How It Works
Two ways to fruit:
- For Antlers: Keep the grow bag sealed to maintain high CO2 levels, encouraging long, antler-like structures. Ensure indirect light, warm temperatures (21-27°C) and minimal airflow.
- For Conks: Fully open the grow bag or make large slits to allow fresh air, reducing CO2 and promoting flat, fan-like growths with red and white bands. Place the block in a well-ventilated area, with indirect light, warmth (21-27°C), and regular misting to keep humidity high.
