Super Jack Feminized Seeds

Q: When should I harvest Super Jack?

Monitor trichomes. Harvest when about 20-30% of trichome heads turn amber and most remain cloudy for balanced potency and aroma.

Q: How should I train plants to control stretch?

Start low-stress training early and add topping after 3-4 nodes. Use SCROG or mainline to flatten the canopy and limit vertical growth.

Q: What feeding schedule suits Super Jack?

Use moderate veg nutrients at 400-600 ppm. Increase to 800-1200 ppm in flower while watching leaf color and tip condition.

Q: How to improve terpene expression?

Lower night temperatures in late flower to 16-18 C and dry slowly at 10-12% humidity to preserve citrus and pine terpenes.

Q: Does Super Jack need heavy pruning?

Perform selective defoliation early and avoid heavy pruning in the last two weeks of flower to protect buds and trichomes.

Q: What pests present the biggest risk?

Spider mites and aphids are common issues. Keep humidity stable, inspect leaves weekly, and apply targeted treatments at first sighting.

Q: Is Super Jack suitable for extracts?

High resin production from Haze and Jack genetics yields quality rosin and solvent extracts when using proper drying and curing.

Q: How to avoid nutrient burn?

Start feeds at lower strength and increase gradually. Flush with plain water for several feed cycles if tip burn appears.

Q: What light intensity works best?

Provide strong light during veg and flower. Aim for 600-1000 µmol/m2/s at canopy in flower for dense bud development.

Q: Is Super Jack beginner friendly?

Suitable for growers with basic training experience. Beginners should learn topping, LST, and feed management before the first full run.
