Willy's Blend is made with official ingredients imported from Brown Treasure in Puerto Rico and produced by Midwest Grow Kits in partnership with Willy Myco. We're the only official producer and vendor in the continental U.S.\"}},{\"@type\":\"Question\",\"name\":\"What is it made of?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Exotic manure aged and naturally leached for at least 2 years, plus six proprietary additives from Willy's formula.\"}},{\"@type\":\"Question\",\"name\":\"Is it pasteurized and ready to use?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Every bag is pasteurized at 160°F for 3–4 hours and hydrated, so you can mix it straight with fully colonized grain spawn.\"}},{\"@type\":\"Question\",\"name\":\"How much spawn do I need?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Plan on 1 to 1.5 grain spawn bags, about 3 quick-colonizing 24 oz jars, or about 6 half-pint jars per 5 lb bag.

To use a code on other items, place the 6-pack in a separate order.\"}},{\"@type\":\"Question\",\"name\":\"Willy's Blend or Black Cow?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Black Cow is our dairy-manure mix with coir and vermiculite.
