Wavy Watermelon

Greenhouse cannabis cultivation provides shelter from rain and wind while allowing control over humidity, ventilation and temperature to reduce mould risk.

Switch to a 12/12 light schedule once plants show the desired vegetative size and structure, typically after 4-6 weeks of veg depending on your space.

Use dehumidifiers, circulate air with oscillating fans, prune to improve airflow and avoid watering late in the day to lower canopy humidity.

Coastal soils can be salty and variable; use a balanced nutrient regime, monitor EC, and flush if salts build up, adjusting feed to plant response.

It can work if planted in a sheltered spot or greenhouse to limit salt spray and wind exposure, and if humidity is actively managed.

Dry slowly at 16-20°C with 50-60% RH, avoid too much airflow over buds, and cure in glass jars to preserve volatile terpenes and aromatic notes.

Fungus gnats and powdery mildew are common, as well as occasional aphids; maintain cleanliness and use biological controls where possible.

Harvest when trichomes are mostly cloudy with some amber and after buds have reached peak density, often late September in Down if weather allows.

Yes, but organic growers must be vigilant with cultural controls and use safe organic fungicides and compost teas to manage disease pressure.

Cure for a minimum of two to four weeks, checking jars regularly; longer cures of six to eight weeks often improve smoothness and flavour complexity.
