Aloha & Welcome to Hawaii’s Extraordinary Specialty Mushroom Grower

We regret to inform you that our farm tours will be discontinued as of 6/30/2017. We greatly appreciate your support over the years, and we apologize for any inconvenience that this may cause. Our farm will be focusing on providing the highest quality mushrooms to the Hawaiian islands.
Mahalo for your understanding. -Hamakua Mushrooms

Hamakua Mushrooms are a specialty and exotic mushroom, grown in a mixture of corncob, wheat bran and grandis eucalyptus saw dust.  This mixture is called substrate.  Mushrooms are carefully cultivated to grow out of a bottle, a method originally developed in Japan.  This growing method was chosen after traditional hand planting was found to be too time consuming and labor intensive.  Because the process can be automated, “bottle cultivation” allowed for commercial level production. This process allowed Hamakua Mushrooms to develop their signature “Ali’i” mushroom, a 3-½ inch mushroom that has a thick, meaty, one-inch-in-diameter stem.  In keeping with “sustainable farming” methods, Hamakua Mushrooms recycles the substrate and sells to farmers across the island, this rich mixture boosts their crops growth.
