North Spore ‘Boomr Bag’ Manure-Based Sterile Bulk Mushroom Substrate

Over several years, it has been perfected for dung-loving mushroom species and is widely trusted by mushroom growers. Use your Boomr Bag in monotubs, outdoor beds, or to grow mushrooms from the bag in a humidity-controlled grow room or Martha setup. (Higher inoculation rates may improve your success.) Be sure to mix your grain spawn thoroughly into your Boomr Bag substrate. It is best practice to wait a minimum of 1 week after arrival before using sterile substrates to ensure they were not compromised during transit. Storage: Boomr Bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use.
