White Widow XXL Auto Cannabis Seeds - Type: Autoflower Strain
White Widow Auto by Barneys Farm
A true Amsterdam classic from Barneys Farm, White Widow is now available in an autoflowering variety. The evolution continues of this legendary strain, our White Widow Auto is a sumptuous 70% Indica dominant cross of a Brazilian Sativa X super resinous South Indian Indica, expertly fused with our Barneys Farm Super Auto #1. White Widow Autoflower is an extremely versatile plant. Ideal for all conditions and growing techniques, a mold-resistant strain, resistant to bugs, and copes well even in colder climates so pretty straight forward for all levels of experience.
White Widow Auto 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 80-100cm indoors 100-120cm outdoors and reaches 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 180-250g per plant outdoors and 450-500g /m2 when grown indoors.
All Barneys Farm US orders are processed within 48hrs and discreetly dispatched from our US distribution centre in Illinois.

White Widow XXL Auto FAQs
Is White Widow XXL Auto Indica or Sativa?
White Widow XXL Auto by Barneys Farm is 30% Sativa and 70% Indica.
What is the best way to store my White Widow XXL Auto seeds?
Store White Widow XXL Auto seeds in a cool, dark place in an airtight container, ideally in a refrigerator. Avoid freezing and make sure they are properly labeled and dated.
What is the best temperature for germinating White Widow XXL Auto cannabis seeds?
Germinate at 70°F-90°F (21°C-32°C). Below 70°F can delay or stop germination; above 90°F can cause poor germination and increase the risk of seedlings drying out.
What is the best method to germinate White Widow XXL Auto seeds?
If allowed in your location, we recommend using the paper towel method: place the seeds between damp paper towels, keep them warm and dark, and check daily to ensure the paper towel remains moist.
How deep should I plant sprouted White Widow XXL Auto seeds?
Once germinated, transfer them to soil or similar growth media, making a small hole 5-10 mm deep with a match or pen. Gently place the sprouted seed root-down in the hole. Avoid handling seeds with your hands; use a match or similar tool to position them.
Should I plant my seedlings in their final pots / In the ground outdoors?
No! By carefully transitioning your seedlings from small pots to larger containers, you can ensure your White Widow XXL Auto plants develop strong, healthy roots that support vigorous growth.
Smaller pots dry out more quickly, which is beneficial early in the plant's development. This encourages the roots to spread in search of moisture and nutrients. As the root structure starts to fill the pots, incrementally increasing the pot size continually stimulates new root growth, allowing for ongoing, more precise watering and nutrient uptake.
White Widow XXL Auto cannabis seeds are sold strictly for souvenirs, storage, and genetic preservation.
