Injectable Spawn Lid

A jar lid designed for convenient syringe access during mushroom spawn preparation. A self-healing injection port allows inoculation without removing the lid, while a filter provides gas exchange and helps limit airborne contamination.

• Purpose: Provides syringe access and filtered gas exchange for mushroom spawn jars

• Applications: Suitable for grain spawn preparation and maintaining mycelium in compatible jars

• Use: Fit onto a compatible jar containing prepared, sterilized grain. Using aseptic technique, introduce liquid inoculant through the cleaned injection port with a sterile syringe needle. The port reseals after needle removal, allowing the jar to remain closed; keep the gas-exchange filter unobstructed
