    Mike-outgrow- is the man - won’t disappoint

    First, this is the best bang for your buck. Second, the quality is flawless. Third, your order is always delivered on time (often early). But most importantly, there is Mike; the owner of Outgrow, He personally oversees each and every product, as well as, personally answers emails and phone calls. He is a great guy I would not/ will not buy anywhere else. Thanks a million Mike:)

    bRye berry bags.

    This was a very good product, most pre-made bags do not contain enough moisture. or sterilization was poor. My spoors became mycelium quickly, and there has been no sign of any foreign spoor or fungus.. overall very good product. joe sims

    50% success rate last purchase.

    I bought two 1lb bags. Inoculation was done in sterile environment as always. At first glance I thought I had 100% success rate. Upon further inspection after a few days I realized one was growing cobweb mold while the other one had healthy mycelium. Out of the two, only one was successful. But I can never rule out the possibility it was my own personal fault. Although this was the only contam out of the four bags I inoculated that day. Two of them being from my purchase. Two of them being from others. I will not purchase again do to this reason but it does not mean the bags are in fact unsterile. Just my gut feeling. I cannot stress this enough!

    Not happy

    Not happy waste of time...bags didnt even come with rubber stopper. 3 bags of rye were almost fully cooked and rye was smeared allover the bags..
