About Don Carlos

Don Carlos is an indica-dominant cultivar bred from Old School Haze x Colombian that produces dense, resin-coated flowers. It favours experienced organic growers who can manage humidity and airflow, and it rewards careful soil building and canopy control with robust yields and pronounced flavours.

Grow Difficulty:

Growing Don Carlos in a wet Welsh valley climate increases the risk of mould and requires strict canopy control. The overall difficulty is intermediate because it needs close attention to airflow and humidity management.

Flowering Time:

Flowering indoors normally takes 9 to 11 weeks. Outdoors it usually finishes by mid to late October in cooler British conditions.

Yield:

Yields are medium to high when plants receive consistent light, nutrition and air flow. In damp seasons output can drop if fungal issues are not prevented.

Height:

Plants reach a medium height with sturdy branches and compact internodes. They form heavy colas that support significant resin production.

Environment:

Indoors Don Carlos responds well to SCROG and low-stress training, and height can be controlled in a small Northamptonshire grow room. Outdoors in Northamptonshire the plants do best in a sheltered, south-facing spot to reduce moisture exposure.

Climate:

Growing Don Carlos in Northamptonshire requires active measures to counter the wet Welsh valley climate, such as raised beds and good drainage. Site choice and timing in Northamptonshire will strongly affect bud quality and disease pressure.
