About Jack Herer Fast
Seedsman built a quicker-finishing version of the famous Haze and Northern Lights #5 and Shiva Skunk cross, and the name says it all - this sativa cuts flowering time down to just 7 to 8 weeks, noticeably faster than the classic original. The genetic split runs 45 percent indica to 55 percent sativa, and despite the shortened timeline, potency doesn't suffer: THC still reaches 21 to 22 percent. It's rated a moderate difficulty grow, reaching 90 to 140 centimeters indoors and producing a strong 450 to 550 grams per square meter, numbers that hold up well against the standard, slower-flowering version of the same lineage. For growers who love the pedigree but don't want to commit to a longer flowering window, this faster cut delivers comparable strength and yield without asking for the extra weeks of patience.
