How King Agaricus grows up

Previously, The straw was covered on the mushroom to protect compost and mushrooms from rain like squall.

Recently, by taking longer periods to grow the compost and mycelium, King Agaricus has grown from the ground even without straw.

Currently, it takes about four and a half months from growing compost to grow like this.

By being exposed to the sun directly in this way, It is thought to produce more nutrients, such as vitamin D.
