Give developing mycelium a clear view and a stable home. This lid is built for the colonization stage so you can check on your substrate without cracking the tub open. This way, humidity stays put, contamination risk is reduced and colonization moves along undisturbed.
It's molded from durable, food-safe plastic and holds up to grow after grow of reuse. Because it's clear, you can track colonization at a glance instead of guessing what's happening under a lid.
It's also shorter than our standard lid, so it takes up less vertical space on the shelf, worth it if you're stacking totes onto tight shelves.
This fits Boomr Bin grow chambers only. It's the lid alone; no bin, substrate, or spawn included.

How to use

Secure the Colonizing Lid to your Boomr Bin after mixing your colonized grain spawn and substrate. Its low-profile design creates a compact, enclosed environment for colonization while making it easy to stack or store multiple bins. When you're ready to introduce fruiting conditions, swap the Colonizing Lid for the standard Boomr Bin lid.

Note: to maintain an ideal environment do not open the lid during colonization.
