Black Widow Strain Origin

The Black Widow marijuana strain is acclaimed to have been developed by Shantibaba. He was once a co-owner of Green House Seeds (GHS). When he left the company to establish Mr. Nice Seeds, the strain was known as White Widow.

Shantibaba took the strain with him and created a new cannabis strain using the original Brazilian sativa and the South Indian indica-dominant hybrid. But, because GHS was still selling their seeds using the name White Widow, Shantibaba renamed his strain Black Widow. He wanted to distinguish his unique cannabis strain from his competitors’.

Since Mr. Nice Seeds has the proprietary genetic properties of Black Widow, the strain is now believed by many breeders as the White Widow strain in seed form. To this end, both avid users and marijuana growers love this cannabis strain.

They’re also the perfect size for growing indoors, as the plant only grows to be about 3 feet tall.
