About Black Triangle

Black Triangle brings together indica structure and Kush-derived resin to produce compact plants with heavy, aromatic colas. Suited to growers who can control humidity, this variety rewards careful canopy management with terpene-rich yields.

Grow Difficulty:

Growers with intermediate experience will find Black Triangle rewarding but not forgiving. Watch ventilation and humidity closely because damp coastal climate increases the risk of mould.

Flowering Time:

Flowering typically completes within eight to ten weeks under good conditions. Allow time for final trichome maturation rather than rushing harvest.

Yield:

Yields are medium to high indoors with careful canopy management. Outdoor or greenhouse yields depend heavily on season length and humidity control.

Height:

Plants remain relatively compact with bushy side branches that respond well to training. Expect a final height suited to tents or smaller greenhouses.

Environment:

Indoors it performs well in a controlled environment and fits standard grow tents. In Devon, outdoor cultivation benefits from a greenhouse or sheltered position to cut wind and damp exposure.

Climate:

Growing Black Triangle in Devon requires attention to damp coastal conditions and ventilation. Position plants in a well-ventilated greenhouse or indoors with dehumidification to prevent mould in the damp coastal climate.

Q
I'm growing Black Triangle in a small Devon greenhouse; what ventilation do I need?
A
Verified answer
Ensure continuous low-level airflow with an extractor fan and passive vents; add a small oscillating fan inside to keep air moving around bud sites.
Common question Posted by Urbanseedbank Answered
Q
How should I adjust feed in late flowering?
A
Verified answer
Cut back nitrogen and maintain phosphorus and potassium to encourage bud ripening while avoiding overfeeding that can lock out nutrients.
Common question Posted by Urbanseedbank Answered
Q
I see early bud mould, what now?
A
Verified answer
Remove affected sections, increase airflow and drop humidity quickly; if widespread, consider harvesting early to save unaffected tops.

Do I need supplementary heat in Devon?
A

Supplementary heat can help during cold, damp spells but avoid high night temperatures that stress plants; keep a steady day-night cycle.
