About J1

A cross of Jack Herer and Skunk 1, J1 leans into the genetics of two classic lines without settling fully into either extreme. Growers rate it a moderate challenge, and indoors the plant tends to stay at a medium height, making it manageable in a tent or closet setup. The terpene profile is unusually broad for a hybrid, led by myrcene, limonene, caryophyllene, and humulene, with smaller contributions from terpinolene, pinene, and linalool rounding out the aroma. That kind of spread often reads as a busy, layered nose rather than one dominant note. THC testing has come in close to 21 percent, putting it solidly in the mid-to-upper range for a hybrid of this type. There isn't much documented yet about how J1 affects mood or body, or what flavors show up in the smoke, so judging those aspects will come down to trying a cut for yourself.
