Perfect for propagation and seed starting, it prevents disease and pests, ensuring healthier plants and faster growth. ## Description Vermiculite is permanent, clean, odorless, non-toxic and sterile. Because it is sterile, “damping-off” is basically eliminated as well as disease, seeds, and insects. It does not deteriorate, rot, or turn moldy. Vermiculite is essentially PH neutral. It promotes faster root growth and quick anchorage for young roots. Soil mixes with vermiculite helps retain air, plant food, moisture, and releases them as needed by the plant. Vermiculite is useful for propagation mixes, seed starting mixes and over seed trays. We offer the size commonly called “medium or horticultural grade” in the greenhouse trade. The granules of vermiculite we sell are approximately the size of dried peas. Review: good service - Arrived in good condition and on time.

The color can possibly depend on the mine from which it is sourced. Perhaps you are confusing vermiculite with perlite? **Q: I'm looking for vermiculite to use as insulation in an outdoor rocket stove to insulate the firebox from outside cooling air, is this product right fo** A: I'm pretty sure you can use this. Other vermiculite products that are labeled for use as 'insulation vermiculite' tend to have a lot of other chemicals put in to them. I'm not sure if 6 quarts will be enough for your rocket stove though. **Q: Do you happen to know the volume (cubic feet) of the 8qt. bag of vermiculite?** A: It's been a while and I cannot specifically be accurate, although picture this. Your common one gallon of milk in the plastic container, two of them stacked one above the other and I believe you come very near to the sizing of one 8 quart zip locked vermiculite. **Q: Is this vermiculite heated(exfoliated)?** A: I had to look that up. :)Yes, this is not raw. It has been expanded/exfoliated. At least according to what I read at duper mining site. ## Customer Reviews ### ⭐⭐⭐⭐⭐ good service *by D***S on November 28, 2024* Arrived in good condition and on time. ### ⭐⭐⭐⭐⭐ BEST VERMICULITE PRODUCT YOU CAN GET AND THE PRICE IS RIGHT !!! *by P***E on November 23, 2012* This is some of the BEST HORTICULTURAL VERMICULITE I HAVE EVER SEEN !!!
