How to grow Jack 47
Seb's take
Jack Herer crossed with AK-47, a connoisseur-grade pairing that produces large, trichome-heavy buds and a euphoric, energetic high. Sweet lemon citrus on the nose; the Sativa-dominant genetics tolerate warmer temperatures and heavier feeding, rewarding growers who push her. Stress resistance comes as standard, which is more than can be said for most of us.
Growing Jack 47: what to expect
Feminized photoperiod stock. You control when she flowers, which is a responsibility as much as a convenience; the light schedule guide keeps you on the right side of it.
She takes a conventional 9 weeks to flower. Conventional is underrated; so is knowing what week you're in.
Expect 500 – 600 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.
Listed at 24% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
The aroma is citrus-forward: zest first, everything else in its wake.
The dominant note in the reviews is uplifting; daytime company, by most accounts.
