You can either make a ton more grain spawn, or add it to a bulk substrate to finally get some mushrooms! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. I prefer the ‘pro’ lids because they require less maintenance as every now and then you need to replace the polyfill or re-set the ports, the epoxy makes these lids pretty permanent. This will allow the grains to absorb water, and will cause many contaminants to sprout, making them more susceptible to being killed through sterilization.

You can also inoculate the grain jar without even opening the lid, by simply injecting the liquid culture right though the filter on the top of the jar.

I like to do any contamination sensitive work in front of a laminar flow hood, in which inoculating grain spawn definitely qualifies. I’ll be pressure cooking rye berries today and inoculating them tomorrow morning with multi spore inoculation.If you are following all proper sterile procedures and still getting contaminated jars, then either the culture is contaminated or the sterilization process for the grains is not effective. Dip your finger in water and soap and work the silicone in a circular motion until the hole is sealed up. You will use some empty jars, tinfoil, hot glue, white air-dry clay (the one that mentains its size when dry) and watercolors. Using minimal spore solution and a self healing Injection port ups the chances of succeeding though. Both achieve the same objective, however the professional one looks better and has a slightly lower risk of contamination as the polyfill air filter can induce ‘Wicking’ where the mycelium can make contact with the air filter and any contaminants that are caught in the filter.
