Yuantide Bio 100% Agar Agar Powder,150g / 5oz, Petri Dish Solidifying Agent, Gel Strength 700g/cm2, for Mycology and Scientific Research

Works well in petri dishes for growing gourmet mushrooms

It's a simple product, but I've had bad Agar before. All you have to do is follow the simple recipe on bottle and your plates will be perfect every time. I use brown rice for grain spawn, so after I do the 2 minute boil on the rice I literally just take the rice water and mix it with the Agar Agar and I get the strongest, healthiest plates I've ever seen. Simple, fast and efficient.

This stuff is as good as the other stuff and it's not cheaper.

Good quality worked great for what we needed it for. It mixed well and poured and set up right. It really did not have a strong smell and was easy to clean up. It helped our budding scientist with his learning what sinks have the most bacteria at school.

Worked perfectly for my petri dishes that I use for mycology. Fungus runs well on it.
