White Widow XXL Auto is a feminised seed strain that is the result of a selection of White Widow plants (Brazilian x South Indian) based on their size and yield which were then crossed with the auto breeding plant BF Super Auto #1. This mostly indica (70%) strain grows well indoors as well as outdoors in a range of climate types.

The complete life-cycle of this strain is done in 70 - 75 days. Plants grown indoors will reach a height of approximately 80 - 90 cm. while those cultivated in an outdoor setting will become a bit taller at 100 - 120 cm. Yields indoors are about 500 gr/m² while outdoors a single plant can produce as much as 1200 gr. The buds are compact and have a distinctly white appearance due to the amount of resin.
