Fungi Farm Mushroom Windowsill Kit - Grey Oyster

Growing Instructions:
This kit is designed for indoor growing. Choose a clean area away from direct heat sources and draughts. Avoid direct sunlight to prevent overheating. Mushrooms prefer indirect, filtered light.
Please note: When opening the packaging, check if the substrate has grown completely white. If not, close the packaging with the plastic lid and store for 10 to 14 days at 20-25°C (68-77°F). Make sure that you leave the plastic bag around the substrate.

Step 1. Prepare the substrate
• Make five incisions, each 2-3cm long, in the plastic around the substrate.
• Water the surface with ¼ litre of water so it is moist.
• Leave the kit with the lid on at 20-25°C (68-77°F).
• After around 2 weeks, white pins will appear.

Step 2. Create the right environment
• Once pins appear, move the kit to a bright location at 10-15°C (50-59°F).
• Avoid direct sunlight to prevent overheating. Mushrooms prefer indirect, filtered light
• Lightly spray at least once a day. The surface must never dry out but should not become waterlogged.
• From the pins, small stems with grey dots will develop into mushrooms.

Step 3. Harvest
• Harvest clusters by twisting them out of the substrate, ensuring no flesh remains behind.
• Total harvesting time can last up to 3 months.
• Before eating, trim the mushroom to 1cm below the gills.
• The firmer stems are ideal for sauces or soups.
Please note: You may achieve up to 3 harvests. Before each new harvest, make 5 fresh incisions in the plastic.

For more information and guidance check out our Gardening Guides.

Harvesting: Take a mushroom between your fingertips and carefully pull it out with a twist of the hand. Do not pull out without twisting and do not harvest undersized mushrooms. Always water regularly to prevent the ‘cover compost’ from drying out.
