Germinating the seeds
When to plant -- Plant your seeds when you receive them for best germination. Getting started -- You may plant each seed in individual, small containers. Or you plant them all in a single container, but it may be more difficult to transplant them later. Either way, use pots with drainage holes. For soil, use a well draining mix high in organic matter. A typical mix is 2 parts potting soil to 1 part
perlite Gently place a seed in each
pot (or if using a communal pot, space them about 1 inch (2.5 cm) from each
other). Then sprinkle a thin layer of
long-fibered sphagnum moss (not ground peat moss). This helps retain
moisture around the seeds while allowing light to reach them, which aids
germination.

shows how much moss to use. If you don't have sphagnum moss, sprinkle a
bit of your soil mix around the surface. Add water until the soil is evenly moist, but not soggy. Until the seeds sprout, ensure that the soil surface never dries out. An easy way to maintain high humidity by enclosing the pots in a plastic container or bag. Leave it open a crack to let in fresh air. Once or twice a day, you may need to drip a few drops of water on the surface to keep it moist. The ideal temperature for germination is between 65 and 77 degrees F (18-25°C). A little cooler at night is ok. Avoid letting them get above 80° F (27°C) for long periods. I recommend placing a minimum/maximum thermometer near the pots. A fluorescent or LED bulb kept 4 inches (10 cm) away provides the right amount of
light. Protect from direct sun. Growing onward... Fertilizing -- Feed weekly with a very dilute (1/8 strength) liquid fertilizer. Hydroponic fertilizer is ideal for seedlings, because it is easily absorbed and contains all essential nutrients. After 6-8 weeks, you may switch to a granular fertilizer that contains micronutrients, following the dosage on the package. Or continue feeding weekly with liquid fertilizer at 1/8 strength. Transplanting -- When your plants are 2-3 months old, you may gently
transfer them to a larger pot. Water the soil first, and avoid letting the
soil ball break apart, which can damage the roots. After transplanting,
give no sun or liquid fertilizer the first week. Above about
40-50% humidity is best. If your plants seem to suffer from low humidity
indoors, consider using an ultrasonic room humidifier, sold at
home improvement stores and thrift shops. - Jeff Strange Wonderful Things
