100 moments of happiness in a glass tube (forget me nots) The test tube contains our Kop op! growing paper containing at least 100 small happy makers. The seeds of our forget me nots are guaranteed to ensure that you can enjoy this gift for a long time. Place the paper inside in a jar or on the sand outside in the garden. Cover the growing paper with about 2 cm of soil. Give some water every day and the first plants will sprout after about a week. The best time to plant outside is from mid-May to October. Indoors in a jar can be used all year round. Always provide sufficient light, heat and water.
