Mushroom Substrate Jars

These jars colonize quickly and completely, getting you across the line and ready for fruiting or transfer to bulk substrate in the shortest possible time. We ship them to you sterilized and pre-watered to field capacity and we only make the jars after you order so you get the freshest possible substrates. Inject with your favorite clean liquid culture solution, add cloned tissue culture or do a grain transfer and watch the mycelium RIP through the jars!
