Every aspect of the Reishi Mushrooms growth is monitored from temperature, humidity, carbon dioxide, light intensity, and nutrient uptake making sure that these mushrooms result in the very finest examples of Reishi. The process of growing the mushrooms involves using 30cm slats of steamed (sterilized) wood from the basswood tree being placed in plastic bags with the Reishi spores placed on top. These bags are then placed in a perfect warm moist environment where the spores can develop and grow across the basswood slat. After 4 months the spores have developed sufficiently enough that the slats can be planted under earth in a growing medium where the temperature is maintained at 25°C. Over a period of about 3 months the mushrooms break ground and start to mature. Around August and October every year the Reishi Mushrooms are harvested to be selected for size. After inspection and drying the Reishi Mushrooms undergoes a process of cold percolation in order to extract the active constituents into tincture form. The cold percolation method employs a gradient circulation of the solution which keeps the plant ingredients in perpetual contact with the ethanol. This technique is faster and more efficient than maceration and ensures there is less waste of precious plant materials.
