Cuban Black Haze Feminized Seeds

Q: What soil pH should you aim for?

Keep soil pH between 6.0 and 6.8 for optimal nutrient uptake.

Q: Which training methods work best?

Use SCROG or low stress training to manage vertical stretch and increase bud sites.

Q: How often should you feed during flowering?

Increase bloom nutrients gradually and monitor leaf tips for burn. Adjust every 7 to 10 days.

Q: How do you control stretch in week 3 to 5?

Apply topping and LST early, then use a screen to spread the canopy before heavy stretch.

Q: What humidity levels are ideal during flowering?

Keep relative humidity between 40% and 50% to reduce mold risk and preserve terpenes.

Q: When should you flush before harvest?

Begin a mild flush 7 to 10 days before planned harvest to improve smoke quality.

Q: How do you identify peak ripeness?

Watch trichomes with a loupe: aim for mostly cloudy with some amber for balanced effects.

Q: Does this strain like heavy feeding?

Moderate feeding works best. Overfeeding causes nutrient lockout and slows growth.

Q: What pests pose the biggest threat?

Spider mites and powdery mildew are common threats in warm, humid setups. Inspect leaves weekly.

Q: How should you cure the harvest?

Dry slowly at 45% to 55% humidity, then cure in jars with daily burps for the first two weeks.
