About Cuban Black Haze

Cuban Black Haze is a sativa-dominant hybrid bred from Cuban Black x Haze that delivers a bright cerebral high with a subtle physical ease. It suits growers who can manage humidity and train lanky plants; in greenhouse runs it rewards attention with dense, terpene-rich buds and a complex flavour profile.

Grow Difficulty:

Cultivating Cuban Black Haze in humid greenhouse environments demands vigilant mould prevention and strong airflow. The plant is moderately forgiving but rewards growers who prune and train actively.

Flowering Time:

Flowering normally completes in nine to eleven weeks under stable conditions. Some phenotypes can finish close to nine weeks with optimal feeding and light.

Yield:

Yield is moderate to generous when plants are trained and fed correctly. Greenhouse runs in Suffolk often produce denser buds with careful humidity control.

Height:

Plants reach medium to tall heights with elongated internodes typical of haze varieties. They respond well to topping and screen-of-green to manage vertical stretch.

Environment:

Indoors it adapts to small spaces when trained to limit vertical growth in Suffolk. Outdoors it performs best in sheltered spots or inside a greenhouse where humidity can be managed.

Climate:

Growing Cuban Black Haze in Suffolk within humid greenhouse environments encourages richer terpene development. Growers must control humidity and airflow constantly to prevent botrytis and mould.
