I assumed, for some reason, that the foil cap would suffice (i'm a first timer) after ennoculation, I left the 4 open holes on each jar for two weeks before deciding I should seal them. im fortunate the other 5 were forgiving. the moral is USE THE MICROPORE TAPE because bad news bears if you don't, that's why. the jars are not the smooth glass that is shown in the picture. it has grooves and bumps and is very very very hard to see through the glass. I saw first signs of colonization around 6 days. all are at 100 % after about 3 weeks. the mold took over completely overnight and im scared the rest may go as well. ### ⭐⭐⭐⭐⭐ Great little product! *by A***R on Reviewed in the United States on December 5, 2015* Came in decent time and wrapped in plastic wrap, then the jars were wrapped in tin foil, then more plastic wrap, then another layer of Tin foil, haven't inoculated yet but they look good if you need to grow something quickly! Full jars and I've never seen the paper sheets go underneath the jar lid before, makes for an easier inoculation sterility wise. I would buy these again. ### ⭐⭐⭐⭐⭐ These are legit *by D***D on Reviewed in the United States on November 6, 2014* I would recommend these. They are a little pricey, but I already have mycelium after 8 days on about half of my jars. Hopefully the others get going. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/68563927-brown-rice-flour-and-vermiculite-mushroom-substrate-6-jars-1](https://www.desertcart.us/products/68563927-brown-rice-flour-and-vermiculite-mushroom-substrate-6-jars-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
