Colombian Haze

It can be grown under short season outdoor conditions but it prefers a longer season; start early under lights or choose a sheltered, sunny microclimate to improve ripening.

Plant outside after the last risk of frost, typically late May or early June in most UK areas, and consider starting seedlings under cover to get a head start.

Use windbreaks, stakes and low-profile training to reduce leverage on branches and prevent wind burn and stem breakage.

It needs moderate feeding through the vegetative phase and lighter inputs late in flowering to avoid harsh smoke.

Watch out for aphids, spider mites and bud mould, especially in damp conditions; regular inspection and good airflow help prevent problems.

Provide stable late-flower temperatures, reduce nitrogen and consider short, controlled stress like mild drought before harvest to concentrate terpenes.

Dry slowly at 16–20°C with moderate humidity for 7–14 days, then cure in jars for at least four weeks for improved smoothness and flavour.

In the UK expect harvest around late September to early October for well-sited plants, earlier in sheltered microclimates.

Yes, strong mother plants root well, but choose vigorous, disease-free mothers for reliable cuttings.

Topping, low stress training and selective defoliation help produce an even canopy and reduce wind exposure on tall stems.
