Our take
Black Diamond is a feminized, indica-dominant cross of Blackberry and Diamond OG that brings earthy, woody, berry-forward flavor together with 16% THC and a calm, contented effect profile. It suits growers who have a few grows under their belt — intermediate-level experience will help you get the most from its dense, resinous buds.

Growing notes
Black Diamond is rated intermediate, so first-time growers may want one harvest of experience first. Indoors, expect flowering to wrap up in 56–70 days, giving you some scheduling flexibility. Outdoors it finishes around mid-October. Plants stay at medium height, which keeps canopy management straightforward. The terpene mix of myrcene, pinene, and caryophyllene tends to produce a noticeably fragrant grow space.
