Hi Daniel, Welcome to the list. Your hab seeds might germinate if you soak them in water overnight, and then sow them in (sterilised?) seedling starting compost if you can get it. If not, just use fine garden topsoil. They should be covered by about 2-3mm of soil and kept moist. A mister is useful for this. While they are germinating you should try to keep them warm - say 30degC. This species typically takes a long time to germinate, but if you can't grow the plants in the Medellín, there's not much hope for the rest of us! If your seeds don't work, send me your address and I'll post some to you. --- Regards, Cameron.
