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.
Lumbar is an indica-dominant hybrid bred for compact growth and dense, resinous buds. The plant shows smoking characteristics that favour physical relaxation over energetic uplift.
THC usually sits between 18 and 22 percent, giving clear, reliable potency for most experienced users. Some phenotypes can edge higher under optimised greenhouse conditions.
CBD levels are very low, generally under one percent, so effects are driven primarily by THC. Those seeking high-CBD therapy should consider a different cultivar.
Lumbar descends from Northern Lights and Skunk, combining classic indica density with resilient vigour. The cross emphasises resin production and repeatable structure across phenotypes.
Seeds are feminised to simplify cultivation and guarantee flower-producing plants. Growers should still select for vigour and resistance when planning a mother or run.
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 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.
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.
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.
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.
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.
The high-THC profile delivers a calming, body-centred effect that eases tension without heavy cognitive distortion. As the session progresses it can move toward sleepiness for evening use.
The flavour profile blends earthy and pine notes with a bright citrus finish. Smoke is smooth with a lingering zesty aftertaste.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use 20–30 litre pots for single-plant greenhouse runs to balance root space and airflow, and ensure pots have good drainage.
Keep relative humidity below 55% during flowering and increase ventilation; use dehumidifiers in closed greenhouse setups where needed.
Harvest late September to early October in most coastal locations, adjusting for trichome maturity and local microclimate.
Feed moderately; the strain responds well to steady, balanced NPK with lower nitrogen in late flowering to encourage bud ripening.
Provide windbreaks and position plants away from direct salt exposure as salt can stress foliage and reduce vigour.
Yes, dense buds increase mould risk; prioritise airflow, leaf pruning and early detection to protect yields.
Low-stress training and SCROG work well to open the canopy and increase light penetration to side buds.
Dry slowly at stable 18–21°C and 45–55% RH, then cure in sealed jars with periodic burping to preserve flavour and aroma.
Yes, a small greenhouse suits Lumbar provided you manage ventilation and humidity, and maintain regular pest inspections.
Yes, greenhouse cannabis cultivation is ideal because it allows climate control to mitigate Devon's damp coastal climate and boost yields.
