Black Ube Feminized Seeds

Q: What feeding schedule works for Black Ube?

Start at half strength for seedlings, ramp to full strength in vegetative stage, then reduce during weeks six to eight of flower to avoid nutrient lock.

Q: When should I flush before harvest?

Begin a water-only flush seven to ten days before harvest to improve smoke and reduce excess nutrients.

Q: How do I encourage purple coloration?

Lower night temperatures by 6 to 10 degrees Celsius in late flower and maintain strong but safe phosphorus and potassium levels.

Q: What training methods suit this strain?

Use topping early and LST or SCROG to spread canopy and increase bud sites for higher yields.

Q: How do I prevent bud rot?

Keep humidity under 50 percent in late flower, increase airflow across colas, and remove dense interior foliage.

Q: What lighting works best indoors?

Full-spectrum LEDs at 40 to 60 watts per square foot produce dense buds and good terpene retention.

Q: When is peak harvest window?

Check trichomes; harvest when many trichomes turn cloudy with some amber for balanced effects.

Q: Does Black Ube stretch in flower?

Expect moderate stretch in the first two weeks of flower; finish main training before flip to 12/12.

Q: Which nutrients to emphasize in flower?

Increase phosphorus and potassium during weeks four to eight while keeping nitrogen moderate.

Q: How long should cured buds be stored?

Cure for four to eight weeks in glass jars and store in a cool, dark place for up to one year for best flavor.
