MycoBox Golden Oyster Mushroom Growing Kit


Grow 30g - 70g of Golden Oyster mushrooms the easy way - grab this kit. After activating, leave it sitting on a shelf - out of direct sunlight - and the mushrooms just grow. 

  • 10ml mushroom culture spawn syringe included
  • 30 - 70g of edible mushrooms (over multiple crops)
  • Produces CO2 - place near plants to enhance growth

The kit is activated by you, so you won’t start producing mushrooms or CO2 before you’re ready.
It takes around 4 weeks to get your mushrooms, and you can continue getting crops of mushrooms for up to 8 weeks

You Get:

  • Sterile rice cake
  • Fruiting tray with vermiculite/polymer
  • Humidity tent
  • Swab
  • 10ml mushroom culture spawn syringe


How to Use

Step 1: Inject

Do not twist while injecting as this can block the syringe.

  • Injecting spores at 4 equally spaced sites around the top of the Mycobox (near to the edge). Swab each site with alcohol before injecting each of the 4 holes with 2.5mL of solution.
  • Inject as close as possible to the edge and push straight down.
  • Quickly tape over holes afterwards, covering any cracks (with sellotape or similar). That’s it!


Step 2: Incubate

Do not place in direct contact or too close to a heat mat or you will dry out/kill your mycelium!

  • Incubate the box somewhere warm and dark (26-28°C is ideal for most tropical species).
  • After a few days, small white spots of mushroom mycelium will start to grow.
  • Wait 2-3 weeks until the contents turn completely white (except for a small top layer which will not turn white as it is dry).


Step 3: Fruit (produce mushrooms)

  • Pour the contents of the small vermiculite bag into the tray and add around 1/2 a cup of boiling water.
  • Add lid and leave to cool for a couple of hours.
  • When fully cooled, open the lid slightly and drain off any excess water from the vermiculite.
  • Remove the lids from the tray and microbox and "birth" the cake (loosen the lid, invert the microbox and let it drop onto the vermiculite in the tray).
  • Place the whole tray and its contents carefully inside the plastic bag and close the top with paper clips or tape.
  • Place somewhere warm (22-24°C) where there is some light (but not direct sun).
  •  You should see mushrooms appear within 2-3 weeks.


Step 4: Harvest

  • Pick your mushrooms when they begin to open their caps. 
  • Add a bit more water to the vermiculite, close the bag again and you should get a couple more crops.
