Description from Crop King Seeds

Strain Description
Granddaddy Purple autoflower combines deep-purple, resin-coated buds with a delightfully sweet grape and berry aroma accented by floral and herbal tones. Its indica dominance delivers a soothing, body-heavy high often accompanied by euphoric mental uplift. This strain’s compact stature and striking appearance make it as pleasing to grow as it is to consume .
Growing Information
This autoflower thrives both indoors and outdoors across temperate, continental, sunny, and Mediterranean climates. With its straightforward cultivation and fast 8–10 week cycle, growers can expect reliable resin-rich yields. Plants stay compact indoors (0–4 ft) and medium-sized outdoors (5–8 ft), showing good resistance to temperature changes.
Quick Grow Tips
Lighting: Maintain an 18/6 light cycle; autoflowers do not need a 12/12 switch.
Nutrients: Use moderate feeding—this strain is moderately demanding.
Watering: Provide balanced watering; avoid overwatering compact root systems.
Environment: Keep stable, moderate climates; avoid extremes to support healthy growth.
Summary
Granddaddy Purple autoflower seeds deliver compact, purple-hued blooms with sweet berry-grape flavor and 16–19 % THC, all in a quick 9–10 week cycle without light changes, perfect for mid-tier growers seeking potency in a small package.
