About Sour Sleep
Sour Sleep is an indica-dominant hybrid bred from Sour Diesel x Northern Lights, designed for evening use and restorative sleep. It offers a sour, diesel-forward flavour with medium to high THC and a sedative finish, performing best indoors or in protected outdoor setups where humidity is controlled.
Sour Sleep is an indica-dominant hybrid. It favours sleep-promoting effects while keeping a sharp sour terpene profile.
THC typically sits between 18% and 22%. That level gives a clearly psychoactive hit without extreme unpredictability.
CBD is low, generally under 1%. This strain is not chosen for CBD therapy but for THC-driven sleep aid.
Sour Sleep descends from Sour Diesel x Northern Lights. That pairing explains the tart aroma and steady body relaxation.
Seeds are feminized photoperiod varieties. Treat them as standard photo plants with a vegetative phase before switching to bloom.
Under humid indoor grow rooms Sour Sleep presents moderate difficulty for growers. Good ventilation and dehumidification are essential to avoid mould in those conditions.
Flowering takes around 8 to 10 weeks. Late trimming can improve light penetration and bud density.
Yields are medium to high indoors and can reach up to 450 g/m² under optimal conditions. Outdoor results depend heavily on season length and humidity control.
Plants remain medium in height with compact central colas. They respond well to topping and low-stress training to open the canopy.
Indoors in Nottingham the strain performs reliably with controlled climate. Outdoors in Nottingham a greenhouse or dry late season will greatly improve bud quality.
In Nottingham, humid indoor grow rooms require strict humidity control when cultivating Sour Sleep. Use dehumidifiers and timed ventilation to cut mould risk and stabilise bud development.
Effects arrive with a brisk euphoric lift and settle into heavy relaxation. The final phase is sedative, making it suitable for evening use.
The flavour profile is dominated by sour citrus and diesel notes. A piney, earthy aftertaste rounds out the smoke.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Sour Sleep prefers steady temperatures around 20-24°C and relative humidity below 50% during flowering, with strong air movement to prevent mould.
It is suitable for growers with some experience; it tolerates training but needs attention to humidity and trimming to avoid bud rot.
Harvest when trichomes are mostly cloudy with some ambers for sedative effects, typically at 8-10 weeks of flowering.
Start with moderate nitrogen in veg and switch to higher phosphorus and potassium in bloom, reducing overall feed in the final two weeks for flushing.
Yes, but outdoor growers in the UK should use a greenhouse or pick a dry microclimate as prolonged humidity increases rot risk.
Selective defoliation to improve airflow and removing lower growth helps prevent mould and focuses energy on top colas.
Spider mites and fungus gnats are the most common indoors, so monitor regularly and use biological controls where possible.
Dry slowly to a stem snap, then cure in jars at 60-62% RH, burping daily for two weeks then less frequently for several weeks.
Many patients use it for sleep and pain; consult clinical guidance and start with a low dose due to its THC content.
For northern climate cannabis growing focus on humidity control, greenhouse protection and strain selection to ensure a dry finish.
