1. Germination & Early Seedling Stage (Days 1–10)
- Germination Method: Paper towel or direct sow in starter cubes.
- Environment: Keep temps around 22–26°C (72–79°F), with RH 65–70%.
- Lighting: Use a gentle LED light (~100–150 PPFD).
- Watering: Keep soil slightly moist—not wet. Use a spray bottle to avoid overwatering.
Tip: Avoid transplanting if possible. Autoflowers like Zkittlez prefer to stay in their final container from the start (3–5 gal pots recommended).
2. Vegetative Stage (Days 11–25)
- Light Cycle: 18/6 or 20/4 (autoflowers don’t require 12/12).
- Light Intensity: Increase to 300–400 PPFD.
- Nutrients:
- Start feeding light veg nutrients (N-rich).
- Supplement with CalMag—Zkittlez is cal/mag hungry.
- Environment:
- Temp: 22–26°C (72–79°F)
- RH: 55–65%
Tip: Watch for rapid vertical growth when learning how to grow Zkittlez as she stretches and creates large internodes, making it ideal for LST (Low-Stress Training) to spread canopy and increase bud size.
3. Flowering Stage (Days 26–65)
- Pre-Flower (Days 26–35):
- Transition to bloom nutrients (P and K-heavy).
- Lower RH to 45–55% to prevent mold.
- Increase light intensity to 500–600 PPFD.
- Aroma will begin to intensify—start odor control early.
- Full Flower (Days 36–60):
- Buds fatten quickly—main cola forms iconic triangle/crown shape.
- Keep feeding bloom nutes + CalMag.
- Monitor for deficiencies—this strain uses nutrients aggressively.
- Late Flower / Flush (Days 61–65):
- Begin flush with plain water 7–10 days before harvest.
- Trichomes should be mostly cloudy with some amber for optimal potency.
- Aroma shifts from chocolate notes to sweet, berry-candy fragrance.
Tip: Use support stakes if needed—Zkittlez can get top-heavy with massive colas.
4. Harvest & Post-Harvest
- Harvest Time: Around Week 9 (Day 63–65).
- Yield: Up to 300g per plant with optimal conditions.
- Drying:
- 60°F (15°C) / 60% RH for 7–10 days in darkness.
- Trim after drying (dry trim recommended for frost preservation).
- Curing:
- Cure in glass jars for 2–4 weeks to enhance candy-like terpene profile.
- Burp jars daily during week 1, then taper off.

- Soil: 6.0–6.5
