The Humboldt Mix Preparation

The Humboldt Earth mix is formulated so that containers can be filled dry and then watered after seeding or transplanting.  The Humboldt Earth wets easily and uniformly, eliminating the need for pre-wetting.  As with any soil mix, over wetting will negatively affect the physical properties of the mix.  Never compress any mix too tightly when planting.  The Humboldt Earth is not pasteurized and should not be sterilized or pasteurized.
