About Lumbar

Lumbar is an indica-dominant hybrid bred from Northern Lights x Skunk that favours dense bud formation, resin production and a calming, sedative effect profile. It performs best in controlled greenhouse environments or sheltered outdoor sites where attention to humidity and airflow reduces mould risk. The strain finishes in eight to nine weeks and delivers medium-high yields under good cultural practices, making it a strong choice for growers in damp coastal regions seeking reliable, evening-oriented medicine.

Grow Difficulty:

Cultivation difficulty is intermediate and benefits from structured training and consistent nutrient schedules. In a damp coastal climate extra vigilance for mould and ventilation is essential.

Flowering Time:

Flowering typically completes in eight to nine weeks under stable light cycles. Outdoor growers should expect a late-September to early-October finish in mild seasons.

Yield:

Yields are medium to high in well-managed greenhouses and more moderate outdoors. Mother plants and SCROG techniques can substantially boost per-square-metre results.

Height:

Plants remain medium in height with a sturdy central cola and several side branches. The compact habit makes Lumbar suitable for growers aiming for discreet, productive crops.

Environment:

Under glass in Devon Lumbar responds well to controlled temperature and steady airflow. Outdoors in Devon the variety benefits from sheltered sites and careful mildew prevention.

Climate:

Growing Lumbar in Devon requires attention to the region's damp coastal conditions and variable winds. Adequate drainage, raised beds in outdoor plots and vigorous greenhouse ventilation are key to preventing mould.
