| Factor | Range |
|---|---|
| Temperature | 70–85°F (21–29°C) |
| Humidity (veg) | 50–60% |
| Humidity (flower) | 40–45% |
| Light | 18/6 veg, 12/12 flower |

Cooler nighttime temps (below 65°F) during flowering will help bring out the vivid purple hues that Purple Urkle is famous for.
6. Germination Tips for Purple Urkle Seeds
Starting strong is key to a successful grow.
Germination Steps:
- Soak seeds in distilled water for 12–18 hours.
- Transfer to moist paper towel, fold gently.
- Place in a ziplock bag or between plates.
- Store in a dark, warm place (75–85°F).
- Check daily for sprouting (usually within 2–4 days).
- Transplant once root emerges (~1 cm long).
7. Seedling and Vegetative Stage Tips
Once your Purple Urkle seedling sprouts its first true leaves, it enters the veg stage.
Key Tips:
- Use a low-nitrogen seedling soil or light mix.
- Keep humidity around 60% in early veg.
- Provide 18–24 hours of light per day.
- Avoid overwatering. Let the top 1″ of soil dry out before watering.
- Begin low-dose nutrients (N-rich) around week 2–3.
Watch for tight internodal spacing, a sign of healthy Urkle veg growth.
8. Training Techniques for Bigger Yields
Because Purple Urkle tends to grow bushy, it’s ideal for training to maximize light exposure.
Recommended Techniques:
- Topping: Increases lateral growth for more colas.
- LST (Low Stress Training): Gently bend and tie branches.
- ScrOG (Screen of Green): Train under a net for even canopy.
- Defoliation: Remove large fan leaves that block bud sites.
Proper training during veg leads to denser buds and higher yields in flower.
9. Flowering Stage: When Purple Urkle Shows Her Colors
Purple Urkle’s flowering stage is visually stunning. Expect deep purple buds, fiery orange pistils, and thick layers of frost.
Signs of Flowering:
- Pistils (white hairs) begin to form.
- Buds swell noticeably by week 4–5.
- Trichomes start to develop rapidly.
Flowering Timeline:
| Week | What Happens |
|---|---|
| 1–2 | Flower initiation, stretch begins |
| 3–5 | Buds form, trichomes begin |
| 6–8 | Buds swell, color intensifies |
| 9–10 | Trichomes mature, pistils darken |
Pro tip: Lower night temps (60–65°F) can enhance purple coloration.
10. Nutrients, Feeding, and pH for Purple Urkle
Purple Urkle responds well to a balanced feeding schedule but is sensitive to overfeeding.
Veg Stage:
- Nutrients: High nitrogen (N), moderate phosphorus (P), moderate potassium (K)
- Example Ratio: 4-2-3
Flowering Stage:
- Nutrients: Low nitrogen, high phosphorus and potassium
- Example Ratio: 1-4-5
Additional Tips:
- Use Cal-Mag during veg and early flower.
- Flush 10–14 days before harvest.
- Monitor pH closely to avoid nutrient lockout.
11. Indoor vs. Outdoor Growing Tips
Indoor Growing:
- Use full-spectrum LED or HPS lights.
- Maintain tight control over temperature and RH.
- Employ training (ScrOG or LST) for even canopy.
- Expect yields of 400–500g/m².
Outdoor Growing:
- Choose a sunny, dry area with ample airflow.
- Plant after the last frost.
- Harvest in late September to early October.
- Yields can exceed 600g per plant in optimal conditions.
12. Harvesting Purple Urkle: When to Cut
Knowing when to harvest is crucial to capture Urkle’s potency and flavor.
Signs of Readiness:
- 70–90% of pistils have darkened.
- Trichomes are mostly cloudy with some amber.
- Buds are firm, sticky, and aromatic.
Use a jewelers loupe to inspect trichomes. Cloudy trichomes = peak THC. Amber = more sedative effect.
13. Drying and Curing Purple Urkle Buds
Once harvested, proper drying and curing is essential for taste, potency, and smoothness.
Drying:
- Hang branches in a dark room at 60–70°F with 50% RH.
- Dry for 7–10 days, or until small stems snap.
Curing:
- Trim buds and place in glass jars.
- Store in a cool, dark place.
- Open jars daily for 10–15 minutes (“burping”) for 2 weeks.
- Cure for 3–6 weeks total.
Properly cured Purple Urkle will smell like grapes, berries, and skunk, with smooth, potent smoke.
14. Common Growing Issues and How to Avoid Them
🌿 Bud Rot:
- Caused by high humidity.
- Use fans, dehumidifiers, and proper spacing.
🌿 Nutrient Burn:
- Symptoms: Yellow/brown leaf tips.
- Solution: Flush and reduce feeding.
🌿 pH Imbalance:
- Leads to nutrient lockout.
- Keep soil pH between 6.0–6.5.
🌿 Mold:
- Urkle’s dense buds are mold-prone late in flower.
- Ensure airflow and humidity control.
