Gorilla Mushrooms™ 3-Pack Wide Mouth Mason Jar Lids – Injectable, Autoclave Safe, With Injection Port & Filter

If you're into mycology, these lids are a game-changer.

This is a 3-pack of modified wide mouth mason jar lids from Gorilla Mushrooms™.

They're not your standard lids—they've been bored out and fitted with a self-healing injection port and a filter.

That means you can inject your liquid culture or spore syringe right through the port without letting any contaminants in, and the filter allows for gas exchange.

They're 86mm, which fits standard wide mouth jars.

And yes, they're totally safe to throw in the autoclave or pressure cooker for sterilization.

The MPN is MYCOLIDWM.

No more fiddling with foil and tyvek; these lids make the whole grain spawn process so much cleaner and easier.

Just screw them on, sterilize, inject, and watch your mycelium take off.
