TECHNICAL SPECIFICATIONS & CHARTS
Please select a variation to see its technical specifications
Use Boomr Bag in monotubs, filter bags, and outdoor beds. Or, grow mushrooms from the bag or tray in a humidity-controlled grow room or “Martha”-style mid size grow chamber.
Boomr Bags should be stored out of direct sunlight at room temperatures, and can be stored for several months before use.
Spawn to bulk ratio: Recommended mix is 1 colonized grain spawn bag per 2-3 Boomr Bags.
Use clean hands, latex or nitrile gloves, and sterile technique when using Boomr Bag to reduce the introduction of contaminants. Be sure to mix colonized grain spawn thoroughly into your 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.
