Double White: Double the Power

The Double White feminized strain from bred by Sweet Seeds is a combination of two powerhouses from the White family; the Amsterdam classic White Widow and Great White Shark – winner of the 1997 High Times Cannabis Cup. The resulting strain is equally impressive with heavy yields of fruity, pungent cannabis.

Growing Double White is a very rewarding process. She grows very easily and isn’t very fussy with nutrients – a high amount of nitrogen in the vegetative stage and high amount of phosphorus and potassium in the flowering stage is recommended to maximise growth, increase bud density and boost yields. Indoors yields are between 450-600 g/m2 of dense, sticky nuggets of terpene-loaded goodness and a similar amount can be achieved outdoors after a medium flowering period of 9 weeks (mid-October for outdoor growers). Here is some further information to help you grow this strain:

  • Medium height – final height is 1 m indoors and up to 1.4 m outdoors.
  • Max EC of water – 1.4 in veg, up to 1.8 in flower.
  • Water pH; 5.8 – 6.0.
  • Recommended lighting: 600 W HPS.
  • Recommended nutrients: Fox Farm FX14049 Big Bloom, Grow Big & Tiger Bloom Trio.

Covered in Sticky, Aromatic Resin

Owing to her 60:40 balance between Indica and Sativa genetics, Double White has only the best attributes from each of her parents including compact, resin-coated flowers with a short internodal distance and a sweet, pungent aroma with hints of pine. Her effect is intense and hard-hitting.
