Hello Didier Sommer, honestly 40% from 5 seeds is a not so good score, you can\\\\\\\'t compare yourself and the germination test in the laboratory. I\\\\\\\'m sorry you didn\\\\\\\'t have a higher germination rate. Please always check in the product description is there a separate germination rate given.If you please can give exact germination rate, like from 5 seeds 3 have germinated.Seeds germinationAll our seeds are first tested on germination. If the test rate is under 60% these seeds are not sold. Only seeds with a germination rate of over 60% are sold in our online store.We can assure you that all our seeds are fresh - if any of them are unsold during the season, they come back to the breeder, and in the new season, we supply our shop with the fresh seeds.Seeds is a live product, which depends on many important grower skills such as proper planting time, seed depth, type of soil, watering, and light intensity, proper use of fertilizers, weed controls, fungicides, insecticides, soil conditions, and reasonable weather during the growing period. These factors are totally out of the seller\\\\\\\'s control, and germination and growing results are the buyer\\\\\\\'s responsibility and risk.
