About Secret Weapon
Secret Weapon blends Northern Lights x Haze to give growers a reliable hybrid with clear, focused highs and robust growth. Grown in London greenhouse conditions it rewards careful humidity and airflow management, producing dense, citrus-pine buds across an eight to ten week flowering window.
Grow Difficulty:
Under a moist western coastal climate the strain needs careful humidity control to prevent mould and bud rot. It is intermediate in difficulty and rewards growers who manage ventilation and leaf density.
Flowering Time:
Flowering normally finishes in eight to ten weeks under stable conditions. Cooler temperatures at the tail end of flowering can push plants toward the longer end of that range.
Yield:
Yield is medium to high when canopy management and mould prevention are applied consistently. Greenhouse crops that avoid damp pockets produce dense, resinous buds.
Height:
Plants reach a moderate height with strong branching that supports heavy colas. In greenhouse conditions they often hit one to two metres without aggressive training.
Environment:
In London this variety thrives in a greenhouse where you can control humidity and airflow, and it also performs well in well-managed indoor rooms. London growers should prioritise ventilation and keep an eye on damp spells.
Climate:
Growing Secret Weapon in London demands attention to the moist western coastal climate and its frequent humidity spikes. Using a greenhouse with good airflow and a dehumidifier will cut mould risk and improve bud quality.
