Where they do become any risk. Does depend on your practice and climate.
I leave out all day and all night. So 24hrs, and have had no issues, in all the time I have been sprouting.
24hrs!!! Right.
Sprouts are living plants, and will continue to grow as long as they are not damaged or dried out.
Those who are scared by claims of bacteria need to consider. Bacteria is both good and bad, and around us every day.
For those who are really scared off by those who keep going on about this.
You can try this. It is simple and will give you a handle on things.
Sprout, but do not put them out for your birds. Put them in a tray the same as you would, if feeding them out, and check them every hour or so.
Ok it may not be immediate that you will notice any change but you should be capable of noting changes.
The three tests are smell, feel, taste.
They are the same as undamaged fruit, they DO LAST in most climates.
It is once you cut things up that they can deteriorate quickly.
