How to Grow White Widow Autoflower CBD Strain

White Widow Autoflower CBD Description

White Widow Autoflower CBD is a mostly-Indica (60% Indica / 40% Sativa) fast-flowering hybrid bred from a High-CBD line crossed with White Widow. It offers low THC (8%–9%) and medium CBD (9%–10%), delivering a strong, relaxing body high with gentle cerebral uplift. Ideal for beginners, this autoflower finishes in 8–10 weeks and reaches about 4.92 ft (1.5 m).

Yields are high: indoors 1.31–1.64 oz/ft² (400–500 g/m²) and outdoors 17–19 oz/plant (500–550 g). Dense buds exude citrus, herbal, and lemon aromas, driven by terpenes like Alpha-Pinene, Beta-Caryophyllene, Caryophyllene, Guaiol, Humulene, Isopulegol, and Neryl-acetate.

Medicinally, it helps fatigue (CB1/CB2 balance), muscle spasms (Myrcene & Humulene), and stress (Limonene). Users report creative, energetic, and uplifted effects alongside deep relaxation.

Growing Environment

Indoors, maintain 70–78°F (21–25°C) day temperatures and 5°F cooler at night. During veg, keep humidity at 60%–65%; drop to 40%–50% in flowering to prevent mold and enhance resin.

Outdoors, choose a sunny, sheltered spot with well-draining soil enriched with compost or worm castings. Ensure at least six hours of direct sun and protect from strong winds. In cooler climates, use a greenhouse to extend the season.

Good airflow is vital: use oscillating fans indoors and space outdoor plants 3 ft (1 m) apart to minimize disease pressure.

Setting Up Your Grow Space

White Widow Autoflower CBD Indoor Cultivation

Use a 4×4 ft tent with reflective Mylar. Hang full-spectrum LEDs on an 18/6 cycle in veg and maintain 20/4 for autos. Install a carbon-filtered exhaust and oscillating fans for temperature, humidity, and odor control.

Plant in 3–5 gal pots filled with an airy soil mix (pH 6.0–6.5) amended with perlite. Start directly in final pots to avoid transplant shock. Automate climate and light schedules with digital controllers.

White Widow Autoflower CBD Outdoor Cultivation

Mix native soil with compost and perlite in raised beds or fabric pots. Space plants 3–4 ft apart for airflow. Stake heavy branches early to support dense buds.

Water deeply when the top inch of soil dries, then allow slight drying between waterings. Mulch to conserve moisture and suppress weeds. Use shade cloth in heat waves and covers in heavy rain.

Seed Propagation and Germination

Soak seeds in distilled water for 12–24 h, then place between damp paper towels at 75–80°F (24–27°C). When taproots appear (24–48 h), plant taproot-down ½” into moist starter mix and cover with a humidity dome.

Provide 18–20 h of gentle light until true leaves form. Remove the dome over 3–4 days to acclimate seedlings. Mist lightly to maintain surface moisture without waterlogging.

White Widow Autoflower CBD Vegetative Phase

Maintain an 18/6 light schedule with lights 18–24″ above canopy. Feed a mild nitrogen-rich formula (N-P-K 3-1-2) at half strength weekly. Use low-stress training (LST) in weeks 2–3 to create an even canopy.

Keep 70–78°F and 60%–65% humidity. Introduce beneficial microbes or kelp extracts early to strengthen roots. Prune lower leaves to direct energy upward and improve airflow.

White Widow Autoflower CBD Flowering Phase

By week 4, flowering initiates automatically. Switch to a bloom formula high in phosphorus and potassium (N-P-K 1-3-2). Reduce humidity to 40%–50% and maintain 65–75°F to enhance resin and terpene production.

Remove large fan leaves around week 6 to expose bud sites. Support dense colas with soft ties. Begin flushing with plain water during the final week for smoother smoke.

Fertilization and Nutrition

Veg (weeks 1–4): N-P-K 3-1-2. Early bloom (weeks 5–7): N-P-K 1-3-2. Late bloom (weeks 8–10): N-P-K 0-3-3. Add calcium, magnesium, and micronutrients as needed. Flush in week 10.

Enhance soil with worm castings, bone meal, and kelp meal to support microbes and boost terpene profiles. A foliar seaweed spray early in bloom can improve bud set.

Pest & Disease Control

Inspect daily for spider mites, aphids, and thrips. At first sign, apply neem oil or insecticidal soap, covering leaf undersides. Use yellow sticky traps to monitor flying pests.

Maintain airflow to prevent powdery mildew and bud rot. Avoid overhead watering during flowering. Quarantine new plants 7 days before adding to the main grow.

White Widow Autoflower CBD Harvesting & Curing

Harvest when 70%–80% of trichomes are cloudy with some amber. Cut branches, trim fan leaves, and hang upside-down in a dark, ventilated room at 60–70°F and 50% RH for 7–10 days until stems snap.

Trim buds and jar loosely in glass jars up to 75% full. “Burp” jars 5–10 min daily in week 1, then weekly for 2–4 weeks. Use humidity packs to maintain 60%–62% RH.

Post-Harvest: Drying, Curing & Storage

After drying, trim final leaves and jar buds with humidity packs. Continue burping daily for one week, then weekly for 2–4 weeks to preserve terpenes.

Store jars in a cool, dark place at 60–65°F (15–18°C). Avoid light and temperature swings. For long-term storage, add desiccants or RH regulators.

Troubleshooting Common Issues

Nutrient Issues: Yellow leaves = nitrogen deficiency; burnt tips = nutrient burn. Correct by adjusting feed or flushing with pH-balanced water, then resume at half strength.

Environmental Stress: Heat causes leaf curl; light burn bleaches tips. Raise lights, improve ventilation, keep temps below 80°F, and maintain RH above 40%.

Watering & pH/EC: Overwatering droops; underwatering wilts. Water only when the top inch is dry. Keep pH 6.0–6.5 and EC 1.2–1.8 mS/cm.
