        Pros:
        • Showed up on time.
        • I received everything I ordered.
        • The quality of the cultures looks.
        Cons:
        • Haven't inoculated yet.
        • I'd love more swag gear.
        I ordered several liquid culture 💉 syringes. The package showed up on time with everything I ordered. It all came in a big zip lock bag with a growing tips cheet sheet, neat Midwest sticker and thank you note. I've processed my own rye berries and sterilized it and my jars. Next will be proccing my substrate. I'll write another review after I've inoculated and given time to grow.
        Thanks Midwest,
        Andrew B.
