Blue Donut Feminized Autoflowering Seeds

Q: What pot size works best?

Use 10 to 20 liter pots for outdoor plants. Indoor plants do well in 7 to 12 liter pots.

Q: Which training methods suit Blue Donut?

Use low stress training and light topping. SCROG works well to maximize canopy uniformity.

Q: What nutrient schedule should I follow?

Start with a balanced veg formula. Boost phosphorus and potassium in flower and reduce nitrogen after week 3 of bloom.

Q: How do I prevent bud rot?

Keep canopy airflow high. Remove dense inner growth and avoid late-season rain or prolonged humidity.

Q: What light schedule for indoor photoperiods?

Use 18/6 in veg and 12/12 to induce flower. Keep peak PPFD between 600 and 900 umol/m2/s during flower.

Q: How to handle nutrients if leaves show tip burn?

Check EC and pH first. Lower EC by 0.2 to 0.4 and correct pH to 5.8 to 6.3 in hydro or 6.0 to 6.8 in soil.

Q: What harvest indicators work best?

Use trichome color and pistil percentage. Target 20 to 30 percent amber for a relaxing, sedative effect.

Q: Can I grow Blue Donut in a small tent?

Yes. Keep plants short with topping and LST. A 60x60 cm tent with 2 to 4 plants per tent works.

Q: How long does curing take?

Cure for 2 to 4 weeks in airtight jars with daily burping for the first 7 days. Longer cures improve smoothness and flavor.
