Seb's take

Seb Silverback

Green Crack crossed with its own autoflowering version to produce the first fast-flowering line of the name — efficient, if not modest about it. Smelly, sticky, ash-green buds arrive in a record forty-four to fifty days indoors. A branchy Sativa-leaning structure that rewards both novice and seasoned growers with genuinely large yields.

Growing Fast Flowering Green Crack: 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.

Flowering is done in roughly 7 weeks. The calendar will suit the impatient; the flowering notes will suit everyone.

At around 250 cm, headroom is the whole conversation. Measure your tent, then measure it again — the light planner will keep the light off her canopy.

She crops generously — 600 g/m² in capable hands. Capable hands read the feeding guide; generous crops tend to follow.

Listed at 18% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
