Seeds germinate al differently at a different moment. This can have detrimental effects on the harvest time. For example, a low yield or varying quality among the crop. With use of the upgrading treatments at Agathos and Atlas, the abnormal seeds are removed from the seed lot, leaving behind a seed lot of better quality.
The latest techniques for upgrading include: X-ray Sorting, Chlorofyl selection and Fluid Density Grading. At this moment, Agathos and Atlas offer Fluid Density grading.
