Choose a mushroom species suitable for indoor growing, such as oyster, shiitake, or button mushrooms
Buy a mushroom grow kit or spawn from a reliable supplier
Prepare a clean growing area with low light, fresh air, and stable temperature
Use a suitable growing medium such as straw, sawdust, coffee grounds, or compost, depending on the mushroom type
Sterilize or pasteurize the growing medium to reduce contamination
Mix the mushroom spawn into the prepared growing medium
Place the mixture into a clean container, bag, tray, or bucket with air holes
Keep the growing medium moist but not waterlogged
Maintain the recommended temperature for the mushroom species
Keep humidity high by misting regularly or using a humidity tent
Provide indirect light if required by the species
Allow fresh air exchange to prevent mold and support healthy growth
Watch for pinning, then continue maintaining moisture and humidity
Harvest mushrooms when caps are fully formed but before they drop spores
Clean the growing area and remove any contaminated material
Repeat with fresh substrate for another growing cycle
