About This GROW DUNG-LOVING MUSHROOMS: Start growing your own dung-loving edible or medicinal mushrooms indoors. Our beginner-friendly Boomr Bin Mushroom Monotub makes mushroom growing easy! JUST ADD YOUR OWN SPORES: Created by mycologists, this starter kit is equipped with everything you need to grow dung-loving species at home. (All that's required is a spore syringe or liquid culture!) INCLUDES MONOTUB, SUBSTRATES & FILTERS: The monotub design is optimized for all growers – whether you prefer lo-tech grows, or want to connect automated upgrades (like fresh air fans and humidity controls.) The manure-based sterile substrates, injection port bag, and coco coir provide mediums for colonization, incubation, and growth. We've also included self-adhesive filters that fit over holes on the monotub lid to keep out foreign spores and other contaminants. SPAWN TO BULK RATIO: We recommended 1 lb of colonized grain spawn for every 5 lbs of Boomr Bag sterile substrate. (Higher inoculation rates may improve your success.)
