Auto Black JH: The Perfectly Balanced Auto

Produced by Original Sensible Seeds, Auto Black JH is a feminized autoflower that combines the qualities of Sativa-dominant Jack Herrer with Black Domina, an Indica-leaning hybrid. These are then crossed with a Ruderalis variety to produce this mighty autoflower which can deliver in record times.

Ideal for Medicinal Cannabis Extraction

This autoflowering variety is the perfect strain for a variety of cultivators; those crunched for time or space, impatient for a heavy harvest and simply enjoyers of top-quality bud. Auto Black JH is able to deliver indoor yields of a potential 450 g/m2 in a record time of under 9 weeks from seed to harvest. This makes her one of the fastest strains available in the cannabis community at the moment! She also reports relatively high CBD levels, and this paired with her highly resinous buds make her an ideal candidate for medicinal cannabis extracts.
