Instructions for Starting Your Grow-it-Yourself™ Mushroom Kit
Your kit has a bag of live spawn and one of dry substrate mixture. Spawn contains living fungus fibers we call mycelium. Use the spawn within a few weeks of acquiring it – ideally within a few days. If you need to keep it for a while, refrigerate it.
The spawn comes in a growing bag with a filter patch that lets air circulate. You add water, substrate mixture, and other ingredients to the spawn bag, then seal it and let the mix incubate for a few weeks. All of our GIY mushroom kits start this way. Later in the process you will need different instructions for each species, which you will find in other articles in this section.
To start, in addition to the spawn and substrate mix in the kit, make sure you have
Choose a clean, quiet place to work, like a kitchen counter or table. Try to minimize wind and disturbances that can raise dust. Wash your hands well. If convenient, wipe them with alcohol or hand sanitizer. Then follow these steps:
Place the bag gently in a dark but well-ventilated place where you can check it easily to see the fine, white mycelium spread through the substrate. You can keep it in a lighted area — like your living space — in a paper bag or box to shade it. Keep the box top open for air, though. Don’t smother it in a tight space like a drawer. A temperature around 65°F is ideal, but it will do fine between 50°F and 80°F.
