A true Amsterdam classic from Barneys Farm, White Widow is now available in an autoflowering variety.

White Widow Autoflower is an extremely versatile plant. Ideal for all conditions and growing techniques, a mould-resistant strain, resistant to bugs, and copes well even in colder climates, so pretty straightforward for all levels of experience.
White Widow Autoflower is a classic Indica shape, extra compact compared to the feminised version but still a vigorous, fast grower, becoming bushy and wide in time for flowering. Growing to heights of 80-100 cm indoors and 100-120 cm outdoors and reaching maturity in a rapid 70-75 days from seed. With the onset of flowering, large Sativa-like, heavy, and super-sticky solid buds burst from its branches, the extraordinary resin production creating a thick blanket of glistening trichomes covering its colas, almost white in appearance, frosting the long bright orange pistil and small dark green sugar leaves. This Amsterdam classic comes with an exotic terpene profile packed full of pungent, skunky, sweet citrus aromas and earthy, pine wood, and spice flavours. Expect 180-250 g per plant outdoors and 450-500 g/m² when grown indoors.
