How to Grow Mushrooms in Hawaii

When you need mushrooms for a favorite recipe, nothing beats the satisfaction of using fresh mushrooms that you have grown yourself. Hawaii's perennially warm and humid climate make it an ideal location for growing most mushroom varieties any time of the year. Mushrooms thrive in moist, dark spaces and you can use any number of growing media, or substrates, including soil, sawdust, straw and even rice. With a few common household items and some mushroom spawn purchased from a local garden center, you can have a fresh supply of mushrooms in as little as two months.

Things You'll Need

Large pot
Straw
Rice
Soil
Sawdust

Plastic bag
Mushroom spawn
Tape
Spray bottle

Instructions

- 1
  Prepare your substrate of choice. If using rice or straw, fill a pot with water and bring it to a boil over high heat. Chop the straw into 3 inch pieces. Fill the pot with rice or the chopped straw and cook until tender. Drain and set aside until cooled to room temperature. If using sawdust or soil, moisten with water.

  Fill a plastic bag with prepared substrate. Place the mushroom spawn in the bag. If you have the dry mushroom spawn cakes, break them up into small pieces and scatter in the bag. Liquid spawn should be lightly sprinkled over the substrate to ensure even distribution. Lightly shake the bag to mix the substrate and spawn.

  Gather up the top of the bag and roll it down to tightly pack the substrate and spawn mixture. Tape down the top of the bag. Make several slits all over the bag. Place the bag in a warm, dark and moist area like a basement, garage or shed.

  Water the bag after the mycelium, a thick, white substance, starts to form. Once this forms, water the bag gently with a spray bottle once every two to three days. You can harvest your mushrooms in two to four months.
