What Makes a Black Strain?

Black flower color is largely genetic but partly environmental. Black strains carry the dark, near-black flower of heavily pigmented genetics, and that expression intensifies when night temperatures drop into the low 60s°F during the final two weeks of flower. Not every plant from a black line will color up identically, phenotype variation is normal, but starting from genetics selected for the trait dramatically improves your odds. Bag appeal aside, color has little bearing on potency, so choose on effects and terpenes too.
