• Carefully controlled moisture levels
• Stable temperature range (20-25°C)
• Moderate humidity (70-80%)

Precision in early plant care determines the future vigour and productivity of cannabis plants.

Growers must be extremely careful during the seedling stage. The young plant’s root system is still fragile. Overwatering is a major risk that can stunt growth or harm roots.

Growth Parameter	Optimal Range
Duration	1-3 weeks
Temperature	20-25°C
Humidity	70-80%
Light Cycle	18-24 hours

Grasping these detailed needs ensures strong cannabis seedling growth. This sets the stage for healthy vegetative growth and flowering later on.

How Long for Cannabis Seeds to Mature
