Earthworm Castings

PureLife's premium organic earthworm castings work with your soil to promote plant growth and root structure. Both the 5L and 20L bags contain essential plant nutrients and beneficial micro-organisms which increase moisture retention and optimizes growth. The castings can be used both indoor or outdoor for seed germination, seedling propagation, and on existing plants. We recommend creating a mixture that consists of 80%-85% of existing soil and 15%-20% castings.
