Use 18/6 for veg and switch to 12/12 for flowering; ensure consistent dark periods to avoid stress and hermaphroditism.

Adjust distance by light intensity: start at 45–60 cm for high-output LEDs and move closer as plants stretch, watching for light burn on upper leaves.

Match PAR output to plant stage, run a consistent photoperiod, use full-spectrum LEDs for flower, keep canopy even with topping or LST and control heat to maintain 20–26°C during lights-on.

Start with a balanced vegetative feed then increase phosphorus and potassium in bloom; reduce nitrogen in late flowering to encourage ripening.

Ensure good air circulation, avoid dense canopies, site plants where they dry quickly after rain and harvest early if persistent wet weather threatens trichomes.

Watch trichome colour: a mix of cloudy with some amber gives a balanced effect; pistil darkening and swollen calyxes also indicate readiness.

Topping, LST and SCROG work well to even the canopy and boost yields, with attention to supporting heavier colas late in flower.

Dry slowly for 7–12 days in a controlled 50–60% RH environment, then cure in jars for at least 2–4 weeks to develop flavour and smoothness.

Aphids, spider mites and powdery mildew appear in UK grows; regular inspection and early biological or cultural controls are essential.

Cultivation remains illegal for recreational use without a licence in the UK; always check current laws and obtain appropriate permissions for medical or research growing.
