Blue Steel Strain Information and Characteristics
-
Strain Type:
Blue Steel is an indica-dominant hybrid that leans toward calming physical effects. The structure suits growers who want dense buds and stable trichome production.
-
THC Content:
Typical THC ranges from 18 percent to 24 percent in tested phenotypes. At that level you will get a strong head effect that moves into deep body relaxation.
-
CBD Content:
CBD stays below 1 percent in most samples, so expect a THC-forward profile. Patients in Canada report use for sleep and short-term pain when THC treatments match a care plan.
-
Grow Difficulty:
Blue Steel fits intermediate growers who manage nutrient levels and airflow. You should monitor humidity during late flowering to avoid bud rot.
-
Flowering Time:
Indoor flowering completes in eight to ten weeks for most phenotypes. Outdoor plants finish late in the season, often by late September in temperate zones.
-
Expected Yield:
Indoor yields reach 450 to 500 grams per square metre under strong lighting and standard feeds. Outdoors plants produce up to 600 grams per plant in long, sunny seasons.
-
Plant Height:
Plants stay medium sized indoors, typically 80 to 140 centimetres with slight topping. Outdoors they will stretch and can reach two metres when left to full growth.
-
Growing Environment:
Blue Steel performs well under LED or HPS lights and adapts to outdoor beds and large pots. You will find it reliable on balconies and in greenhouses with good ventilation.
-
Expected Effects:
The high opens with clear mental uplift before settling into heavy physical calm. Many users note improved focus for short tasks followed by sleep readiness.
-
Genetic Lineage:
Blue Steel derives from Blueberry x OG Kush genetics in its core cross. The breeding brings fruity terpenes and a sturdy bud structure.
-
Seed Type:
This line is offered as feminized seeds to secure female-only crops and uniform phenos. You will see predictable flowering windows and stable growth patterns.
-
Preferred Climate:
Blue Steel prefers temperate to Mediterranean climates with warm days and cool nights. It tolerates mild cool spells but needs a frost-free outdoor season.
