We are delighted to announce the official launch of our optimized formula, now available for purchase. Following extensive research and development, we are thrilled with the exceptional results achieved. This refined formula is not only user-friendly but has also demonstrated remarkable performance, colonizing all ten 16oz test jars within an impressive eleven-day period. Ideal for Liquid Culture applications, including spore germination, culture expansion, growth timeline acceleration, mid-term storage, and master culture, this formula is also perfectly dosed. Our measurement system is designed with the standard 16oz Mason Jar in mind, ensuring ease of use. The formula is precisely proportioned to fill four 16oz jars with the exact required headspace for growth, while the entire bag can yield eight 16oz jars. For single-jar applications, one tablespoon (1/8 of the pouch) is all you need. Experience the benefits of simplicity and consistency with our formula. Try it and discover a new standard in mushroom cultivation.
