Gg4 delivers high THC effects and dense, resinous buds in a compact plant. Expect 8 to 9 weeks of flowering and indoor yields near 400 to 600 g per m2 with proper training. Plants respond well to topping and SCROG and need strict humidity control during late flower to avoid mould. Medically Gg4 supports pain relief, sleep and stress reduction for many patients in Canadian programs.

Gg4 is an indica-dominant hybrid with heavy resin production. Canadian growers often label it a night-time staple for strong effects.
Gg4 tests high for THC, typically between 24 and 28 percent. This level sits above many Canada-popular strains and produces marked potency.
Gg4 has low CBD, usually under 1 percent. Medical users in Canada select it for THC-driven symptom control rather than CBD therapy.
Growing Gg4 requires steady nutrient control and strict humidity management. In Canadian seasons you should monitor light and temperature during late flower to avoid mould.
Gg4 flowers in about 8 to 9 weeks indoors. Outdoor growers in Canada often harvest in early October in temperate zones.
Indoor yields typically range from 400 to 600 grams per square metre with tuned feeding and training. Outdoor plants can reach similar totals per plant in favourable BC and Ontario sites.
Plants stay medium in height indoors at 80 to 140 cm. Outdoors they can reach up to 2 metres in open, sheltered locations.
Gg4 thrives under controlled indoor light and nutrient regimes. It also performs outdoors in temperate Canadian regions with a dry late summer.
Expect a fast euphoric lift that shifts into deep relaxation. Many Canadian users prefer Gg4 for evening unwinding and persistent pain relief.
Gg4 descends from Chem's Sister x Sour Dubb lineage. Breeders at MasterSeeds select stable cuts for resin and yield consistency.
These seeds come as feminized genetics for predictable female plants. MasterSeeds sells them in common pack sizes for home growers in Canada.
Gg4 prefers temperate to continental climates with a dry late summer. It suits coastal BC and sheltered Ontario gardens while needing wind and frost protection in prairie zones.
