THE ART AND SCIENCE OF DESERT MUSHROOM CULTIVATION

Our cultivation process is a carefully orchestrated symphony of biology, technology, and sustainable practices. Here's an in-depth look at how we grow our premium mushrooms in the heart of the desert:

  1. Substrate Preparation: Our proprietary substrate mix is the foundation of our mushrooms' success:

  • 60% Water: Carefully pH-balanced and purified using activated charcoal water filtration to ensure excellent flavor and safety

  • 30% Cellulose: A blend of sawdust, recycled paper, and locally sourced plant waste

  • 15% Nitrogen: Coffee grounds from local cafes, organic alfalfa

  • 5% Mineral additives: To mimic the diverse nutrient profile of natural forest floors

70% of our substrate ingredients come from upcycled waste products, supporting local industries and reducing landfill waste.

  1. Sterilization and Inoculation:

  • Substrate is sterilized in large autoclaves to eliminate competing organisms

  • In our laminar flow hood, we introduce carefully selected mushroom cultures to the sterile substrate

  • The inoculated substrate is then sealed in specially designed grow bags

  1. Incubation:

  • Bags are moved to our climate-controlled incubation rooms

  • Over 2-4 weeks, mycelium colonizes the substrate, creating a dense, white mass

  1. Fruiting:

  • Once fully colonized, bags are moved to fruiting rooms where environmental conditions trigger mushroom formation

  • Lighting, temperature, humidity, and CO2 levels are precisely controlled to mimic ideal natural conditions

  • For some varieties, we simulate desert day-night cycles to enhance flavor and nutrient density

  1. Harvest and Processing:

  • Mushrooms are hand-harvested at peak maturity

  • Immediately processed in our on-site clean room for maximum freshness

  1. Organic Waste Feeds Local Gardens:

  • The spent substrate becomes a nutrient-rich compost after harvest

  • Contains an average of 25% organic matter and 58% moisture

  • Rich in nitrogen (1.12%), phosphate (0.67%), potash (1.24%), calcium (2.29%), magnesium (0.35%), and iron (1.07%)

  • Ideal pH of 6.6 and a carbon-to-nitrogen ratio of 13:1

  • Used in our desert restoration projects and offered to local gardeners and farmers

Our Technology

EMPLOYING CUTTING-EDGE TECHNOLOGY TO MAINTAIN THE HIGHEST STANDARDS OF QUALITY AND EFFICIENCY

Sustainable farming practices are augmented by the use of current technology from mycelium inoculation in a sterile cleanroom environment to temperature, light, and humidity regulation using IoT sensors and feedback control equipment. We leverage the use of:

  • Laminar flow hoods ensure sterile conditions for culture work

  • IoT sensors monitor all environmental parameters in real-time

  • AI-driven climate control systems optimize growing conditions

Fun fact! Our cultivation process mimics and accelerates natural decomposition cycles. In nature, fungi can take months or years to break down cellulose. In our controlled environment, we achieve this in weeks!
