Germinating the seeds

 

Getting started -   These seeds are small, so work in a well-lit area.

 I recommend starting each seed in separate pots.  You may use small pots (2-3 inch / 5-8 cm) with drainage holes.  Use a well-draining soil mix.  A typical mix is 60% sterilized potting soil and 40% perlite.  An alternate mix is equal parts of coir fiber and perlite, with some slow-release fertilizer mixed in.  Don't add lime to the mix. 

 Fill the pots with the mix and add water until uniformly moist (use bottled water if your tap water is bad).  Place 1-3 seeds on top, then sprinkle a very thin layer (1/8 inch / 3 mm) layer of your soil mix.  Carefully moisten this top layer. 

 Until the seeds sprout, ensure that the top layer always stays moist (but not soggy).  An easy way to maintain high moisture levels is to enclose the pots in a plastic bag or dome.  Leave it open a crack to allow some fresh air to circulate. 

 Keep the pots between 66-77 degrees F (19-25C).  A little cooler at night is ok.  Avoid letting them get above 77F (25C) for prolonged periods.  I recommend placing a minimum/maximum thermometer near the pots, especially if using a heating mat.

 Give the pots bright light but not direct sun.  A fluorescent bulb kept 4 inches (10 cm) away provides the right amount. 

 The seeds should begin sprouting in 2-4 weeks and continue for another 6 weeks.  Increase the air flow a bit and reduce the humidity slightly after they sprout to reduce the risk of stem rot. 

 After they are 1 month old, you may allow the soil surface to dry out between waterings, but keep the lower soil moist.  I recommend waiting until the plants are 2 inches tall (5 cm) before transplanting to a larger pot.  When repotting, avoid letting the soil ball from breaking apart, which can damage the roots.

 Once they have several leaves, you may give them some morning sun.  Transition them to more sun very gradually.  Remember that this is a cloudforest plant and does not like prolonged, strong sun.  Over about 40-50% humidity is best.

Fertilizing -- When they are 1 week old, give a very light dose of liquid fertilizer (about 1/8 strength), and repeat every 2 weeks.  Hydroponic fertilizer is ideal for young seedlings, since it is easily absorbed and complete.   Once they are 3 months old, you may switch to a general-purpose granular fertilizer if you wish.
