About Dark Rainbow
Dark Rainbow is an indica-dominant hybrid developed from Northern Lights x Blueberry to handle cooler, maritime climates. It produces dense, resinous buds with dark-berry aromas and an earthy-spice finish while remaining manageable for intermediate growers.
Grow Difficulty:
Grow difficulty is intermediate and this variety tolerates humidity but needs vigilant mould prevention during a rainy autumn harvest season. Regular pruning, good airflow and close inspection in the run-up to harvest are essential.
Flowering Time:
Flowering normally completes in eight to ten weeks under good conditions. Outdoor crops in northern areas will usually finish in late autumn.
Yield:
Yield is moderate to high for its footprint with indoor growers often hitting 400-550 g/m2. Outdoors, sheltered sites can produce around 300-400 g per plant under favourable conditions.
Height:
Plants remain relatively compact, typically reaching 0.8 to 1.6 metres. The sturdy branches support heavy, resinous colas without excessive stretching.
Environment:
Indoors Dark Rainbow responds well to SCROG and low-stress training and rewards careful nutrient management. Outdoors in Perthshire it benefits from a sunny, sheltered spot to reduce wind and rain exposure.
Climate:
In Perthshire growers should plan carefully because this line often finishes during a rainy autumn harvest season. Choose sheltered outdoor sites or arrange an indoor finish to reduce the risk of bud rot in Perthshire.
