Chem 4 Strain Information and Characteristics
-
Strain Type:
Chem 4 is an indica-dominant hybrid with a strong Chemdawg profile. Canadian growers often describe this type as chemical and resinous with solid bag appeal.
-
THC Content:
Chem 4 typically registers high THC between 18 and 24 percent. That level sits above many everyday strains popular in Canada and gives an intense psychoactive experience for experienced users.
-
CBD Content:
CBD content in Chem 4 runs very low, usually under one percent. Medical patients in Canada select this strain for THC-driven symptom relief rather than CBD therapy.
-
Grow Difficulty:
Growing Chem 4 fits growers with intermediate experience due to stretch and resin management. You should monitor humidity and nutrients closely when growing under Canadian indoor setups.
-
Flowering Time:
Indoor flowering usually completes in 8 to 10 weeks. Outdoor harvest arrives in late September to early October across much of Canada.
-
Expected Yield:
Indoor yields tend to range from 450 to 600 grams per square metre under strong light. Outdoor plants produce 400 to 700 grams per plant in long, warm seasons such as BC and southern Ontario.
-
Plant Height:
Plants hold a medium height indoors at about 80 to 140 centimetres. Outdoors they often reach up to 160 centimetres in open sun.
-
Growing Environment:
Chem 4 performs well both indoors and outdoors with proper training and airflow. You should train the canopy indoors and select sunny, sheltered sites outdoors in Canadian regions.
-
Expected Effects:
Expect an initial cerebral lift that settles into a calm, body-focused buzz. Many Canadian consumers prefer this balance for social and creative use.
-
Genetic Lineage:
Genetics trace back to concentrated Chemdawg lines. The profile is listed as Chemdawg x Chemdawg to reflect its chemical lineage.
-
Seed Type:
These seeds are offered as feminized for predictable single-sex crops. MasterSeeds supplies germination notes and legal guidance for Canadian growers.
-
Preferred Climate:
Best performance appears in temperate climates with warm, sunny summers. It thrives on the BC coast and in protected outdoor sites across Ontario and prairie summers when heat is steady.
