Hugh Courtney, A Lifetime Legacy to the Biodynamic Movement

In most human cultures, there is an understanding that with chronological age comes experience, knowledge, and therefore hopefully wisdom. Thus, the label “elder” has the connotation of a person who carries the responsibility andcapacity to lead, guide, and mentor their families, communities, or peoples. In the last several years, the biodynamic community has chosen to honor one of our “elders” at the BDA conference that brings us together from all parts of the continent. This fall in Louisville, we will honor Hugh Courtney.

Does a Void of Course Moon Make a Difference for the Plant Kingdom?

By Hugh J. Courtney

In a biodynamic planting calendar, when the moon exits one constellation and enters another, you will usually see indicated a brief “blackout” period of at least an hour and for some calendars a period of as long as four hours as is the case with the Celestial Planting Calendar published by a Canadian team at What is the reason for this “blackout period?” In the Moon’s journey or transit through each constellation of the zodiac, there comes a point when it makes its last major aspect (see sidebar) with another member of the solar system. Between that moment and the moment that the Moon makes its entrance or ingress into the next constellation, the Moon is said to be “void of course,” which is understood as a situation where the Moon’s influence is nullified in its travels or “Void of Course.”

What may not be realized is that the insertion of blackout periods in a biodynamic calendar is an attempt to take into account the ancient astrological concept of the void of course Moon. However, what is not taken into account by those preparing a calendar is that the exact length of the period of time may vary from one minute to as long as a full day or more. Because of the difficulty of indicating these varying periods of time, it has proven to be more convenient to select a uniform, but arbitrary, length of time to indicate that one should not be working with soil or plants when the Moon exits one constellation and enters another. However, this artifice of convenience can have the effect of reducing the time that one can use to work with plants when the V/C Moon period is relatively brief. On the other hand, by failing to note with exactitude a long period of time when the Moon may be ineffective or ‘void,’ the grower may be working the soil or sowing seed without the full support of the cosmos via the Moon. This could result in introducing less desirable effects into the growing situation.

My personal theory is that a V/C Moon period ultimately will be found to have as negative an impact when working with plants as has been observed when an occultation, eclipse, or nodal point is involved. How might this be determined? One possible way might involve observing germination of particular seeds and subsequent performance of plants which are started both before and during a V/C Moon period.

Anyone interested in contributing to a solution of this problem is invited to use the V/C Moon information in the May and June 2019 calendar pages at the bottom of the article, to see if there is any difference in germination or plant performance for seeds started a few hours before a V/C Moon period versus seeds started well after such a period has commenced but also well before the Moon’s ingress into the next constellation. For ROOT periods, radish seed would be the choice; for FRUIT periods, bean seed might be a good choice; for LEAF periods lettuce seed could work; for FLOWER periods, any flower seed that normally germinates quickly (i.e. marigold) could be used. If the grower should notice any differences in germination percentages, or later on, any differences in growth and crop production so far as seeds planted at the different times, this would be worth noting.

The major aspects as though viewed from the earth are defined as follows:

☌ – conjunction = when two members (generally referred to as planets even when sun and moon might be involved) of the solar system are in the same degree of celestial longitude resulting in an aspect of 0 degrees between the two bodies.

⚹ – sextile = when two planets have an aspect of 60 degrees between them.

□ – square = when two planets have an aspect between them of 90 degrees.

△ – trine = when two members of the solar system relate to each other by an aspect of 120 degrees.

☍ = opposition = when two planetary bodies are directly opposite each other with an aspect of 180 degrees.

There are a number of other aspects taken into account in astrology calculations such as a quintile (72 degrees), or a sesquiquadrate (45degrees), or a semi-sextile (30 degrees), etc., but these minor aspects are not taken into account in determining a void of course Moon situation.

The basic object will be to make a first planting before the V of C period and a second planting during the V of C period. Ideally at approximately the same time of day for both plantings. Pictures of your results would be very much appreciated.

Why Our Subscriptions or Grower Support Plans?

Although we encourage growers to make their own Biodynamic Preparations, we know that this is no small task. The making of Biodynamic Preparations is a labor-intensive, seasonal job, and requires a considerable amount of resources and careful planning. Some of our preparations take more than a year to make! The bulk of our manufacturing and administrative work is completed in the fall and winter months and we try to spend the warm season farming. This approach allows us to keep overhead to a bare minimum and allow customers a very competitive cost for services and saves us from being tied to a desk. This same idea applies to the ‘minimum’ order. If this can’t work for you, contact us and we will try to accommodate you or at least connect you with someone who can better help you.

Grower Support Plans

Annual subscriptions include Biodynamic Preparations, Consultation Services, Educational Materials and Free Shipping. The suggested order, our “Basic Growers Plan”, costs $250 and contains enough materials for thorough treatment of up to 5 acres of land. If you are a compost manufacturer or have any other needs simply contact us for more information.

Horn Silica, BD #501

Virtually from the beginning of biodynamic agriculture, the horn silica preparation, BD #501, has been associated with the forces of sunlight, Or the light ether forces. It has even, perhaps, been seen as a substitute for too little sunlight.


Conversely, when strong sun conditions exist, it has been suggested that one can forego the use of BD #501. (During a visit by Alex Podolinsky in the 1980’s to the American West and Midwest farmlands, several farmers were strongly influenced by this assessment that one was already dealing with too strong sun forces.) In addition, BD #501 is called for during the crop season when the grower is so busy that it is much easier to justify skipping the task of spraying it if one has an authority to fall back on, such as Alex Podolinsky or others.

Rudolf Steiner, in Anthroposophical Spiritual Science and Medical Therapy, refers to the Light ether having derived its name from the fact that most human beings have the ability to see. He further states: “If the majority of humanity were blind, this ether (light) would naturally be given a different name, because other aspects of it would manifest more strongly to the blind.”

Given the geographic forces picture referred to in previous issues (see figure #1) of Applied Biodynamics newsletter, I would like to suggest that we first of all consider the possibility that BD #501 in this western hemisphere may be working more strongly with those “other aspects” of the light ether and secondly, that we be much more dedicated to understanding just how BD #501 should “work” under our North American geographic conditions.

In research, still in progress, Walter Goldstein, at the
Michael Fields Agricultural Institute, in East Troy, Wisconsin, has
seen that BD #501 has not had the harmful effect on crops that has been suggested.
