About Devil Xxl

Devil Xxl is a resilient indica-dominant hybrid that combines heavy yields with pronounced trichome production. It performs well both indoors and outdoors in a mild southern growing climate and rewards careful humidity and airflow management with compact, resinous flowers.

Grow Difficulty:

Growing Devil Xxl is best described as intermediate and it responds well to standard pruning and training methods under a mild southern growing climate. Attention to humidity and airflow will make a marked difference to final quality.

Flowering Time:

Flowering takes around eight to ten weeks under stable conditions. Expect thick calyx development during the final three weeks as trichome production increases.

Yield:

Yields are generous when plants receive steady nutrition and appropriate light levels. Outdoor crops in a good season can match or exceed indoor yields per plant.

Height:

Plants show a medium-to-tall structure with strong central colas and side branching. The internodal spacing is compact enough to support heavy bud loads with timely support.

Environment:

Indoors, Devil Xxl performs well under 600–1000 W HID or equivalent LED rigs with SCROG or topping techniques. Outdoors in Cambridgeshire the strain benefits from a sheltered site and extra support for heavy buds.

Climate:

Growing Devil Xxl in Cambridgeshire with a mild southern growing climate rewards steady, even development and reliable resin production. The strain tolerates the region's variable weather but benefits from protection during wet or windy periods in Cambridgeshire.

Common question Posted by Urbanseedbank Answered
Q
How often should I water my outdoor Devil Xxl in summer?
A
Verified answer
Water when the top 2–3 cm of compost is dry, generally every 2–3 days in warm weather, and more sparingly after heavy rain.
Common question Posted by Urbanseedbank Answered
Q
What support do the heavy colas need outdoors?
A
Verified answer
Use stakes or trellis netting before buds become too heavy to minimise stem breakage.
Common question Posted by Urbanseedbank Answered
Q
Should I defoliate the lower branches?
A
Verified answer
Remove only non-productive fan leaves to improve airflow; avoid aggressive defoliation that shocks the plant.
Common question Posted by Urbanseedbank Answered
Q
What flushing routine do you follow before harvest?
A
Verified answer
I run plain pH-balanced water for 7–10 days before harvest to clear excess nutrients and improve flavour.
Common question Posted by Urbanseedbank Answered
Q
Do you recommend any foliar feeds?
A
Verified answer
Foliar feeds during veg can help, but avoid spraying during flowering to reduce mould risk and residue on buds.
