Lacto-fermenting ginger root: 2.50% salt, 7.0days at 68 °F
Aromatic rhizome used as component (<5% of ferment weight) rather than primary. Can also be standalone for ginger-bug (starter culture for sodas — natural yeast + Lactobacillus from the skin).

Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.
For ginger-bug: grated ginger + sugar + water 1:1:10, loose lid, feed 1 tbsp each ginger + sugar daily for 5-7 days until foamy and smells bread-like. Use as soda starter (~1/4 cup per quart of sweetened tea/juice). For kimchi/hot sauce component: grate, add at 2-5% of primary vegetable weight.
2.50% by weight is the default for ginger root (workable range 2.00%–3.50%). For 1000g ginger root, that's 25.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: Sandor Katz — Wild Fermentation (ginger bug).
How long to ferment ginger root?
7.0 days at 68°F (20°C). Cooler kitchens (60-65°F) slow fermentation; warmer kitchens (75-80°F) roughly halve the time per 10°F increase. Start tasting from day 5; target pH 3.80 or below indicates complete primary fermentation.
What's the best technique for fermenting ginger root?
