Maintain daytime temperatures of 20–26°C with slightly cooler nights and keep RH between 40–55% during flowering to protect resin and aroma.

Use a bloom-focused feed with reduced nitrogen and increased phosphorus and potassium from week three of flowering, and flush lightly before harvest.

Aim to harvest before late September in most UK locations, scheduling to avoid autumn rains and diminishing daylight.

Yes, low-stress training and topping improve light penetration and yields; remove lower growth that won’t receive light to focus energy on main colas.

It can be vulnerable to bud mould in damp conditions, so ensure good airflow and keep humidity down during the last weeks of flowering.

Yes, if you keep plants compact with topping and train them, but you must manage visibility and moisture carefully on a balcony.

Feminised seeds simplify the process by reducing the chance of male plants, making them a practical choice for less experienced growers.

Dry slowly for 7–10 days in a dark, ventilated space then cure in jars for at least two weeks, checking for any excess moisture.

Some growers succeed by starting early, using compact phenotypes and optimising light and shelter to finish before autumn.

High humidity increases the risk of mould, so follow best practices for high humidity cannabis cultivation: improve airflow, lower ambient RH during flowering, and consider dehumidifiers or timed ventilation.
