6Pcs Wide Mouth Mushroom Liquid Culture Lid Grain Spawn Cultivation Mason Jar Lid with 0.2 micron PTFE Syringe Filter & 20mm Self Healing Injection Ports For Mushroom Growing Mycology(Golden)

Product Information

This is because the grains are high in nutrition and vulnerable to a whole host of potential competitors that can easily outgrow mushrooms, such as trichoderma molds, cobweb molds and other project-ruining contaminants. Again I didn't make pictures for this step, my hands were full but check out the whole creation process in the video.

You’ll see that the top has more perforations/vents which will indicate which way up the filter should be.

Available from 5 gram - 50 gram these jars are lightweight and compact for easy travel use, they are also reusable and refillable. Its versatile design makes this the perfect plastic container for creams, powders, balms, glitter and gels.

If using a pressure cooker or canner with smaller glass jars, adjust the amount of grain/wood accordingly. I cleaned the area and heated the needled up to glowing using a little handheld blowtorch lighter kind of thing used for cooking. Or, if transferring grain spawn from another jar or bag, use a sterile long-handled spoon to place 3-4 scoops of grain spawn into your sterile substrate. We’ve been working for over 15 years to find the perfect mushroom growing substrate formula, and we have finally found it! This is all for OCD to be honest, the only benefit from using a more tidy air exchange is less chance of contamination from ‘Wicking’ off the fibre fill, but if you’re careful you won’t get that anyway, you can get similar results from micropore tape and silicone.If you use a punch, make sure it is supported on the underside of your work surface to not bend or dent the metal. I have syringes I’ve made myself from prints so I can control how much spores I use and control proper sterile techniques. div%3E%3Cdiv%20class%3D%22title_and_year%22%3E%3Cspan%20class%3D%22title_and_year_title%22%3ELidded%20Mushroom%20Jar%3C/span%3E%3C/div%3E%3Cdiv%20class%3D%22medium%22%3EPorcelain%3C/div%3E%3Cdiv%20class%3D%22dimensions%22%3E11.
