About Colombian Jack
Colombian Jack is Kannabia Seeds' sativa-dominant cross, weighted 80 percent sativa to 20 percent indica, and it's built for growers chasing serious potency - THC testing tops out at 29%, among the higher figures a strain like this can post. Difficulty is rated moderate, with flowering wrapping in eight to nine weeks. Indoors, plants stay a manageable 80 to 120 centimeters for 450 to 500 grams per square meter, while outdoor growers can expect taller plants at 150 to 200 centimeters and yields between 500 and 700 grams per plant. That combination of a compact indoor footprint and a much larger outdoor payoff makes this a plant worth considering for anyone with outdoor space, especially given the ceiling on potency the lab numbers suggest it can reach.
