I got Thaumatococcus daniellii seeds from Cameroon (fermamo2002). I was expecting them to need at least a few months to germinate, but the fastest so far popped up after only 9 days.
I cleaned the seeds with dilute bleach (30 min soak) and then soaked them in water for 3 days. Seeds were then placed in peat moss. The picture below is from a batch of 15 seeds sown on Jan 5 and photo was taken on Jan 14.

The first batch, however, was sown on Jan 1. I wasn't following the germination closely, and on Jan 12 I noticed several seeds had sprouted. On Jan 14, 7/10 had sprouted. I also transplanted one germinated seed to a bigger container. Some snapshots:

I live in the lowland tropics. We're currently in the dry season (winter). I use plastic containers for germination and place them in a rack at the N side of the house. I added a screenshot of the weather we've had lately: 20-22ºC min, 33-34ºC max.

I prefer to resurrect an old thread rather than start a new one (easier to find information with the search engine afterwards).
