Sour CreamStrain, Effects, Genetics, Grow Guide & Where to Buy
Sour Cream earned its place in the modern cannabis canon for a reason , and the genetics live up to the reputation. It is a sativa-dominant (17% indica / 83% sativa) testing at roughly 26% THC, with a flowering window of 8-10 weeks under a 12/12 photoperiod. Below we walk through what to expect from the high, how the plant grows in a tent or outdoor garden, the parental genetics behind the cultivar, and how to get Sour Cream seeds delivered anywhere in the US.

Sour CreamEffects & Experience
The dominant effects of Sour Cream are creative, calm, and the experience is more nuanced than a simple high/low/sedating label would suggest. Onset is gradual rather than abrupt, the peak holds for roughly an hour, and the comedown is smooth, which is why this strain shows up in so many "daily driver" lists from experienced consumers.
Growing Sour Cream
Growing Sour Cream fits long-season outdoor zones, Southern California, Arizona, Texas, and Florida, where the extra 2-3 weeks of finishing time is available. Sour Cream is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola; and feed cal-mag from week 2 onward at 2-3 mL per gallon, most reverse-osmosis and soft tap water setups need it. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
