About Blue Shamu

Blue Shamu is a compact, resinous hybrid bred for indoor growers and sheltered outdoor sites. It combines sweet blueberry and citrus notes with a balanced, calming high and finishes in eight to ten weeks under good conditions.

Grow Difficulty:

Under a temperate southern England climate this variety is best suited to growers with some experience. It tolerates mild variation but benefits from steady humidity and airflow control.

Flowering Time:

Flowering usually completes within eight to ten weeks indoors. Outdoor growers should expect a similar schedule, finishing before the heaviest autumn weather.

Yield:

Indoor yields are medium to high when trained and fed consistently. Outdoors plants can deliver larger colas in a protected site during a good season.

Height:

Plants stay relatively compact in controlled environments but will stretch outdoors if given space. Expect finished heights around 80–150 cm indoors with the potential to exceed that outdoors.

Environment:

Indoors Blue Shamu responds well to SCROG and LST and fits most tents cleanly. Outdoors in Devon it benefits from sheltered, south-facing spots and typically finishes before persistent autumn rain.

Climate:

Growing Blue Shamu in Devon requires attention to the temperate southern England climate and late-season rain. Good ventilation and timely harvesting reduce the risk of mould in that environment.

Should I flush before harvest?
