In my experience as a sommelier and brewer, the fermentation process with Safale US-05 yeast typically takes around 2 days to get going. This means that you should start to see signs of fermentation, such as the formation of a krausen (foam on top of the beer) and airlock activity, within this time frame. However, it's important to note that every batch of beer is unique, and there can be variations in fermentation time due to factors such as temperature, yeast health, and the specific recipe being used.
Once fermentation is underway, it usually finishes all activity within 3-5 days. This means that the airlock will stop bubbling, and the krausen will begin to dissipate. It's important to monitor the specific gravity (SG) of the beer using a hydrometer or refractometer to determine when fermentation is complete. Typically, the final gravity (FG) of a beer fermented with Safale US-05 yeast falls around 1.010-1.012, but this can vary depending on the recipe and desired characteristics of the beer.
It's worth mentioning that there can be some variation in fermentation time due to different factors. For example, higher fermentation temperatures can speed up the process, while lower temperatures can slow it down. Additionally, pitching a healthy and sufficient amount of yeast, proper oxygenation of the wort, and adequate nutrient levels can all contribute to a healthy and efficient fermentation.
In terms of personal experience, I have brewed several batches using Safale US-05 yeast, and I have found that the fermentation timeline I described above holds true in most cases. However, there have been instances where fermentation took slightly longer or finished a bit quicker, depending on the specific conditions of each batch. It's always important to carefully monitor the progress of fermentation and make adjustments as needed to ensure the best possible outcome for your beer.

Monitoring the SG and observing signs of fermentation will help determine when the process is complete.
