Use for sowing Spaghnum moss or aquarium sand. Boil the spaghnum moss for 15 minutes in distilled water so that all spores and fungi are killed. When using aquarium sand this is not required. Then fill the spaghnum moss in plastic pots and press it firmly. Alternatively it can be filled with aquarium sand. Then please sow the tiny orchid seeds on top of the spaghnum moss or the aquarium sand. Do not cover with spaghnum or sand.
