Black Widow Automatic

 8.00 499.00

The Black Widow automatic is a good combo of two newer marijuana strains: the White Widow feminized and Pure Power Plant feminized. These strains are from different genetics, Sativa and Indica, making the Black Widow automatic an evenly balanced hybrid.



The Black Widow automatic is bright green with purple and white accents. The smell and taste are fruity with an undertone of Skunk. She will leave you deeply stoned. The Black Widow automatic does best indoors because she might give you smaller yields when exposed to rainfall. For those who are new to growing, this is an easy plant; yields might be less for amateur growers.

The Black Widow automatic is 40% Indica, 40% Sativa and 20% Ruderalis. She contains 15% of THC and has a low CBD-level. The indoor yield should be around 350-400 grams per square meter, and its height will be about 50-90 cm. The outdoor yield should be about 175-210 grams per plant, and its height will be around 70-120 cm. The growing period should take about 4-5 weeks, the flowering period 6-7 weeks. Harvest should be planned 10-11 weeks after planting the seeds.
