How to grow Double Black
Flowering 55 - 60 days 
Yield 500 g/m² Seb's take
Two phenotypes of the 1998 original Black Domina crossed back into each other, doubling down on a name that already meant business. Yields run to a full kilo per plant outdoors, at a medium potency that asks little fuss for the return.
Where it comes from
G13 Labs crossed two phenotypes of Black Domina back into each other for this one, doubling down, as the name suggests, on a strain that already meant business. The original Black Domina arrived in 1998 as a blend of several Afghani hybrids, and this is pure indica descended straight from it. No outside blood, just more of the same, concentrated.
Nose & flavour
No tasting notes are recorded, but the Black Domina lineage carries the deep, heavy Afghani character it was built on. A hundred per cent indica with a 1998 pedigree behind it, so take the parent at its long-standing word.
The high
Rated at medium potency, which for a pure Afghani-descended indica means a settled, weighty sort of effect rather than a racing one. The record gives no figure to quote, so the make-up tells the story: a plant that sits you down without shouting about it.
Growing it
Flowering in 55 to 60 days and yielding up to a full kilo per plant outdoors, a genuinely heavy return, and one the record says comes without any great difficulty. Indoors she gives around 500 g/m². A hundred per cent indica tends toward the short and sturdy, so expect a manageable frame that carries a good deal of weight for its size.
