White Rainbow Feminized Seeds

Q: What light schedule works in veg and flower?

Use 18/6 for vegetative stage and switch to 12/12 for flowering. Aim 500 to 700 μmol/m²/s during bloom.

Q: What nutrient ppm levels do you use?

Start veg at 400 to 600 ppm. Raise to 800 to 1000 ppm in early flower. Peak around 1000 to 1200 ppm in mid flower.

Q: How do you prevent stretch after flip?

Tighten canopy before flip with topping and LST. Keep night temps 18 to 20°C to limit excessive stretch.

Q: When is optimal harvest window?

Harvest when most trichomes are milky and amber reaches 20 to 30 percent. Check multiple bud sites for consistency.

Q: What humidity for flowering?

Hold relative humidity at 40 to 50 percent in early bloom. Drop to 35 to 45 percent late bloom to reduce mold risk.

Q: How long to cure buds?

Dry to 10 to 12 percent moisture, then cure in sealed jars 2 to 4 weeks minimum. Aim 4 to 8 weeks for fuller flavor.

Q: Which training suits this strain?

Topping at 3 to 4 nodes followed by SCROG or LST yields even canopy and bigger colas.

Q: How do you handle nutrient burn?

Reduce EC by 0.2 to 0.5 mS, flush with pH-balanced water, then resume at 75 percent strength.

Q: What pest prevention steps work?

Keep intake air filtered, run steady airflow across canopy, inspect weekly, and treat early with biological controls.

Q: How to avoid bud rot outdoors?

Plant in a spot with good sun and afternoon breeze, prune lower growth for airflow, and harvest before persistent rain.
