    These are the synthetic filter discs that are featured on our Quick Colonizing 5-grain Jars. They are thick reusable and have a filter level of .2 microns, the highest level of filtration available.

    These synthetic filters discs fit precisely on any "wide mouth" 90mm canning jar which are commonly used by today's cultivators. Usage of these discs allows a fresh, constant air exchange while preventing the entrance of unwanted contaminates. Use them in place of jar lids, or just drill a hole in the lid, and place the discs under the lid.

    The self-healing injection port is made from our unique blend of RTV high temp silicone and a polymer additive mix. This blend allows for great adhesion and does not melt when inserting a hot needle.
