About Blue Blockers

Blue Blockers is an autoflowering cultivar combining Blueberry x Northern Lights genetics to produce compact, resinous plants that finish quickly. It suits growers who need a dependable, medium-yielding strain that handles exposed sites with correct support and wind protection.

Grow Difficulty:

Grow difficulty is intermediate and plants tolerate variable conditions but benefit from attentive support. In windy coastal growing areas you should use staking and windbreaks to protect branches and prevent bud damage.

Flowering Time:

Flowering finishes quickly, typically within seven to nine weeks indoors. Outdoors the early finish suits growers aiming to avoid autumn weather.

Yield:

Yields are moderate with dense, THC-rich flowers that respond well to correct feeding and support. Expect reasonable returns per plant rather than very large harvests.

Height:

Plants remain short to medium in height and form sturdy, broad colas. The compact structure suits restricted spaces and discreet plots.

Environment:

Indoors Blue Blockers performs well in tubs and controlled environments with standard nutrients. Outdoors in Fermanagh the early finish and compact size are advantages for growers dealing with exposed sites.

Climate:

In Fermanagh and other exposed sites Blue Blockers benefits from early planting and wind protection. In windy coastal growing areas use solid windbreaks and consider pots to move plants when storms approach.

Any tips for trimming before harvest?
A

Trim larger fan leaves for airflow during late flowering but save final detailed manicures until after a short dry to keep trichomes intact.
