Papa’s OG thrives in moderately warm, stable environments with relatively low humidity in the flowering stage to prevent bud rot.
| Growth Phase | Day Temp (°C) | Night Temp (°C) | RH (%) | VPD (kPa) |
|---|---|---|---|---|
| Vegetative | 24–28 | 20–22 | 60–70 | 0.8–1.1 |
| Flowering | 21–26 | 18–21 | 40–50 | 1.2–1.5 |
| Ripening | 20–24 | 16–18 | 35–45 | 1.3–1.6 |
Scientific insight: Proper control of Vapor Pressure Deficit (VPD) during flowering is crucial for stomatal function, nutrient uptake, and resin gland formation.
B. Lighting Conditions
Papa’s OG, as an indica hybrid, benefits from intense, well-balanced lighting to encourage dense bud formation and maximum trichome development.
| Stage | PPFD (µmol/m²/s) | Photoperiod | Light Spectrum Focus |
|---|---|---|---|
| Vegetative | 400–600 | 18/6 | Blue-heavy (~450 nm) |
| Flowering | 700–900 | 12/12 | Red-rich (~660 nm), UV-B (280–315 nm) |
| Late Flower | 800–1000 | 12/12 or 10/14 | Full + UV-B (for 2–3 hours/day) |
UV-B exposure during weeks 6–8 enhances trichome density and THC synthesis by mimicking high-altitude light stress.
III. Medium, Root Health, and Irrigation
A. Preferred Growing Media
| Medium Type | Characteristics |
|---|---|
| Soil (organic) | Terpene-rich, buffered nutrient release |
| Coco Coir + Perlite (70:30) | Fast growth, high oxygenation, but needs Ca/Mg supplementation |
| Hydroponics | Rapid growth and high control, but low terpene complexity if not managed carefully |
Soil and coco blends are most popular with Papa’s OG for preserving flavor, aroma, and secondary metabolite development.
B. Root Zone Parameters
| Medium | Target pH | Target EC (Veg) | Target EC (Flower) |
|---|---|---|---|
| Soil | 6.2–6.8 | 1.2–1.6 | 1.8–2.2 |
| Coco | 5.8–6.2 | 1.5–1.8 | 2.0–2.4 |
Use mycorrhizal fungi inoculants to boost nutrient uptake, especially phosphorus and micronutrients, which are critical in the flowering phase.
IV. Nutrient Management
Papa’s OG has moderate nutrient demands with a strong focus on potassium, phosphorus, and magnesium during flowering.
A. Macronutrient Strategy (NPK)
| Stage | Nitrogen (N) | Phosphorus (P) | Potassium (K) | Notes |
|---|---|---|---|---|
| Vegetative | High | Medium | High | Leaf, stem, and root expansion |
| Early Flower | Medium | High | High | Supports bud initiation |
| Late Flower | Low | High | Very High | Maximizes resin production |
Reduce nitrogen after week 4 of flower to prevent excess leaf growth and promote dense bud formation.
B. Micronutrient Focus
- Calcium: Required for cell wall integrity in developing colas.
- Magnesium: Central to chlorophyll synthesis and terpene biosynthesis.
- Sulfur: Crucial for thiol-based terpenes and enzyme function.

| SCROG | Equalizes canopy height, prevents shade | Transition to flower |
| Defoliation | Reduces humidity, improves light flow | Early–mid flower |
Avoid over-defoliation in flower, which can stress the plant and reduce yield.
VI. Flowering and Ripening Dynamics
A. Flowering Timeline
| Week | Developmental Milestone |
|---|---|
| 1–2 | Flower set; stretch slows |
| 3–5 | Trichomes and bud mass increase rapidly |
| 6–8 | Peak resin production; aroma intensifies |
| 9+ | Optional extended ripening (for amber trichomes) |
B. Maturation Indicators
- Trichomes: 90% cloudy, 10–30% amber (for sedative effects)
- Pistils: 80–90% orange/brown
- Aroma: Pungent sweet fuel and earth tones at peak
VII. Harvest, Drying, and Curing
A. Drying Protocol
| Condition | Ideal Range |
|---|---|
| Temperature | 60–65°F (15–18°C) |
| Humidity | 50–60% RH |
| Duration | 10–14 days |
| Airflow | Gentle, indirect |
Slow drying preserves terpenes like myrcene, limonene, and linalool, which are volatile and degrade at high temps.
B. Curing Strategy
- Cure in glass jars at 62% RH using humidity packs.
- Open jars (burp) 1–2 times daily for first 2 weeks.
- Minimum cure time: 4 weeks (6–8 weeks ideal for flavor and smoothness).
Extended curing improves aroma complexity, combustion quality, and terpene stability.
VIII. Yield and Quality Optimization
Resin and Terpene Enhancement Techniques
- UV-B Exposure (2–3 hours/day during weeks 6–8)
- Sulfur and magnesium supplementation during mid-flower
- Low night temperatures (16–18°C) in final 2 weeks for anthocyanin expression and volatile retention
- Carbohydrate boosts (e.g., molasses, amino acid additives) for microbial and terpene activity
Avoid stress during late flowering (e.g., overwatering, pH swings), which can cause hermaphroditism or reduced oil production.
IX. Pest and Pathogen Prevention
Due to its dense buds, Papa’s OG is susceptible to mold and pests if air circulation is poor.
| Threat | Prevention Strategy |
|---|---|
| Bud Rot (Botrytis) | Maintain <50% RH, strong airflow |
