In some parts it’s very difficult to find vermiculite, especially in the winter. Vermiculite is a very good tool for growing mushrooms.
 It can be used as part of your substrate, or as part/ or only ingredient in your casing mixture.

 This brand of vermiculite has been used with great success un-sterilized, with very low to no contamination. Very high quality and clean. Good way to condition your vermiculite for un-sterilized use is to soak it with H2O2(hydrogen peroxide) and add some horticultural lime. Then squeeze the excess water out and lay it on top of your substrate or casing to help retain necessary moisture and to help initiate pinning. Check out our pre-sterilized pH balanced casing soils for better results with casings. A mixture of vermiculite and perlite make the best bottom layer for casings, and for cakes. One gallon of vermiculite goes a long way, but 4 gallons is best for covering bottom layers.

Great price...It's hard to find a place that carries verm (perlite as well) where I live & when you do it's higher priced than this & soon out of stock. When I order fro ET I have them include a bag of this and perlite as add ons, it's a great price & saves me gas & an extra trip for them later when I'm out. ET is the best! :) Written by Dale on Thu 5 Jan 2017 6:23:02 PM GMT
Perfect sizeI use this for PF Tek jars with BRF. It's the perfect size and I get fast colonization. Just another one of ET's fine products. Spore syringes are the best out there too. Written by Mark on Thu 5 Mar 2015 8:13:05 PM GMT
