Sowing instructions
SPRING After harvest, seeds must dry at room temperature for 12 weeks before they can be sown. Sow the seeds at 2mm depth in the 40%Compost+20%Peet+40%Sand and pouwder with 2mm Smoked Vermiculite (0,012g/cm²) between 64-72°F. The container with the seeds is placed in a saucer of water until germination occurs. As a result, the moisture reaches the seeds by capillary action and ensures that the seeds do not dry out. The results are erratic.
