PPD Auto is the autoflower edition of P.P.D., the Humboldt Seed Company original formerly known as Purple Panty Dropper. This indica-dominant strain combines rich purple color, a sweet floral grape aroma and 18-25% THC, and it runs from seed to harvest in about 100 days.
The breeder describes PPD as reliable: the seeds produce big plants with uniform growth and great yields. The buds are moderately dense and saturated in deep purple, making it one of the more photogenic autos in the Humboldt Seed Company catalog.
The aroma is thick, sweet and floral, often compared to concord grapes. True to the strain’s old name, the smoke carries a playful, romantic reputation, and Humboldt Seed Company reminds everyone that consent always comes first.
Although indica dominant, PPD is nicely balanced with sativa influence, and the effect is listed as euphoric and mood lifting. The line is listed as Bx8, reflecting years of backcrossing to keep its color and character consistent.
Lineage and Breeding of PPD Auto
The auto parentage is listed as Matanuska Mist x Purple Panty Dropper x Sour Apple Auto. Purple Panty Dropper supplies the signature purple hue and floral grape aroma, Matanuska Mist adds structure and vigor, and Sour Apple Auto brings the autoflowering trait.
As a Humboldt Seed Company signature strain, PPD also appears in other parts of the breeder’s lineup, including as a parent of Strawberry Cheesecake. The Bx8 generation listed for this auto points to a long, steady breeding effort aimed at uniform plants and dependable results.
Aroma, Flavor and Effect
The jar releases a sweet, floral bouquet with concord grape at its heart. The smoke is smooth and perfumed, with grape candy sweetness on the inhale and soft floral notes that linger on the exhale.
The effect is described as euphoric and mood lifting, with an indica-leaning body feel balanced by a bright headspace. With THC listed at 18-25%, it offers solid strength without going to extremes, which makes it a versatile option for evenings with friends or a relaxed date night.
Its color is a conversation starter as much as its aroma. Well-grown buds show rich purple tones that hold up beautifully after drying and curing.
Growing PPD Auto Indoors and Outdoors
PPD Auto blooms automatically, so keep indoor lights at 18/6 or 20/4 throughout the run. The breeder lists about 100 days from seed to harvest, a longer window that gives these big plants time to build size and yield.
Use final containers of 5 gallons (19 L) or more and start LST early to keep the canopy even. Uniform growth makes it easy to manage several plants side by side. Slightly cooler night temperatures in late flower can help bring out the purple coloration.
Outdoors, sow after the last frost and expect harvest roughly three months later. The plants grow big, so give them full sun, plenty of root space and steady feeding. Good airflow around the moderately dense buds keeps them clean toward the finish.
