About Ultra Violet
Ultra Violet is an indica-dominant hybrid prized for its purple hues and dense, resinous buds. It offers a calming body effect with an uplifting cerebral edge early on and a sedating close that benefits sleep and pain relief. The strain performs well indoors and outdoors when growers manage humidity and provide shelter from heavy rain. Growers in Kent and similar climates should focus on airflow, drainage and organic soil health to get the best results.
Ultra Violet is an indica-dominant hybrid with pronounced purple buds. It combines dense flowers with a compact, bushy structure.
THC levels usually sit between 18 and 22 per cent, offering a noticeable potency. This range favours experienced users seeking a strong but controllable effect.
CBD content is low, typically below one per cent. The overall balance prioritises THC-led effects over CBD modulation.
Ultra Violet traces back to Granddaddy Purple crossed with Northern Lights. That lineage explains both the purple colouration and robust resin production.
Seeds are commonly supplied as feminised to ensure predominantly female plants. Regular seeds may be offered by some breeders for breeding or preservation.
Under the wet Welsh valley climate this variety needs attentive mould prevention and stable airflow. Regular training and careful humidity management reduce the risk of bud rot.
Flowering generally completes in eight to ten weeks under steady conditions. Trichome development intensifies in the final two weeks.
Outdoors in a protected site plants can deliver medium to high yields. Indoors yields are consistent when growers control feeding and humidity.
Plants remain medium in height with a dense canopy and strong lateral branching. They respond well to topping and low-stress training.
Ultra Violet grows well in controlled indoor tents and also outdoors when given shelter in Kent. In Kent outdoor plants need protection from prolonged rain and late-season damp.
Growing Ultra Violet in Kent with wet Welsh valley climate requires strict humidity control and good drainage. Select ventilated sites and consider raised beds or containers to reduce waterlogging.
The high-THC profile produces a calm, relaxing body sensation combined with a steady cerebral uplift. Sedation tends to increase later in the session, helping users unwind.
Flavours lean to sweet grape and ripe berry with an earthy base. The finish leaves a mild herbal bitterness.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
A loam-based, well-aerated soil rich in organic matter and with good drainage works best.
Use compost, worm castings and slow-release organic fertilisers, encourage soil biology with teas, and avoid synthetic nutrients.
If you follow a nutrient schedule, flush with plain pH-balanced water for the final one to two weeks.
Improve airflow, remove dense lower foliage, use dehumidification indoors and choose sheltered outdoor spots.
Low-stress training and topping open the canopy and reduce shaded spots where rot can form.
Aphids, spider mites and slugs are common; regular inspection and biological controls help manage them.
Aim for a soil pH between 6.0 and 6.5 for reliable nutrient uptake.
Yes, but use regular seeds for breeding as feminised seeds will not produce males for crosses.
Provide around 18 hours for veg and 12 hours for flowering with strong LED or HPS lighting.
Harvest before prolonged autumn rains, typically late September to early October in sheltered Kent locations.
