Pre-flowering Stage

Conditions

What Are the Ideal Conditions During the Pre-Flowering Stage?

Creating the right environment during pre-flowering helps plants adjust smoothly to the flowering stage.

Expectations

What Can You Expect During the Pre-Flowering Stage?

• Plants stretch significantly (can double in size).
• The first signs of sex appear (white pistils for females, pollen sacs for males).
• Bud sites begin to form along branches.
• Growth slows as the plant transitions to full flowering.

Methods

Are There Different Methods for the Pre-Flowering Stage?

Growers often use low-stress training (LST), topping, or SCROG to manage height and maximize light exposure. Some reduce nitrogen intake earlier to prepare for flowering.

Troubleshooting

What Problems Can I Encounter During the Pre-Flowering Stage?

• Overstretching - Caused by weak lighting or excessive nitrogen.
• Hermaphroditism - Stress factors like light leaks or temperature fluctuations may trigger male traits.
• Nutrient deficiencies - A lack of phosphorus or potassium can delay bud formation.
• Pests & mold - Increased foliage can attract pests and hold excess moisture.

Duration

How Long Does the Pre-Flowering Stage Take?

The pre-flowering stage lasts 1-3 weeks, depending on the strain and growing conditions. Photoperiod plants require a 12/12 light cycle to continue into full flowering.
