    • None for me
    MWGK is the best!! I’ve been ordering supplies from Midwest Grow Kits For over three years now and have never been disappointed with their substrate jars and the 5 pound compost bags. I always get great healthy flushes due thier top line supplies. I’ve checked other websites and MWGK has the best prices too by far. Thanks MWGKTeam it shows you love what you do.

    Consistently the best bulk casing I have found

    Rating:
    Pros:
    Cons:
    I have been an amateur mycologist for about 3 years now, and I can honestly say this product is a perfect example of getting what you pay for. I used this product for my first grow, and things went off without a hitch. For my second grow, I wanted to save money so I went with a lesser known company for my casing mix. I found a company that was about half the price, and used them for my 2nd grow. 3 out of 5 containers were contaminated within a week. In this hobby, you have to spend the money to get the results that you are working toward. This is definitely a product that I stand behind.

    This casing is the best I have used. It produces 3 flushes easily. It has the right amount of moisture and it is consistent batch after batch.
