About Critical Jack Autoflowering
Critical Jack Autoflowering combines Critical+, Jack Herer, and ruderalis genetics, and this cut from Dinafem Seeds carries a 40 percent indica, 60 percent sativa split while testing strong, up to around 23 percent THC. It flowers in 9 to 10 weeks at a moderate difficulty level, reaching 70 to 110 centimeters indoors for a yield of 400 to 500 grams per square meter, while outdoor plants grow slightly taller at 80 to 120 centimeters but yield a more modest 60 to 200 grams per plant. That gap between the strong indoor yield and the more limited outdoor figure is fairly typical of compact autoflowering genetics, which trade the extended vegetative growth of photoperiod outdoor plants for a faster, more predictable cycle. Combining two parents in Critical+ and Jack Herer with ruderalis for the autoflowering trait, this one is built for growers who want strong potency without stretching the calendar out.
