Original AmnesiaOriginal Amnesia
Classic sativa, staple of Dutch coffee-shops with high yields and a potent, uplifting effect.
Original Amnesia is quite a fast-flowering strain for one that is 70% sativa. Plants are not too big, again, for a sativa-dominant strain, making it eminently suitable for indoors. It's resistant to a wide range of plant pests and mould-related diseases, is easy to grow and also very high-yielding.
Indoors, feeding needs are average and a period of vegetative growth no more than 3 weeks is ideal. In a flowering time of 65 days or so growers can expect yields to be around 600 gr/m2. Outdoors, given plenty of root space, plants can grow to be 350 cm. tall with yields of 1200 gr/plant by mid to late October in the northern hemisphere. Buds are elongated and compact with a good supply of resin.
Scents and flavours are mainly citrus, Haze, incense, cedar wood and spice. THC content is high, at between 15 - 23%, while CBD is very low at 0.01 - 0.2%. The effect is potent, cerebral and uplifting with a special sativa energy. Over time the effect evolves into a more physically relaxing sensation.
