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.
Don Carlos is an indica-dominant variety with dense, resinous buds. It leans toward a calming head-to-body balance that suits evening use.
THC levels typically sit between 18% and 22% in well-grown crops. The potency is clear but manageable for experienced users.
CBD content is low, generally under 1 percent. This makes the cultivar more appealing for THC-focused applications than high-CBD therapy.
Don Carlos descends from Old School Haze x Colombian parentage. The cross gives a resinous, earthy backbone with sharp, spicy highlights.
Seeds are distributed as Feminised to ensure a high proportion of flowering females. This suits growers looking for predictable yields both indoors and outdoors.
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 indoors normally takes 9 to 11 weeks. Outdoors it usually finishes by mid to late October in cooler British conditions.
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.
Plants reach a medium height with sturdy branches and compact internodes. They form heavy colas that support significant resin production.
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.
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.
The immediate effect is a clear uplift that eases into a soothing body relaxation. Users often report improved mood and a gentle focus without heavy sedation.
The smoke carries an earthy base with spicy, peppery notes and a citrus lift on the finish. Terpene expression is richer when plants are grown under stable conditions.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use a loam-based compost with added worm castings, perlite for drainage and well-aged compost to support robust root development.
Increase air circulation, reduce canopy density, use fungicidal teas preventatively and avoid overhead watering in persistently wet conditions.
Begin a modest flush around ten to fourteen days before harvest to reduce excess salts and to encourage cleaner flavours.
Yes. Many growers achieve excellent results using organic cannabis soil growing methods with compost, rock dust and compost teas to feed plants naturally.
Expect around 4 to 5 months from germination to finish outdoors, depending on local microclimate and the onset of autumn rains.
They suit enthusiastic beginners who are prepared to learn humidity control and basic training techniques, but absolute novices may find the damp climate challenging.
Spider mites, aphids and grey mould can be problems; regular inspection and biological controls help keep infestations low.
CO2 can improve yields in a sealed, high-light environment, but it is not essential and adds complexity for small home setups.
Remove lower growth that receives little light and thin the canopy to improve air movement and reduce disease risk.
Start with a balanced base feed in veg, then increase phosphorus and potassium in mid-to-late flowering while keeping nitrogen moderate.
