About Double Black
G13 Labs Seeds built Double Black by backcrossing Black Domina 98 onto itself, a stabilization technique meant to lock in the parent's traits rather than introduce anything new. The result is a full, 100 percent indica plant that finishes fast, wrapping up flowering in just seven to eight weeks, among the quicker turnarounds in the indica category. Indoor growers can expect a compact 80 to 120 centimeter plant, well suited to smaller spaces, producing a solid 450 to 550 grams per square meter at a moderate difficulty level. THC lands in a steady 16 to 18 percent range, respectable without chasing the extreme numbers some modern hybrids advertise. Because the genetics are doubled up rather than crossed with anything outside the Black Domina line, growers can expect a uniform, predictable crop from one cycle to the next, which is exactly the point of a backcross like this one.
