The difference is the format. The customer receives a bag instead of a box and often handles more of the fruiting setup.<\/p>\n<p style=\"margin:0 0 .8em;font-weight:400;\"><a href=\"\/magic-truffles\/\">Magic truffles<\/a> come from a different process. Truffles are sclerotia, compact masses of mycelium that certain Psilocybe species form inside their substrate. They are grown in sterilised containers over a longer period than a grow kit, then harvested, cleaned, sorted and packed fresh. Because they are a fresh product, they are kept cool after harvest and through shipping. The species in grow kits, Psilocybe cubensis, does not form truffles, so truffles come from other species and cultivated lines.<\/p>\n<style>@media (max-width:700px){.mws-tabel-wrap{overflow:visible!important;border:0!important;border-radius:0!important;}.mws-tabel,.mws-tabel tbody,.mws-tabel tr,.mws-tabel td{display:block!important;width:100%!important;box-sizing:border-box;}.mws-tabel thead{display:none!important;}.mws-tabel tr{margin:0 0 14px;border:1px solid #e4e4e4;border-radius:14px;overflow:hidden;background:#ffffff;}.mws-tabel td{border:0!important;border-bottom:1px solid #eeeeee!important;padding:.6em 1em!important;background:#ffffff!important;}.mws-tabel td:last-child{border-bottom:0!important;}.mws-tabel td:first-child{background:#1f3b33!important;color:#ffffff!important;font-weight:600;}.mws-tabel td:first-child a{color:#ffffff!important;}.mws-tabel td[data-label]:not(:first-child)::before{content:attr(data-label);display:block;font-size:.78em;font-weight:600;letter-spacing:.04em;text-transform:uppercase;color:#2f6b57;margin-bottom:2px;}}<\/style><div class=\"mws-tabel-wrap\" style=\"overflow-x:auto;margin:1.2em 0 1.6em;border:1px solid #e2e8e5;border-radius:18px;\"><table class=\"compare-table mws-tabel\" style=\"width:100%;border-collapse:collapse;font-size:.95em;margin:0;border:0;\"><thead><tr><th style=\"padding:12px 16px;text-align:left;background:#1f3b33;color:#ffffff;font-weight:600;border:0;\">Product<\/th><th style=\"padding:12px 16px;text-align:left;background:#1f3b33;color:#ffffff;font-weight:600;border:0;\">Starting point<\/th><th style=\"padding:12px 16px;text-align:left;background:#1f3b33;color:#ffffff;font-weight:600;border:0;\">Leaves the producer as<\/th><\/tr><\/thead><tbody><tr><td data-label=\"Product\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;font-weight:600;color:#1f3b33;\">Grow kits<\/td><td data-label=\"Starting point\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;\">Sterilised substrate, inoculated<\/td><td data-label=\"Leaves the producer as\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;\">Fully colonised kit, ready to fruit<\/td><\/tr><tr><td data-label=\"Product\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;font-weight:600;color:#1f3b33;\"><a href=\"\/magic-mushroom-grow-bags\/\">Grow bags<\/a><\/td><td data-label=\"Starting point\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;\">Sterilised substrate in a bag, inoculated<\/td><td data-label=\"Leaves the producer as\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;\">Fully colonised bag, ready to fruit<\/td><\/tr><tr><td data-label=\"Product\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;font-weight:600;color:#1f3b33;\"><a href=\"\/magic-truffles\/\">Magic truffles<\/a><\/td><td data-label=\"Starting point\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;\">Sterilised substrate, inoculated with a sclerotia-forming species<\/td><td data-label=\"Leaves the producer as\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#ffffff;\">Fresh, harvested truffles, kept cool<\/td><\/tr><tr><td data-label=\"Product\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;font-weight:600;color:#1f3b33;\">Liquid cultures<\/td><td data-label=\"Starting point\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;\">Selected culture transferred into sterile broth<\/td><td data-label=\"Leaves the producer as\" style=\"padding:12px 16px;vertical-align:top;font-weight:400;border:0;border-top:1px solid #e2e8e5;background:#f6f8f7;\">Living mycelium in a syringe<\/td><\/tr><\/tbody><\/table><\/div>\n<h2 style=\"margin:1.6em 0 .5em;line-height:1.3;padding-left:.55em;border-left:4px solid #2f6b57;\">Why does in-house production matter to a reseller?<\/h2>\n<p style=\"margin:0 0 .8em;font-weight:400;\">In-house production matters because the party that answers your questions is the party that made the product.
