Greenhouse Seeds in the Netherlands developed the all-Swiss combination known as A.M.S., or Anti-Mold System. The breeders crossed Swiss Fragolina and Swiss Gran Flora to create this strain, which has a slight sativa lean and is resistant to most molds (it’s also the airport code for Amsterdam Schiphol).
Sweet and grapefruit are the most frequently reported aromas of A.M.S. Furthermore, it is said to have an extremely sweet citrus flavor with a sour aftertaste.
Although the breeder lists A.M.S. as slightly sativa, most sources describe it as being primarily indica. However, it produces tall plants with thin leaves, especially when grown outside. The hardy strain is a good choice for beginning growers because it is resistant to most other pests and diseases in addition to mold. A.M.S. typically blooms in late September outside or between 56 and 63 days indoors. In ideal circumstances, it is known to produce extremely high yields. The highest yields appear to be achieved in outdoor gardens.
A.M.S. seeds are offered. Clones might be purchased directly from growers of this strain.
