    What is Agar? How do I use it?

    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. Working with agar seems intimidating and prone to contamination but with the chloramphenicol added, the risks are much lower and easier than you can imagine!

      I made an error with inputting my address and the team was so helpful every step of the way with getting that issue rectified even though weeks had passed since the delivery estimate. Anyway, once that was solved, my order was shipped out and I have had no issues whatsoever with my product. I love the great customer service that accompanies their reliable products.
