Suver Haze

Cannabis sativa L.

herb

Suver Haze is a high-CBD hemp cultivar known for its balanced cannabinoid profile and floral, sweet aroma. This sativa-dominant strain produces dense flowers rich in cannabidiol (CBD) with minimal THC content, making it legally compliant in most jurisdictions. It is prized by hemp farmers for both its therapeutic cannabinoid content and its resilience to pests and environmental stress.

📏
Spacing: 36-48 inches
📅
Days to maturity: 90-120
🌱
Planting depth: 0.5-1 inch

Soil

Type: Well-draining loamy soil with moderate fertility
pH: 6.0-7.0
Amendments:
Compost or aged manure Perlite or coarse sand for drainage Balanced NPK fertilizer (e.g., 10-10-10) Mycorrhizal fungi inoculant

Growth Stages

1

Seedling

2-3 weeks

Cotyledons emerge with a pair of rounded seed leaves; true leaves develop within 7-10 days. Plant is delicate and pale green.

Keep soil moist but not saturated. Provide 16-18 hours of light daily. Maintain 70-75°F temperature. Protect from wind and direct heat.

2

Vegetative

4-8 weeks

Rapid stem elongation and leaf development. Plant develops multiple branches and deep green coloration. Robust root system establishes.

Maintain 16-18 hours of light and 12-14 hours darkness (outdoor). Apply balanced nitrogen-rich fertilizer every 2-3 weeks. Ensure adequate spacing for air circulation. Prune lower branches if desired to encourage upward growth.

3

Flowering Initiation

2-3 weeks

Plant transitions to 12-hour light/dark cycle (late summer outdoors). Preflowers appear at branch nodes; plant architecture becomes more compact and bushy.

Reduce nitrogen; shift to phosphorus and potassium-rich fertilizer. Monitor for male flowers (sacs) if growing for sensimilla. Increase potassium and phosphorus for resin production.

4

Flowering & Bud Development

6-8 weeks

Dense flower clusters (buds) form with visible resinous trichomes. Suver Haze develops characteristic sweet, floral aroma. Flowers become increasingly potent.

Continue P-K dominant fertilizer. Monitor humidity (45-55%) to prevent powdery mildew. Scout for spider mites and aphids daily. Do not overwater. Support heavy branches if needed.

5

Harvest Ready

1-2 weeks (pre-harvest window)

Trichomes turn milky white with some amber. Flowers are dense, aromatic, and resin-coated. Leaves begin to yellow slightly.

Flush soil with plain water 1-2 weeks before harvest to remove excess nutrients. Cut at peak trichome development (mostly cloudy, <10% amber). Dry slowly at 60-65°F, 45-55% RH for 7-10 days.

Companion Planting

Plan your garden →

Plant with:

Clover (nitrogen fixation) Borage (pest control, pollinator support) Marigold (pest deterrent) Dill (beneficial insect attraction) Chamomile (fungal disease prevention)

Avoid planting near:

Male hemp or cannabis plants (if growing for sensimilla) Fennel (allelopathic; inhibits hemp growth) Brassicas in very close proximity (compete for nutrients)

Common Pests

  • Spray with neem oil or insecticidal soap every 3-4 days. Maintain humidity above 50%. Introduce predatory mites (Phytoseiulus persimilis). Remove heavily infested leaves.

  • Reduce humidity to 40-50%; improve air circulation with fans. Apply sulfur dust or potassium bicarbonate fungicide. Remove infected leaves. Avoid overhead watering.

  • Strong water spray to dislodge. Spray with insecticidal soap or neem oil. Release ladybugs or parasitic wasps. Reflective mulches can deter colonization.

  • Hand-pick if population is small. Apply Bt (Bacillus thuringiensis) spray. Use pheromone traps to monitor. Remove damaged buds immediately.

  • Spray with sulfur or insecticidal soap at first sign. Increase humidity slightly (but not >60%). Remove heavily infested plant material. Consider predatory mites.

Uses

💊

CBD Wellness & Pain Relief

Medicinal

Suver Haze flowers are rich in cannabidiol (CBD), a non-intoxicating cannabinoid studied for analgesic, anti-inflammatory, and anxiolytic properties. Users consume it as flower, oil extract, or infusions for chronic pain management and stress relief. [source]

🍳

CBD-Infused Edibles & Teas

Culinary

Dried flower and leaves can be steeped in hot water for herbal tea or infused into oils, butter, and honey for culinary applications. The sweet, floral flavor complements desserts and beverages. [source]

🎨

Biomass & Extraction

Craft

Suver Haze is a popular cultivar for commercial CBD extraction. Its high cannabinoid density and favorable terpene profile make it ideal for concentrates, distillates, and isolates. [source]

🏠

Aroma & Household Use

Household

Dried flowers retain a pleasant sweet and floral scent. They are used as potpourri, in aromatherapy diffusers, or as a natural room freshener. [source]

💊

Sleep & Relaxation Support

Harvest Tips

Harvest when 60-80% of trichomes are milky white with 10-20% amber; this indicates peak CBD content. Cut entire plant at soil level or harvest individual branches. Dry in darkness at 60-65°F with 45-55% relative humidity for 7-10 days. Cure in glass jars at 62°F and 62% RH for 2-4 weeks, burping jars daily to release moisture. Proper drying and curing maximizes terpene retention and CBD stability.

Fun Facts

  • 🌱 Suver Haze was one of the first certified high-CBD hemp cultivars released after the 2018 Farm Bill legalized hemp cultivation in the United States, becoming a cornerstone variety for the CBD industry.
  • 🌱 The name 'Haze' references the legendary Haze genetics from the 1970s-80s cannabis breeding era; Suver Haze inherited the resilience and vigor of these lines while adding CBD-dominant expression.
  • 🌱 Suver Haze can produce over 10% CBD by dry weight under optimal growing conditions, while maintaining THC levels well below 0.3%, making it legally compliant for hemp production in most regulated markets.
