Jack Flash

Jack Flash is a tall, sativa-dominant hybrid that blends the energetic clarity of Jack Herer with the classic robustness of Skunk #1. With a typical THC range of 15–25% and terpene notes dominated by myrcene and caryophyllene, it delivers a fruity, slightly skunky aroma with an underlying herbal spice. This variety is known for an uplifting, energetic head high that suits daytime use, creative activities, and social situations rather than heavy sedation. For growers Jack Flash is approachable: rated easy to cultivate, it thrives outdoors in sunny, Mediterranean-like climates and rewards with high yields. Flowering runs long compared with many sativas — expect roughly 10–14 weeks — and plants tend to stretch tall, so plan vertical space. Because it reliably produces large, resinous flowers and has shown up in Cannabis Cups, it’s a good choice for gardeners seeking strong performance without advanced techniques.
