Growing Guide

This strain has a short flowering time of 8 to 10 weeks, making it ideal for growers looking to harvest quickly. It can be cultivated both indoors and outdoors under optimal conditions. To ensure successful growth, follow a careful germination process that avoids direct contact with the seeds and maintains consistent warmth and moisture.

Germination Steps:

• Set Up Your Germination Station: Moisten two paper towels with room temperature water. Place the seeds on one towel, cover with the second, and store in a warm, dark location.
• Monitoring: Check the paper towels every 4–6 hours to ensure they remain moist. Germination should occur within 24 to 120 hours.
• Ideal Conditions: Keep the germination area at 69.8 ºF – 78.8 ºF (21 ºC – 26 ºC), using purified water with a pH of 5.5 to 6.5.
• Record Keeping: Document the germination process to qualify for the three-month germination guarantee.

Once sprouted, plant the seeds with the tap root facing down in soil, keeping it consistently moist. Growth can take up to two weeks before visible development occurs.

Cultivation Tips

To maximize yield and preserve the grape-like flavor of Granddaddy Purple Auto, use a quality substrate such as perlite, peat, or coco coir. Growers have reported increased yields by up to 20% using these methods.

Autoflower strains like Granddaddy Purple Auto require minimal light—only 12 hours per day—to thrive and flower. However, for optimal results, we recommend a light cycle of 18/6 or 20/4.
