Manufacturer Information

With its strong growth, massive resin production and typical White Widow aroma, it has secured a permanent place in cannabis history worldwide. 

It won an award at the High Times Cannabis Cup as early as 1995 – and has been a true classic with recognition value ever since.

Black Widow performs well both indoors and out, with a balanced mix of sativa growth and indica flower structure. It really kicks into trichome production in the second half of flowering, producing frosty buds that are excellent for extractions.
