Blue Blockers Strain Information and Characteristics
-
Strain Type:
Blue Blockers is an indica-dominant hybrid that favors calming body effects while keeping a gentle cerebral lift. Canadian growers often praise its dense buds and stable growth habit.
-
THC Content:
THC levels sit around 18 to 24 percent, making Blue Blockers suitably potent for evening use. Expect strength similar to many popular hybrids found across Canada.
-
CBD Content:
CBD stays low at roughly 0.5 to 1.2 percent, so therapeutic action relies mainly on the THC and terpene profile. Medical users in Canada choose it for symptom relief tied to the psychoactive fraction.
-
Grow Difficulty:
Growing Blue Blockers fits an intermediate skill level and rewards steady attention to humidity and airflow. You should practice training and pruning to manage its bushy structure in Canadian indoor setups.
-
Flowering Time:
Indoor flowering runs about eight to nine weeks before harvest. Outdoors, plants reach maturity by late September in southern Canada under a full season.
-
Expected Yield:
Expect medium to high yield under good light, around 450 to 550 grams per square metre indoors. Growers in BC and Ontario report solid outdoor weight when plants receive full season sun and timely feeding.
-
Plant Height:
Plants reach medium height at roughly 80 to 140 centimetres with a compact, branchy form. Use training to shape the canopy to fit common Canadian grow tents and maximize light spread.
-
Growing Environment:
Blue Blockers performs well both indoors and outdoors with predictable resin production. In Quebec growers move plants inside before early frost to protect buds.
-
Expected Effects:
Effects start with relaxed body sensations and a smooth uplift that eases tension. You will find it useful for late afternoon use that transitions toward sleep at higher doses.
-
Genetic Lineage:
Genetics read Blueberry x OG Kush, blending fruity terpenes with a kush backbone. Breeders at MasterSeeds select this cross for stability and terpene clarity.
-
Seed Type:
Seeds are offered feminized to give you predictable female plants and steady crop planning. MasterSeeds sells single seeds and multi-packs suited to growers across Canada.
-
Preferred Climate:
Blue Blockers prefers temperate to continental climates with warm days and cool nights for optimal colour and terpene expression. In prairie provinces protect plants from early fall frost and provide wind shelter.

Q: My plants stretch a lot in early veg. What do you suggest?
A: Increase light intensity and top at three to four nodes. Start low stress training to keep internodes compact.

Q: Leaves turn purple late cycle. Should I worry?
A: Purple tones often arise from cool night temperatures or slight phosphorus shifts. Test pH and reduce night temps by a few degrees to isolate the cause.

Q: Bud density drops in week seven. How to fix it?
A: Boost late-flower light and keep humidity in the 40 percent range. Add PK supplements during the final stretch to harden buds.

Q: Which indoor lights give best yield for this strain?
A: Full-spectrum LEDs that deliver 600 to 900 µmol/m2/s at canopy give strong results. Keep panels 30 to 45 centimetres above the canopy depending on output.
