Answer

White Widow yield: 400-500 g/m² indoors and 500-600 g/plant outdoors. Flowering: 8-9 weeks. THC: 18-25%. Plant height: 60-100 cm indoors, 150-200 cm outdoors. The strain is a hybrid of Brazilian sativa and South Indian indica. It came from Greenhouse Seeds in the 1990s.

White Widow Strain History: A Deep Dive into Its Legacy

Indoor yield

Indoor yield depends on light, pot size, and veg time. A 600 W HPS or a 450 W LED in a 1.2 m by 1.2 m tent gives a base for 400-500 g/m². Use 11-15 L pots. Veg for 4-6 weeks. Flip to 12/12 when the canopy fills 70% of the tent. Keep temperature at 20-26 C. Keep humidity at 40-50% in flower. Feed EC 1.2-1.8. Run 2-4 plants per m².

Outdoor yield

Outdoor yield: 500-600 g/plant. Start seeds indoors 4-6 weeks before the last frost. Plant in the ground after the last frost. Use a site with 6-8 hours of direct sun. Space plants 1.5-2 m apart. Outdoor plants reach 150-200 cm. Harvest in late September to mid October in the northern hemisphere. In the southern hemisphere, harvest in late March to mid April.

Grow setup

White Widow grows in soil, coco, and hydro. Soil pH: 6.0-6.8. Coco pH: 5.8-6.2. Hydro pH: 5.5-6.0. Water when the top 3-5 cm of soil is dry. Add perlite at 20-30% for drainage. Use LST in veg. Use SCROG to keep the canopy level. Defoliate leaves that block bud sites at day 21 and day 42 of flower. Do not remove more than 20% of leaves at one time.

Flowering and harvest

Flowering takes 8-9 weeks. Check trichomes with a 60x loupe. Harvest when trichomes are cloudy with 10-20% amber. Flush for 7-10 days in soil. Dry at 18-21 C and 50-60% humidity for 7-10 days. Cure in jars for 2-4 weeks. Dry yield is about 20-25% of wet weight.

Mistakes

Do not veg longer than 6 weeks in a 1.2 m tent. Do not use pots under 11 L. Do not keep humidity over 60% in flower. Do not feed nitrogen after week 3 of flower. Do not harvest on the breeder week count alone. Check trichomes.
