How to Grow Granddaddy Purple Seeds?

Cultivating Granddaddy purple is the best way to ensure you get just the right potencies and effects in your yield. We take a look at how to get the best and biggest harvests.

Indoor Growing

Indoor growers need to create the ideal environmental conditions for Granddaddy Purple seeds to grow into healthy plants with bigger yields, and this includes the correct lighting, temperature, and humidity.

They flourish in daytime temperatures that range between 68°F to 78°F (20°C to 25°C, which should be cooler at night to bring out the natural purple color. 

Humidity levels should be kept at around 50% during the vegetative and 40% during the flowering stage to prevent the growth of mold on the buds.

To further prevent mold and disease and promote the rapid growth of healthy, high-quality buds, the trees should be kept well-ventilated with fresh airflow and pruned regularly. Watering needs to be done lightly to prevent waterlogging and poor nutrient absorption.

Nutrient-rich soil with excellent drainage is another essential factor for successful cultivation. You should use a nitrogen-focused nutrient blend for vegetative growth and then switch to phosphorus and potassium-rich fertilizers during the flowering phase to boost the yield.

If you follow these practices and your plants are well cared for, you can expect to reach the flowering time much faster with yields of up to 500 grams per square meter.

Outdoor Growing

Outdoor growers have to deal with a completely different can of worms when it comes to cultivating Granddaddy Purple. It does well in warm, dry Mediterranean-like climates. So, it is important to plant them in a sunny spot that receives long hours of sunshine.

The kind of soil you use is also important, and this should have good drainage and be rich in organic nutrients. A solid PH of between 6.0 and 7.0 will help the trees to better absorb nutrients. Make sure to compensate for dry and warm weather with sufficient watering. 

With care and consistent effort, outdoor growers can expect big harvests, ranging between 500 to 700 grams per plant.
