Black Widow genetics are a combination of White Widow and Misty and is a mostly indica strain.
Plants have a moderate amount of leaves and maximum quantity of buds of extreme hardness, which are valued a lot by the commercial growers. Outdoors it can grow up to 150 - 200 cm. in height. Indoors it barely reaches 100 cm. It doesn't tolerate high humidity during late blooming as it is somewhat susceptible to mould. Yield is 400 gr/m2indoors and 300 gr/plant outdoors.
Black Widow is an effective medical strain with sedative and relaxing properties originating from its high CBD content. It has floral aroma with menthol aftertaste.
