I bought 10 "Jumbo" seeds from Raul. They took 2 weeks to arrive.
I sowed 11 seeds on June 11 (after 15 min in diluted bleach solution). The first seedling popped up around July 16, and I spotted Number #11 coming up on August 27.
Soil is coco coir mixed with spent compost/perlite (previously used for pepper plants). Growing conditions are tropical.
