About Marathon Og
Marathon Og is an indica-dominant hybrid bred from Marathon and OG Kush to deliver strong THC effects with a stable growth pattern. It performs particularly well indoors, where controlled environments in Durham or similar climates can maximise yields and bud quality while reducing late-season risks.
Grow Difficulty:
Growing Marathon Og is best suited to growers with some experience because it benefits from careful feeding and training. It copes reasonably well with cool northern summers but benefits from indoor environments to avoid late-season weather issues.
Flowering Time:
Flowering usually completes in 8 to 10 weeks under ideal conditions. Expect dense buds that respond well to an indoor light cycle.
Yield:
Yields are medium to high when grown indoors with proper training, often between 400 and 550 g/m². Outdoor yields are more variable and depend on the season length.
Height:
Plants grow to a medium height indoors, typically 80–120 cm with topping and low-stress training. Outdoors they can stretch taller if given room and nutrients.
Environment:
Indoors Marathon Og thrives under controlled conditions, making it well suited to compact grow spaces in Durham. Outdoors it can do well in a sheltered garden but in Durham growers should watch for autumn chills and mould risk.
Climate:
In Durham the strain performs best when started indoors or given season-extension outdoors due to cool northern summers. Provide shelter, good airflow and a late-season drying plan to avoid rot in Durham's damp conditions.
