What is Vermiculite?

Vermiculite is a natural mineral that expands when heated. It is typically found in deposits that were formed by the alteration of certain types of mica minerals over time. Vermiculite is lightweight and has excellent insulation properties, making it useful in a variety of applications.

When vermiculite is heated, it expands into a spongy material that is fire-resistant and has excellent thermal and acoustic insulation properties. Because of these properties, vermiculite is commonly used in construction and insulation applications, as well as in horticulture for soil conditioning and as a medium for growing plants. It is also used in the manufacture of various products such as brake linings, fireproof coatings, and packing materials.

Far better to deal with than Mycology Supply. The pellets were great! Made a great substrate for my Son’s shiitake when mixed with some wheat bran.

A few speed bumps but great customer service.

I ordered a grow bag bundle but was disappointed when I saw that one of the two bags was defective and came with a hole in it. I reached out to the company and they assured me it was an unusual occurrence and sent me TWO new bags as a replacement. Very happy with how they responded and fixed the situation.
