About White Walker

White Walker is an indica-dominant hybrid bred for stable growth and reliable resin production. It favours medium height and compact structure, making it suitable for tent grows under LEDs and for outdoor sites with a warm, sheltered microclimate. With THC commonly between 18–22% and CBD below 1%, it provides a clear uplift followed by gentle body relaxation, useful for evening use. Growers in Northamptonshire and similar UK regions will benefit from good ventilation and humidity control, especially during late-season damp spells. Overall, White Walker rewards attentive growers with solid yields and a distinctive pine-mint-citrus flavour profile.

Grow Difficulty:

Growing White Walker is moderately challenging for those adapting to variable British weather. Attention to ventilation and humidity management reduces mould risk during damp spells.

Flowering Time:

Flowering normally completes in eight to ten weeks under stable indoor conditions. Outdoor crops in Northamptonshire generally finish by early autumn with careful timing.

Yield:

Indoor yields are medium to high when fed correctly and given ample light. With strong LEDs and adequate canopy management yields can reach 400–550 g/m².

Height:

Plants tend toward medium height with a bushy, compact structure. They respond well to topping and low-stress training to manage stretch.

Environment:

Indoors in Northamptonshire White Walker benefits from consistent environmental control and strong LED lighting. Outdoors in Northamptonshire it prefers a sunny, sheltered site and a long warm run-in to ripen fully.

Climate:

Growing White Walker in Northamptonshire requires planning around the county's variable British weather. Extra protection such as a greenhouse or cloches helps manage rain and late-season temperature drops in Northamptonshire.

Q
I have a 600W LED in a 1.2m² tent. How many White Walker plants should I run?
A
Verified answer
Two to four plants suits that tent size with a 600W LED; use training to fill the canopy without overcrowding.

Q
Leaves are yellowing mid-flower, what now?
A
Verified answer
Check for nutrient lockout and pH drift, then adjust feed and pH; late-stage yellowing can be natural but watch for deficiency signs.
