Use a well-ventilated greenhouse with passive and active airflow, a dehumidifier for flowering, and modest supplemental lighting to extend usable hours in late season.

Aim for 40–50% RH during late flowering, increase airflow around colas, and remove dense fan leaves to improve evaporation and reduce mould risk.

Feed a balanced NPK mix in veg, taper nitrogen in flowering while increasing phosphorus and potassium, and monitor EC to avoid nutrient burn.

Harvest when most trichomes are milky with some ambers depending on desired effect, typically around nine weeks, and cut in the morning after drier conditions when possible.

Dry slowly to 55–60% humidity, then cure in jars at 60–65% RH for several weeks with daily burps initially to develop flavour and smoothness.

It is not a mould-proof variety and needs active prevention in moist areas through airflow, hygiene and biological predator use for common pests.

Yes, Feminised seeds reduce the need to sex plants and are recommended for growers who want predictable female crops and simpler greenhouse management.

Low-stress training and topping early, followed by SCROG or selective defoliation, give even light distribution and improve yields.

Expect around 12–16 weeks from seed to harvest for Feminised photoperiod plants under typical schedules, varying with veg time and greenhouse conditions.

For UK greenhouse cannabis growing, emphasise ventilation, moisture control and flexible feed schedules to handle variable weather and protect dense buds from rot.
