http://durgan.org/2016/September%202016/2%20September%202016%20Seedling%20soil/HTML/ 2 September 2016 Seedling soil I produce my own seedling soil for starting seeds and for ongoing growing in some cases. Ingredients are coconut mulch which is superior to the moss now produced, some manure compost, some mushroom discard, some marsh black soil, and some mason sand. Quantities are subjective and in this case are about 200 liters total produced. Compost 160 liters, 20 liters of mason sand, about 30 liters of expanded coconut mulch. The product is stored in the small greenhouse.
