For all you local growers, Menehune Magic! Our own local soil and compost recycler on Oahu. One can find bags of menehune magic in some stores but the best is to get out to Campbell industrial and get a truck load of your own custom mix made right there. The cost is by far the best in the islands if you are a soil user(check their pricing list online). I will suggest conditioning any mix before use, Menehune Magic ages their compost 12 months before mixing(minimum industry standard). I personally would plan ahead and age after mix for another 60 days before use. Look them up!
