Irish Cream

Start with a mild vegetative feed and increase phosphorus and potassium in early bloom; reduce nitrogen during late flowering to improve resin production.

Maintain strong airflow, keep humidity below 50% during late flowering and remove dense fan leaves to improve ventilation around buds.

It is manageable for growers with basic experience but requires attention to humidity and pruning, so true novices should learn basic pest and mould control first.

Harvest when trichomes are mostly cloudy with some amber for a balanced effect; outdoor crops in the UK generally finish in late September or early October.

A greenhouse extends the season and protects from salt spray, but you must control humidity and temperature to avoid mould and slowed trichome development.

Dry slowly at 18–21°C with 45–55% humidity, then cure in jars at 60–65% relative humidity for several weeks to round out the chocolate notes.

Expect aphids, spider mites and sometimes slugs; regular inspection, biological controls and clean soil practices help prevent infestations.

Yes, greenhouse cannabis cultivation can stabilise temperature and humidity and extend the season, which often improves yields compared with exposed outdoor grows.

Irish Cream responds well to a SCROG to spread light across bud sites, though SOG can work if you prefer many small plants and faster turnover.

Use 10–20 litre pots for single-plant greenhouse cultivation to balance root development and ease of handling.
