This cooker is extremely valuable according to the price range and, in my opinion, the best cooker for mushroom cultivation.

The American brand is ideal for sterilizing and growing your mushroom seeds. You can fit in 10 quart jars in it as it has amazing space up to 23 quarts.

The maximum psi this pot can reach is 15 psi, and this comes with a dial gauge pressure regulator, which gives you an option 5, 10, and 15psi, which you can regulate according to your needs.

Still, you definitely need to supervise your pot constantly as pressure cookers can be difficult to handle.

This pot is very light weight and easy to lift as it is made up of warp resistant aluminum.

The lid is gasket less so you might need to apply a thin layer of Vaseline or wax to further seal the lid metal to metal.

There is just one downfall with the All American pressure cooker: its weight is bulky and large in size, and with substrate filled, the weight of this pot can triple up to its original.

But in conclusion, it cannot get any better than this. With a changeable pressure gauge and amazing quality of cast aluminum, this cooker is made to last for a lifetime, LITERALLY.
