Storage of the Biodynamic Preparations
The preparations are the result of a pains taking, time consuming, joy filled process. Each preparation is a special compost in itself. They all work together to strengthen or to moderate and harmonize the various forces working within the living elements (Calcium, Sulfer, Potassium, Phosphorous, etc.) essential to plant growth.
It is of utmost importance that they be stored carefully before use because the living forces in them can dissipate into the environment. Do not store preps in the plastic bags they are shipped in. Use small glass or ceramic containers with glass, ceramic or wood lids - no metal. Plastic lids ok if you keep ajar to allow for breathing.
The compost preparations 502 to 506 (yarrow, chamomile, nettle, oak bark, dandelion), the barrel compost, and preparation 500 (horn manure) should be stored in peat and kept moist. The 507 prep (Valerian) can be kept in the shipping bottle and can be kept in the peat or another dark place.
Preparation 501 is a dry quartz powder. It should be kept in the light in a glass bottle or jar.
Preparation 508, the dried equisetum herb, should be stored in an airy dry place.
Ideally, all preparations should be stored away from electric wires, currents, etc.
A cool dry place in a cellar or out building, root cellar or a prep box buried outside are all good places for storage.
