Lids - mushroom spawn/LC jars w/ gas exchange and self-healing injection ports

Description

Regular-mouth (2.75") or wide-mouth (3.38") lids for mushroom liquid culture/spawn jars. Fits any size (half-pint, pint, quart, etc.) jar that has an opening with one of these diameters. Each lid has a self-healing injection port and Tyvek-covered gas exchange port. Rings not included.
ABOUT:
Each reusable lid has 1 self-healing injection port for inoculation and 1 Tyvek-covered port to encourage gas exchange. They can be pressure-sterilized and are suitable for mushroom spawn, substrate, or liquid culture jars. The Tyvek-covers for the gas exchange ports are attached using high-temp silicone caulk and will remain attached through many sterilizations.
We occasionally get asked why we flip the lids upside down from their typical position when used for canning fruit and vegetables. We do this for three reasons: 1) the lids are MUCH easier to remove after having gone through a pressure- or steam-sterilization cycle; 2) there is no impact in the lid's ability to keep out contaminants when flipped over; and 3) when dust or other contaminants settle on the lid during the myc's incubation period, it has a tendency to collect in the lid's upturned lip on its outside edges rather than at the raised portion of the lid where the injection and gas exchange ports are located.
The only lids we sell that we setup in "standard canning" position are those for our filled liquid culture jars where we believe it is more important to have a leak-proof transit than an easier to remove lid.
WHAT'S FOR SALE:
Mushroom Jar Lid(s) (regular-mouth or wide-mouth) with 1 self-healing injection port and 1 Tyvek-covered gas exchange port per lid.
Rings not included.

WHY STILLHOUSE HOLLOW FARMS?
We are passionate about what we do and seeing others succeed. A small veteran and family-owned business, we realized early on how difficult it is to maintain a farm when it seems like you need to mono-crop and run a 3000 acre operation just to stay afloat. As a consequence we downsized and sought out niche ag markets upon which we could have a more sustainable and meaningful impact. We've never looked back! Thank you for your support!
