About Mars Og

Mars Og is an indica-dominant hybrid bred for resin and aroma, showing robust growth and reliable bud formation. In the Scottish Highlands it needs careful site selection and proactive mould prevention due to the cool Scottish outdoor climate, but it rewards growers with potent, flavourful harvests when managed correctly.

Grow Difficulty:

Mars Og performs best with an attentive grower due to the cool Scottish outdoor climate and its susceptibility to late-season mould. Novice growers should expect to manage airflow and moisture carefully to avoid rot.

Flowering Time:

Indoor flowering typically completes in eight to nine weeks. Outdoors plants usually finish late September to early October in the UK.

Yield:

Yields are moderate to high under good conditions but can drop in damp, cool seasons. Proper feed and air circulation improve final harvest weight.

Height:

Plants show a sturdy, compact structure indoors and can reach one and a half to two and a half metres outdoors. Side-branching produces dense colas that benefit from selective topping.

Environment:

Indoors Mars Og responds well to training and controlled environments to maximise bud density. Outdoors in the Scottish Highlands it rewards careful site choice and protection from coastal winds.

Climate:

Growing Mars Og in the Scottish Highlands demands proactive mould prevention and wind shelter due to the cool Scottish outdoor climate. Choosing a sheltered, sun-facing site within the Scottish Highlands reduces weather stress and improves bud ripening.

Remove affected material immediately, improve airflow and consider harvesting early if rot spreads to adjacent flowers.
Common question Posted by Urbanseedbank Answered
Q
Should I use extra potassium in late bloom?
A
Verified answer
A modest boost of potassium and phosphorus in the final weeks helps resin production and bud finish, but avoid overfeeding.
