Cultivation of Grandmommy Purple
Growing Grandmommy Purple requires some expertise, but with the right techniques, cultivators can achieve impressive yields. This strain is suitable for both indoor and outdoor cultivation, though it thrives in controlled environments.
Growing Difficulty: Moderate
Climate: Grandmommy Purple prefers a warm, Mediterranean-like climate with consistent temperatures between 70-85°F (21-29°C). It’s essential to avoid excessive humidity to prevent mold growth.
Indoor Cultivation:
Controlling environmental factors is advantageous for indoor growers. This strain responds well to hydroponic setups or high-quality soil. The flowering time is approximately 8-10 weeks, with yields ranging from 400-500 grams per square meter.
- Lighting: During the vegetative stage, provide at least 18 hours of light per day. Change to a 12/12 light cycle while flowering.
- Humidity: During the vegetative stage, maintain humidity levels between 50 and 60 percent; during the flowering stage, lower them to 40 to 50 percent.
- Training Techniques: Low-Stress Training (LST) or topping can help maximize yields by promoting even canopy growth.
Outdoor Cultivation:
When grown outdoors, Grandmommy Purple requires plenty of sunlight and well-drained soil. Harvest typically occurs in late September to early October, with yields ranging from 500-600 grams per plant.
- Soil: Use nutrient-rich soil with proper drainage to ensure healthy root development.
- Watering: Steer clear of excessive watering as this may cause root rot. Water deeply but less frequently.
- Pest Control: Watch for common cannabis pests such as spider mites and aphids. Use natural repellents or integrated pest management techniques.
Color Enhancement:
The vibrant purple hues of Grandmommy Purple can be enhanced by exposing the plant to cooler temperatures during the late flowering stage. A drop to 55-65°F (13-18°C) at night can stimulate anthocyanin production, which is responsible for the purple coloration.
Harvesting and Post-Harvest Care

Harvesting:
To determine when Grandmommy Purple is ready for harvest, examine the trichomes using a magnifying glass or jeweler’s loupe. Harvesting is best done when the trichomes are mostly overcast with a few turning amber, indicating peak potency.
Drying:
Once harvested, hang the buds upside down in a dark, well-ventilated space that is between 60 and 70°F (15 and 21°C) and has a humidity of between 50 and 60%. Usually, this process takes seven to ten days.
Curing:
The buds should be cured in airtight glass jars after they have dried. For the first week, open the jars every day to get rid of extra moisture and avoid mold. The curing process enhances flavor and potency and typically lasts 2-4 weeks.
Tips for Consumption
Methods:
- Smoking: Ideal for those seeking immediate effects.
- Vaping: Offers a smoother experience and preserves more of the strain’s terpene profile.
- Edibles: For a longer-lasting and more intense high, incorporate Grandmommy Purple into homemade edibles. Be cautious with dosage due to its potency.
- Tinctures: Perfect for precise dosing and discreet consumption.
Dosage Recommendations:
- Beginner Users: Start with 1-2 puffs or 2.5 mg THC for edibles.
