Place the Jar in a spot about 70ºF (not much above 72ºF and not much below 68ºF) and ferment for the time specified. Desirable LAB flourish optimally at about 70ºF while culturing most vegetables. Temperatures too low will slow down the fermentation process, and temperatures too high will either kill them, causing the fermentation process to proceed too quickly, and/or cause undesirable softening of the vegetable. Each species of LAB has an optimal temperature range (yogurt LAB like 105-112ºF). Follow the temperature suggestions in the recipe for optimal results.
