1 x 1kg of Sterile Millet in a mushroom filter patch and self sealing injection port bag, heat sealed, 10 x 8.5cm x 50cm High quality heavy gauge 0.06mm substrate bags with 0.02 micron filter patch, allowing air to pass in but not bacteria. Suitable for all types of liquid culture and spores. Here at Foragers Table, unlike other growers, we use Millet rather than Rye Grain for our mushroom spawn. This Millet seed gives many times more inoculation points when added to your substate of choice for a quicker more even colonisation. Our Millet seed is hydrated then sterilised at 15 PSI, then heat sealed in our laminar flow hood to ensure this seed is contaminant free for its journey to you, giving the greatest change of successful inoculation by you. Note 1. The bag with your Hydrated Millet with it’s injection port and filter patch are pre installed before sterilised together. 2. Make sure your syringe needle is sterilised before entered into the injection port. 3.We do keep a small stock of sterile Millet but try to make to order for maximum freshness so please allow 3 days for this.
