Grotzke draws on more than 40 years of experience to
provide the reader with a comprehensive perspective
as well as practical tips on soil blends, biodynamic
preparations, water, light, sanitation and cuttings.
All too often, greenhouse management means a reliance
on the synthetic plant foods of hydroponics or the heavy
chemical use of container plant growers. This small
guide — based on biodynamic methodologies — shows that
there is another, more natural way.
