Black Runtz Strain Information and Characteristics
-
Strain Type:
Black Runtz is a balanced Hybrid combining indica density with sativa lift. Canadian growers describe it as a dessert-style hybrid with dark, resinous buds.
-
THC Content:
Black Runtz tests high for THC, typically between 22% and 28%. That potency rivals many popular Canadian strains and delivers a clear cerebral lift with body ease.
-
CBD Content:
CBD stays low in Black Runtz, generally under 1%. Low CBD means therapeutic use relies on THC-driven relief within Canada’s medical market.
-
Grow Difficulty:
Growing Black Runtz requires intermediate skill and steady feeding. Many Canadian growers use controlled indoor rooms or greenhouses to manage resin and trichome development.
-
Flowering Time:
Flowering usually finishes in 8 to 10 weeks under indoor lights. Outdoor producers in southern Canada harvest by late September to early October.
-
Expected Yield:
Indoor yields reach roughly 450 to 550 g per square metre with good training. Outdoor plants produce large colas in a long season, especially in BC and Ontario gardens.
-
Plant Height:
Plants reach medium height, usually 80 to 140 cm. That size fits common Canadian grow tents and backyard spaces.
-
Growing Environment:
Black Runtz performs well indoors under controlled light cycles. Outdoors it thrives in sheltered, warm sites and in greenhouse setups across Canada.
-
Expected Effects:
Expect a strong euphoric lift that settles into a relaxed body feel. Many Canadian consumers prefer it for social use and evening sessions.
-
Genetic Lineage:
Black Runtz traces to Zkittlez x Gelato genetics. Breeders select dark-phenotype parents to enhance colour and resin.
-
Seed Type:
This line is sold as feminized seed for predictable female crops. Seed packs for Canadian growers include clear germination and grow guidance.
-
Preferred Climate:
Best climate is temperate to warm with long light periods. In Canada, greenhouse or indoor setups suit prairie and northern regions while BC benefits from coastal warmth.
