Goldmine — Heavyweight Seeds

Seb's take

Seb Silverback

Mazar and AK49 combine in Goldmine, an indica-dominant plant that grows into a tidy Christmas-tree shape without any training required. No fuss, no fireworks — just honest, strong resin at 22% THC and a finish inside ten weeks. A dependable strain, and aptly named for a straightforward yield.

Growing Goldmine: 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 10 weeks to flower. Conventional is underrated; so is knowing what week you're in.

Expect roughly 120 cm of plant. Manageable, though she'll appreciate a little training if your headroom is tight.

Expect 500 – 600 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.

Listed at 22% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
