Setting Up The Growing Cannabis Space

Before you start growing this Auto, ensure you have an efficient and well-organized growing space. Whether you choose indoor or outdoor cultivation, consider the following factors:

Indoor Cannabis Cultivation

For indoor growers, selecting the right grow tent or dedicated grow room is crucial. Ensure the space provides sufficient vertical room for the plants to grow and proper ventilation for fresh airflow. Install an efficient exhaust system with a carbon filter to control odors and prevent heat or humidity buildup. Use reflective materials or Mylar sheets to maximize light distribution and prevent light leaks that could disrupt the flowering phase.

Choose a suitable growing medium for Granddaddy Purple Auto, such as high-quality soil or a hydroponic system, depending on your preferences and experience. Ensure proper drainage to prevent waterlogging and maintain a balanced pH level of around 6.0-6.5 for optimal nutrient absorption.

Successful germination and propagation are essential for healthy and vigorous Granddaddy Purple Auto plants. Follow these steps to ensure a high germination rate and successful propagation:

1. Start by selecting high-quality Granddaddy Purple Auto seeds from a reputable seed bank. This ensures genetic stability and the feminization of your plants.

2. Begin the germination process by soaking the seeds in distilled water or a damp paper towel for 24-48 hours. Maintain a temperature between 70-85°F (21-29°C) and provide a dark and undisturbed environment.

3. After the seeds have soaked and developed taproots, transfer them carefully to a pre-moistened growing medium, such as a seedling tray or small pots filled with a light and well-draining soil mix.

4. Place the seeds in a warm and humid environment with gentle airflow. Maintain a temperature around 75-80°F (24-27°C) and a humidity level of 60-70% for optimal germination.

5. Provide indirect light to the seedlings during the first few days, gradually increasing the light intensity as they develop. Avoid exposing them to intense light or heat that could cause stress or damage.

Monitor the plants closely and adjust nutrient levels as needed to avoid deficiencies or toxicities.

Temperature and Humidity: Maintain a slightly lower temperature during the flowering phase, ideally around 65-75°F (18-24°C), to encourage resin production and prevent heat-related stress. As for humidity, aim for levels around 40-50% to minimize the risk of mold or bud rot.

Support: As your Granddaddy Purple Auto plants enter the flowering phase, the weight of the developing buds may cause branches to bend or break. Provide adequate support using stakes or trellises to ensure the plants can bear the weight and avoid bud damage.

Flowering Time: Granddaddy Purple Autoflower typically has a flowering time of 8-10 weeks, but this can vary depending on the specific phenotype and environmental conditions. Monitor the trichome development using a magnifying tool to determine the optimal harvest window.

Choosing the Right Fertilizer: Select a high-quality cannabis-specific fertilizer or nutrient line that provides a balanced blend of macro and micronutrients. Look for products rich in nitrogen (N), phosphorus (P), and potassium (K) to support healthy growth, root development, and bud formation.

Feeding Schedule: Follow the manufacturer’s instructions and adjust the feeding schedule based on your plants’ specific needs. Start with a lower concentration and gradually increase it as the plants progress through their growth stages. Monitor the plants closely for any signs of nutrient deficiencies or excesses and make adjustments accordingly.

Supplements and Additives: Consider incorporating supplements and additives into your feeding regimen to enhance specific aspects of plant development. These may include bloom boosters, beneficial microbes, enzymes, or organic amendments that improve soil structure and nutrient availability.

Harvesting and Curing for Cannabis Growing – Granddaddy Purple Auto

Harvesting your Granddaddy Purple Auto at the right time and properly curing

them are crucial steps in achieving top-quality buds with the desired potency, flavor, and aroma. Here’s how to go about harvesting and curing this Auto cannabis plants:


Harvesting your Granddaddy Purple Auto cannabis plants at the optimal time ensures the best results. Look for the following signs to determine when to harvest:

  • Trichome Color: Examine the trichomes on the buds using a magnifying tool. Harvest when the majority of trichomes have turned milky white or cloudy. If you desire a more relaxing effect, wait for some amber trichomes to develop, but avoid letting them turn entirely amber.
  • Bud Structure: Check the buds for fullness and density. They should feel firm and swollen, indicating maturity. Avoid harvesting prematurely when the buds are still airy and undeveloped.
  • Pistil Color: Observe the color of the pistils (hairs) on the buds. Most strains, including this Auto, have pistils that change from white to reddish-brown as they mature. Harvest when a significant portion of the pistils has turned brown.

Use sharp, clean pruning shears or scissors to carefully trim the buds from the branches, leaving a small stem attached to each bud. Handle the buds gently to avoid damaging the trichomes.


Curing is the process of drying and aging your harvested buds to enhance their flavor, aroma, and overall quality. Follow these steps for a successful curing process:

  • Trimming: After harvesting, trim away any excess leaves and stems from the buds. This improves airflow during the curing process and enhances the appearance of the final product.
  • Drying: Hang the trimmed buds in a dark and well-ventilated space with a temperature of around 60-70°F (15-21°C) and a humidity level of 45-55%. Use a drying rack or strings to hang the buds upside down. Allow them to dry for 7-10 days, depending on humidity levels and bud size. Buds are ready for the next phase when the stems snap rather than bend.
  • Curing Containers: Once the buds have dried to the appropriate moisture content, transfer them to airtight glass jars or containers. Fill the containers to about 75% capacity to leave room for air circulation.
  • Burping: During the curing process, open the containers daily for the first week to release built-up moisture and gases. This step is crucial for preventing mold growth. Gradually reduce the frequency to once every few days, then weekly, as the curing process progresses.
  • Curing Duration: Granddaddy Purple Auto benefits from a longer curing period. Aim for a minimum of 4-6 weeks of curing to achieve the best flavor and aroma. Some growers even choose to cure for several months to further enhance the qualities of their buds.

Properly cured those  Auto buds will have a smoother smoke, a more pronounced flavor profile, and a well-preserved terpene profile. Ensure the curing containers are stored in a cool, dark place away from direct light and heat.
