TheMooseZeus Posted April 25, 2022 Hey all, My block of coco coir has been sitting out the front of my house for sometime (months), still dry. Is pasteurisation going to cut it or are contaminants going to run wild and should I just buy another block. Has anyone had success with an older block of coir or is it important that it's clean. Cheers all! Share this post Link to post Share on other sites
