Appearance of the plants

The plants grown from these cannabis seeds show two possible looks depending on the phenotype. The first phenotype, called Rocketman, is more compact: a smaller plant with a very dense main cola and only a few side buds. The structure is stout and tight. The second phenotype, Lilla, tends to stretch taller — up to around 120 cm — and produces dense buds that can turn purple. Those buds are thick and coated in resin, sometimes sparkling under light. The leaves, stalks, and overall plant shape reflect whether you got the shorter, chunky type (Rocketman) or the taller, resin-heavy purple type (Lilla).

The taste & smell

The aroma of Sour 71 leans toward sour and tangy vibes, mixed with a hint of spicy or funky undertones — like a sour candy with a little bite. The scent can carry subtle earthy or pungent notes, but overall it’s sour-forward. When you break open the buds, that sharp, slightly sour bouquet becomes noticeable. If you’ve got the Lilla phenotype, the purple buds plus resin make the aroma even richer, kind of like a sharp citrus twist combined with herbal depth.

Effects

When grown and used properly, Sour 71 gives a clear, uplifting sativa-leaning effect, with energy and a light, happy buzz rather than heavy sedation. Because it’s a sativa-dominant autoflower, you might get a more head-focused high — a gentle spark of creativity or clarity, perfect for a relaxed but alert mood. There is no official THC or CBD percentage listed for this strain, so strength may vary depending on phenotype and growing conditions. But from its genetic heritage, expect something lively and clear rather than heavy and drowsy.

Growing characteristics/yield

Sour 71 is a fast finishing strain: from seed to harvest usually takes around 71 days. With these cannabis seeds you can grow indoors or outdoors. The typical plant height ranges from 50 up to 120 cm depending on phenotype. Yield per plant often falls between about 20 to 70 grams when grown indoors or outdoors under normal conditions. Because of its autoflower nature and mixed genetics, it tends to grow reliably and fairly fast, so even growers who don’t have much time can get a decent harvest without too much fuss.
