12 Pack Rust Proof 304 Stainless Steel Grain Spawn Wide Mouth Jar Lids for Mushroom Cultivation

$74.99

ProLid professional series wide mouth stainless steel mason jar lids are engineered for reliable repeated use and lasting durability. Designed to make hundreds of runs through the autoclave or pressure cooker. ProLids offer a combination of unique features, not found anywhere else. Made of 304 Stainless Steel metal to prevent the rusting of standard metal lids. A solid one-piece design and construction makes them simpler to use and clean. Each lid includes a fitted silicone seal that stays in lid when held upside down. These lids feature a huge 1/2″ heavy duty self-healing injection port and a high quality 0.45 PTFE filter sticker. These industrial strength components mean you will rebuild them less often. Even when you do, replacing an injection port is super easy, because they fit snug and require no sealant or mess. We sell replacement parts for all our lids. PLEASE NOTE: This version is designed specifically for grain spawn cultivation (not liquid culture), because they feature a PTFE filter sticker, which cannot be held upside down with liquid. If you would like lids for liquid culture, which are leak proof upside down, checkout our other listings.
