Sweetwater 420 is a sativa-dominant hybrid that leans toward energetic daytime use. MasterSeeds positions it as a balanced option for growers seeking clarity with mild body ease.
THC sits around 18 to 22 percent in typical pheno expressions. That level gives you clear uplift with a light body buzz for daytime tasks.
CBD is low at about 0.5 to 1 percent across most plants. Low CBD makes Sweetwater 420 better suited for symptom relief that relies on THC effects.
Growing Sweetwater 420 rates as intermediate and rewards steady environment control. In Canadian setups you should monitor humidity during flowering to reduce mould risk.
Indoor flowering runs eight to nine weeks for most plants. Outdoor growers in temperate zones harvest near late September to early October.
Indoor yields reach 450 to 550 grams per square metre under good lights. Outdoor runs in regions like BC and Ontario have produced 600 to 900 grams per plant under long seasons.
Plants reach a medium-tall stature from ninety to 160 centimetres. You should use training to keep an even canopy in indoor rooms.
Sweetwater 420 performs well indoors and outdoors with proper care. Shelter outdoor plants from heavy rain and early frost in cool climates.
Effects begin with an uplifting cerebral boost that sharpens focus. A mild body relax follows and keeps the overall ride balanced for daytime use.
Genetics trace to Sweet Tooth x Northern Lights. That cross provides sweetness up front with stable resin production through flowering.
Seeds come feminized to give predictable female plants for your grow. MasterSeeds lists clear germination and phenotype guidance with each pack.
Best performance occurs in temperate and Mediterranean climates with warm days and cool nights. In prairie regions you should position plants in a protected site to avoid early frost.
