Blue Widow is a remarkably uncomplicated strain that performs well even in less than optimal conditions. Despite cold temperatures, rain, and pests, Blue Widow thrives in the face of adversity, and looks great doing it. While you should always be wary of mould during the late flowering phase, this strain is not one to easily succumb to fungus.

Blue Widow develops sizable green buds with a light purple tinge when grown in colder conditions, giving the strain quite some bag appeal. Adding to this gorgeous appearance is Blue Widow’s insane resin production (gifted to her from White Widow), which can be seen in the late flowering phase when the plant becomes absolutely encrusted with trichomes.

Grown indoors, Blue Widow rarely exceeds a convenient height of 120cm, which equates to a respectable yield of 450g/m² after 8 weeks of bloom. With some pruning, indoor cultivators can push yields even further.

Outdoors, the plant can grow to her full potential. Reaching heights of 200cm or taller, growers have reported yields in excess of 1000g/plant. A relatively early harvest at the start of October means cultivators can grow the strain in moderately warm regions with great success.



With terpene production in full force during bloom, Blue Widow emanates strong scents of citrus blended with wood and pine. When you get around to enjoying the strain, the sweet and fruity notes from Blueberry come to the fore for a rich and pleasant experience on the palate.

Despite being slightly indica-dominant, Blue Widow has a marked cerebral effect that is happy, euphoric, and energising, which she pairs with a deeply relaxing physical effect powered by Blueberry genetics. She is a good social strain that’s fun to share with others. Yet, her carefree effect is also great for some chill solo time at night. Given her medium potency (up to 17% THC), Blue Widow can be enjoyed throughout the day, in moderation, to inspire creativity and positive vibes, without getting lost in the couch.
