Blue Kush

Use full-spectrum LED or HPS lighting with roughly 18/6 for veg and 12/12 for flowering; keep canopy distance appropriate to avoid light stress.

Aim for 40-50% RH in late flowering and 50-70% during veg; use ventilation, dehumidifiers and careful watering to prevent mould.

It can be grown outdoors in sheltered, dry climates but in the UK it is safer in a greenhouse or indoors due to damp weather.

Monitor trichomes and expect harvest after about eight to ten weeks of flowering when most trichomes are milky with some ambers.

A balanced N-P-K program for veg and higher phosphorus and potassium in bloom works well; avoid overfeeding which increases mould risk.

Low-stress training and topping early will create an even canopy; use SCROG or LST in small spaces to maximise light penetration.

Yes, Blue Kush's compact stature and branching respond well to training, making it a strong candidate for small indoor cannabis grow spaces with controlled environment.

Routine inspection, good hygiene and beneficial predators or approved organic treatments keep pests under control in greenhouse settings.

Many growers flush for 7-14 days before harvest to improve smoke quality, but timing depends on trichome development and taste preference.

Yes, dense buds make it susceptible to bud rot in humid conditions, so keep airflow, spacing and RH under strict control.
