Macro- and micronutrients for Cymbidium seed sowing. Formulation as described by Knudson (1946), modified by Morel (1965) and Fe supplied as chelate of EDTA.
The medium is very minimalistic, especially regarding the microelements. Therefore, it is often enriched with other additives such as coconut water or banana powder.
