Some legends just go on forever - and White Widow is probably one of the most legendary strains of all times. It is very likely every pothead on the globe at least heard of her and now she is available with a new livery - as an autoflowering version for impatient growers. Provides very good yields of a potent product for an autoflowering strain.

White Widow, a name like thundering echo and a timeless legend - there is no stopping her. Each and every stoner on the planet at least heard of the primal mother of the "White" family and nowadays it is a pootle to grow your own, even more when an autoflowering version is available - and even better, this autoflowering version will withstand outdoor cultivation as long as the temperature does not drop below 10°C, so even when reared in less favorable climates you will see a bountiful yield from a healthy plant.

White Widow Auto by Greenhouse Seeds is a legend with a new livery; there is no need to tinker with the lighting schedule - simply let it grow and she will provide you with very good yields of a highly potent end product. Indoors you will be rewarded with 600g/m² after only 7 weeks of flowering - grown outdoors you can expect each centimeter in plant height to translate to roughly one gram of dried bud and at 70-80cm the yield is pretty generous. During the late flowering phase it can become indispensable to support the plant to secure it from toppling over - the buds can grow so fat and highly resinous they bend and in the worst case break the branches.
