SubOne brand substrates are crafted from the highest quality ingredients in formulations that our team has been making and using for over 35 years in commercial mushroom production. Each fully-automated batch is sterilized in autoclaves under high pressure and packed in a cleanroom, tested, date coded and tracked to ensure consistency and purity. SubOne substrates are the most contaminant free product on the market and will provide the perfect growing environment for the fast colonization and high yields for a wide variety of specialty mushrooms.
