Ceiba pentandra - Seeds and Germination

Ceiba pentandra seeds have a waterproof skin which makes the germination slow, from months to few years. We can broke it by different treatments which we have to do before sowing the seeds.

Previous treatments
Put the seeds in boiled water and move it away from the heat source. Let the seeds in that  water for 24 hours.
The ideal substrate is a mixture of sand and black  peat in equal parts. 
Mix and water it well. Drain the mixture, pressing to expel all the water.
The soil has to be wet but no waterlogged.
Fill with the soil the container chosen to sow the seeds.

Put the seeds on the substrate, leaving two cm between them.
Cover with a layer of soil equal to the thickness of the seed.

The seeds may take 1-4 weeks to germinate under perfect conditions.
For all that time we have to keep constant moisture and temperature.
In order to improve germination, the temperature should be around 20ºC.
