Microppose Adhesive Injection Ports for Mushroom Cultivation 18mm

These are the daddy of all injection ports, made by Microppose, trusted by pros, and loved by anyone who’s ever jabbed a syringe into a grow bag. Money literally can’t buy better. Some even say they seal better than the original Unicorn bag ports (we’re not arguing).

We’ve been using these for years and gone through tens of thousands - they never fail. Perfect for liquid culture lids, mushroom grow bags, or any setup where sterility actually matters. If you’re drilling lids or building bags, these are non-negotiable.

• Self-healing magic - reseals like nothing happened
