Grapefruit Durban Feminized Seeds

Q: How do I control height indoors?

Use topping and low stress training early. Switch to 12/12 only after you limit stretch. Build support for tall colas.

Q: What light schedule works best?

Use 18/6 for veg and 12/12 for flower. Increase light intensity during bloom to boost resin and terpene output.

Q: Which nutrients are critical in flower?

Increase phosphorus and potassium during weeks 3 to 6 of bloom. Keep nitrogen moderate to avoid excessive leaf growth.

Q: How do I manage humidity in late flower?

Drop relative humidity to 40 to 45 percent during the final two weeks. Use fans and dehumidifiers to prevent mold on dense colas.

Q: When is the best time to harvest?

Harvest when trichomes show a mix of cloudy and 10 to 20 percent amber for energetic, slightly rounded effects.

Q: How should I cure buds?

Dry slowly at 50 percent humidity for 7 to 10 days, then jar at 60 to 62 percent humidity. Burp daily for two weeks.

Q: Are pests a big risk?

Warm, dry climates reduce fungal issues but spider mites and thrips will target plants. Scout weekly and treat early with biologicals.

Q: What training methods work best?

SCROG and LST work well to manage stretch and even the canopy. Top once or twice for better lateral growth.

Q: How do I preserve the citrus terpene profile?

Avoid over-flushing and high-heat drying. Keep harvest handling minimal and cure slowly to retain fresh grapefruit notes.

Q: What pot size should I use outdoors?

Use 20 to 40 liter pots for a single outdoor plant to allow deep root development and higher yields.

Q: My plants stretch too much after flip. How do I limit that?

A: Top before the flip and apply low stress training to spread the canopy. Delay flip until plants are shorter if space allows.
