About Kmac

Kmac is a dependable hybrid bred from Kush and MAC lines that offers a clear uplift followed by a steady, relaxed body high. It suits growers who want a resilient plant with citrus-forward flavours and good resin production, and it performs well both indoors and in temperate outdoor sites when moisture is managed.

Grow Difficulty:

Kmac is an intermediate grower that responds well to attentive care in damp conditions. In a wet Welsh valley climate growers should focus on airflow, pruning and disease prevention to avoid mould.

Flowering Time:

Flowering normally finishes in 8 to 10 weeks under stable indoor conditions. Outdoor crops in Durham typically fatten in late September to early October.

Yield:

Kmac produces a medium to high yield when fed well and kept dry. Expect 450 to 550 g/m² indoors and 400 to 600 g per plant outdoors with good conditions.

Height:

Plants stay medium to tall with a solid central cola and sturdy side branches. Outdoors they can reach up to 2.5 metres in long seasons but remain manageable with training.

Environment:

Kmac performs well both indoors and outdoors and is a reliable choice for growers around Durham. Indoor growers benefit from SCROG or SOG techniques while outdoor crops in Durham need shelter or raised beds to cope with rainfall.

Climate:

Growing Kmac in Durham requires vigilant moisture control because the wet Welsh valley climate encourages mould and bud rot. Use covered outdoor spaces, raised beds and consistent ventilation indoors to keep plants healthy in this climate.

How do you handle late-season rain?
