Greenhouse Seeds AMS have genetics of both Swiss sativa and Swiss indica - a win win situation! Our respected sources have confirmed the effects of AMS cannabis seeds are very strong highs with a clear side and a more introspective one. AMS has a very particular taste, which some say is sweet and fairly complexed - so enjoy! As a grower, you can expect flowering periods of 9 weeks to deliver the most amount of resin - huge quantities in fact! For those commercial growers amongst you, expect a harvest in 8 weeks and yields of between 500 and 700 gr/sqm - result! If you brave it and grow outdoors then expect to harvest at the start of October?obviously depending on the great weather.
