About Blue Coffin
Blue Coffin is an indica-dominant hybrid that pairs sweet blueberry aroma with earthy, diesel undertones. It performs well in controlled indoor environments and sheltered outdoor sites in the milder parts of the UK, producing compact, resin-rich flowers that suit both recreational and medicinal users.
Grow Difficulty:
Growing Blue Coffin is intermediate in difficulty and rewards attentive growers in a mild southern growing climate. It tolerates training well but needs regular pruning and moisture management to avoid mould.
Flowering Time:
Flowering takes around eight to nine weeks indoors depending on phenotype. Outdoors it is typically ready by late September in similar latitudes.
Yield:
Yield is medium to high with proper training and nutrient management. Indoor growers can expect around 400–500 g/m2 while outdoor plants can be larger in favourable conditions.
Height:
Plants are medium to tall with a sturdy central cola and lateral branching. Expect a bushy canopy if not topped or trained.
Environment:
Indoors Blue Coffin responds well to SCROG and SOG methods, producing dense buds under controlled conditions in Cambridge. Outdoors it thrives in sheltered spots and can reach larger sizes in Cambridge gardens or allotments when protected from wind.
Climate:
Growing Blue Coffin in Cambridge benefits from the area's mild southern growing climate, which extends the outdoor season and reduces frost risk. However, growers must still manage humidity and airflow to prevent mould during damp spells in Cambridge.
