Its reputation also rests on the generosity of its harvests of large flowers covered in sparkling trichomes , and on the potency of its effects. Even today, smokers struggle to find strains as euphoric and physically relaxing as White Widow.

These days, seed banks everywhere offer cheap White Widow imitations. However, at Sensi Seeds, we’re proud to have helped preserve this all-time favorite. Get your White Label regular , feminized , and autoflowering seeds here.
