We present you the Amnesia Fast Version bulk seeds, the fastest flowering photodependent version of the legendary Dutch Amnesia, one of the most cultivated strains of the last 20 years.

The original Amnesia is probably a selection of Super Silver Haze from Greenhouse made by Hy-Pro. Since its presentation, it has managed to win a multitude of awards and cups, being considered since then one of the best Haze hybrids in history.

Its genetic composition, therefore, is the same as the Super Silver Haze, which includes some of the most influential varieties such as Haze, Skunk and Northern Light #5.

Our Amnesia Fast Version is a cross between Amnesia and an autoflowering variety. The first resulting hybrid does not inherit the autoflowering gene, but only reduces the flowering period compared to its Amnesia mother.

How to grow Amnesia Fast Version

Indoors it does not have such a vigorous and sometimes disproportionate growth as Amnesia. But it is still a Sativa hybrid of great development that needs some pruning or branch guidance to reduce its vertical development and promote horizontal development.

From the change of photoperiod to flowering, it is harvested in only 55-60 days. Its buds are large and resinous, as well as very fragrant. This should be taken into account to avoid possible problems.

Outdoors, it is harvested 7 to 10 days earlier than the original, which makes it suitable for areas with short summers where the original Amnesia would have difficulty ripening due to rain. It is usually harvested between late September and early October.

Even so, it is a variety that prefers sunny climates so that it can develop as it pleases. Germinating in early spring, it will not be difficult to obtain plants well over two meters in height.

Characteristics Amnesia Fast Version

The buds are large, dense and very resinous. It keeps the aroma and flavor faithful to that of Amnesia, with hints of citrus, tropical fruits such as mango, wood and pine.

The effects are strong, with a very psychoactive and cerebral onset that will make you forget everything. It is followed by a slow descent with a relaxing finish, a legacy of its NL5 genes.
