Discover the secret to successful mushroom cultivation with freshly-made Malt Extract Agar plates! Crafted with a perfectly balanced blend of organic ingredients including agar, malt extract, locust bean gum, and yeast extract. Unlike other pre-poured plates that can sit for weeks before shipping, our plates are made fresh daily to ensure maximum potency and efficacy. Each set of 5 plates is carefully sealed in polyolefin packaging for optimal freshness. Experience the difference of truly fresh agar plates - order you

We are excited to announce starting in April 2023 all our agar plates are now machine poured in our new clean room. We measure out the ingredients and add them to the MediaPrep machine and it blends and mixes, then sterilizes it for 30 minutes at 18 PSI and cools it to 145 degrees. Then it is pumped over to the dispensing machine that measures out 25ml per plate. The MediaFill shakes each plate as it passes a UV-C light. Each plate is capped and then labeled by the laserjet printer. This machine will ensure every plate has the exact same level of agar and much less room for any human error. 

Our 5 Sterilized Malt Extract Agar Plates are the perfect choice for healthy mycelium colonies. Here's what makes them stand out:

  • Each batch is made with a carefully crafted blend of ingredients to promote optimal growth.
  • Our plates are crafted from durable 100mm polystyrene Petri dishes.
  • To ensure purity, every plate is pressure sterilized and poured in our lab under the protection of a laminar flow hood.
  • For best results, we recommend storing our plates in the refrigerator and using them within 4 weeks of delivery.
  • Our plates come in assorted colors, which not only look neat but also helps us keep track of dates for optimal use.

    What is Agar? How do I use it?

    Agar is a versatile tool used by mushroom growing enthusiasts to cultivate high-quality mycelium colonies. By squirting a tiny amount of spore solution onto an agar plate and incubating for a few days, white mycelium patches will begin to form, allowing you to select the fastest-growing and most robust mycelium for use in your growing project. With agar, you can isolate any mold without compromising your culture plate, a technique used by experts to grow the biggest and best mushrooms showcased on various forums.

    Once you've chosen your mycelium colony, you can create a still air box or use a flow hood to cut a piece of the agar and transfer it into a spawn bag, jar, or liquid culture to grow. Whether you're a seasoned professional or a beginner, agar is an essential tool to achieve success in mushroom cultivation.

      Cons:
      First time using these and they worked as expected. A couple of the plates seemed to have melted and spilled but were salvageable.

      Definitely recommend

      Cons:
      The reviews are true. Midwest Grow Kits have great customer service. I had a contaminated agar plate. I am usually the type of person that just leaves it be, but seeing reviews about how helpful and responsive they are, I decided to reach out not really knowing what to expect. And in less in 24 hours they got back to me and sent me a replacement. Greatly appreciated. The other dishes were good. Using it to test my liquid cultures (also gotten from them).
