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 10 sterilized Black MEA Agar plates are the perfect choice for healthy mycelium colonies. Here's what makes them stand out:

  • Each plate is made with a carefully crafted blend of ingredients to promote optimal growth.
  • Our plates are crafted from durable 100mm polystyrene Petri dishes.
  • 100% Pure lab grade carbon added
  • 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 3-4 weeks of delivery.

      What is Black Agar? How do I use it?


      Black agar is a type of nutrient agar that contains activated charcoal or carbon black, which gives it a dark color. It is a popular medium used in mycology for the cultivation and isolation of different types of fungi.

      Agar plates have been used for decades by mushroom growing enthusiasts and are becoming more popular again. You start by squirting a tiny amount of spore solution on the plate. Incubate for a few days and white mycelium patches begin to form. Agar lets you choose the fastest growing and most robust mycelium for use in your growing project while being able to isolate any mold without ruining your culture plate.

      Isolating a culture is how the experts grow the biggest and best mushrooms, the ones you see in pictures on the many forums. After you choose your mycelium colony to use, create a still air box or use a flow hood and cut a piece of the agar out and place into a spawn bag, spawn jar or liquid culture to grow.

      When properly used, black agar provides an ideal substrate for the growth of fungi and allows for the observation and characterization of the colony morphology and pigmentation of the fungus being studied. The dark color of the agar provides a good contrast to the white or light-colored mycelium, making it easier to observe the growth and morphology of the fungus. The carbon in the agar can also promote the growth of certain types of fungi while inhibiting the growth of bacteria, which can help to prevent contamination and promote the growth of pure fungal cultures.

      Overall, black agar is a valuable tool in mycology for the cultivation and study of fungi, and its proper use can lead to accurate and reliable observations and results in fungal research.

        Don't be afraid of the green color on your mycelium, I believe it's consuming the green dye in the agar. :)
