The proven 7-Step method for premium oyster mushrooms
At Spora Farm, we use an advanced, proven cultivation process that ensures consistent quality and optimal growing conditions. Our method combines traditional farming wisdom with modern agricultural science to produce the finest oyster mushrooms.
We use premium quality paddy straw as our primary substrate. The straw is carefully selected - harvested and stored for at least 90 days to ensure optimal nutrient content. It must be completely dry with a rich golden-brown color.
Using industrial cutters, the paddy straw is cut into uniform 3-4 inch pieces. This uniform cutting helps in better nutrient release (lignin and cellulose) required for mycelium growth and makes the bagging process more efficient.
The prepared straw is bagged in 10kg jute bags and soaked in water for 5 hours, then drained to achieve 20-30% moisture. Bags are then sterilized using steam at over 100°C for 2 hours in our semi-autoclave steam room, killing all pathogens and contaminants.
Using 5kg polypropylene bags, we layer 3.5kg of sterilized substrate with 200g of high-quality oyster mushroom spawn in 5 layers. Small holes are created and filled with sterilized cotton to allow proper air circulation for mycelium growth.
Inoculated bags are hung in our controlled environment fruiting room for 21 days. During this period, mycelium colonizes the entire substrate forming a thick mycelial mat. Temperature (20-24°C) and humidity (70-80%) are carefully maintained.
After 21 days, cotton plugs are removed to initiate fruiting. Within 5-7 days, mushrooms begin to sprout. We harvest when caps are fully opened but edges are slightly curled, ensuring peak freshness and flavor. Each mushroom is carefully hand-picked to avoid bruising.
We maintain strict hygiene standards with regular fumigation, use of nets to prevent contamination, and constant monitoring for pests and mold. All staff use sterilized masks and gloves. Temperature and humidity are monitored 24/7 for optimal conditions.
