Growing Conditions & Tips

• Climate: Thrives in moderately humid conditions with temperatures between 70–80°F (21–27°C); proper ventilation is important to prevent mold and mildew.
• Suitable for: Indoor or outdoor growing — adapts well to Mediterranean or sunny climates outdoors.
• Training: Low-Stress Training (LST) improves light penetration and promotes larger buds, especially indoors.
• Nutrients: Nutrient-rich feed in veg, switching to bloom-specific nutrients at flowering.

Harvesting

Monitor trichomes closely — harvest when most are cloudy with a few amber for a calming, well-rounded result. A slow dry and a proper cure help preserve the berry-grape aroma and deep purple color; see our guide to drying vs. curing marijuana.
