## Features

- GROW DUNG-LOVING MUSHROOMS INDOORS: Start growing your own dung-loving edible or medicinal mushrooms indoors! Kit includes everything you need to grow -- just add your own spore syringe or liquid culture!
- 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 & CASING LAYER: The monotub is designed with airflow and humidity controls and requires no high-tech additions. And the manure-based sterile substrates, injection port bag, and coco coir provide mediums for colonization, incubation, and growth.
- ALSO INCLUDES FILTERS & MICROPORE TAPE: We've also included self-adhesive filters and black micropore tape that fit over holes on the monotub lid and base. These are designed to keep out foreign spores and other contaminants while maintaining proper humidity, airflow, and gas exchange.
- 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.)
- KIT CONTENTS: (1) Max Yield Bins monotub; (3) Boomr Bag Sterile Manure-Based Substrate (5 lbs each); (1) Organic Sterilized Grain Bag with Injection Port (3 lbs); (1) Coco Coir casing layer (2 lbs); (2) sheets of 2” self-adhesive filters (12 pack); (1) roll of 1/2" black micropore tape (10 yards)
- IMPORTANT: Coco coir casing layer should only be added to your monotub once it's fully colonized and pinning.
