) as the humidity will be much lower than spring and summer months. In any dry climate, regardless of the season will require more frequent watering and a humidity tent will help maximize mushroom growth and yield.

How to make a Humidity Tent:

Simply take a clear plastic bag and cut several 1/2-inch holes in it. And place over your mushroom kit. Be sure to leave plenty of space for your mushroom to bloom. Don’t worry if the bag lays on the mushrooms as they grow. Mushrooms are amazing and strong growers and will lift the bag while it grows provided it remains loose fitting. Feel free to adjust the bag as needed. You can remove the bag for watering and to check on your mushrooms. Just remember to place the bag over your kit when done.

IMPORTANT NOTE: Mushrooms create CO2 and inhale oxygen while growing. They will not grow to their full potential if there isn’t adequate airflow. Your mushroom humidity tent needs to have several holes in it to not only release the CO2 but to also allow for fresh air to come inside.  When using a humidity tent, while spritzing your mushrooms daily as directed, spritz the inside of the humidity tent as well to maintain the humidity. Your mushrooms will thank you and you will enjoy a more bountiful harvest!  

Congratulations! Your delicious oyster Mushrooms are ready to harvest and enjoy! Knowing the right time when your mushrooms are ready is important. One telltale sign that they are ready is when the mushroom caps are still slightly folded downward or have just flattened out. If the caps start to fold upward, then it’s time to harvest right away. Harvest the entire bloom of mushrooms at once by cutting them flush at the box. Alternatively, you can simply pull them directly off the box with a pull and twist motion. If you have questions on when to harvest, or anything else feel free to send us a photo at and we’ll gladly help.

Stir-fry: Oyster mushrooms are a great addition to stir-fries. Cut them into bite-sized pieces and cook them with other vegetables and proteins such as tofu or chicken. Add some soy sauce, ginger, and garlic for flavor, and serve over rice or noodles.
