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.

Grow Difficulty:

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 Time:

Flowering takes around 8 to 10 weeks. Late trimming can improve light penetration and bud density.

Yield:

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.

Height:

Plants remain medium in height with compact central colas. They respond well to topping and low-stress training to open the canopy.

Environment:

Indoors in Nottingham the strain performs reliably with controlled climate. Outdoors in Nottingham a greenhouse or dry late season will greatly improve bud quality.

Climate:

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.

Common question Posted by Urbanseedbank Answered
Q
How do you handle humidity spikes late in flower?
A
Verified answer
I run a dehumidifier on a timer, pull in drier air during the day and use fans to keep air moving over the canopy.
Common question Posted by Urbanseedbank Answered
Q
Do you top Sour Sleep or just low-stress train?
A
Verified answer
I top once early and then use LST; that creates even colas and reduces the need for heavy defoliation later.

Q
What feeding schedule works best?
A
Verified answer
Moderate veg feed for three to four weeks, then switch to bloom nutrients and taper off two weeks before harvest for a cleaner smoke.

Look for discoloured, fuzzy patches in dense bud sites and a musty smell, especially after wet spells or humidity spikes.
