I'm looking for advice based on personal experiences with germinating the three main Brazillian strains, Caupuri, Tucunacá and Ourinhos. I have done a bit of research, and a generalized overview is as follows. Seeds must be fresh, and lose viability fast. Sow seeds with the wing pointed upwards, 1/4 to 1/8 inch deep in rich well draining soil, whats usually reccomended is 25% perlite and sieved potting mix with a bit if course sand. Some recommend a bit of coco coir, and some recommend spaghnum
