I purchased a countertop sprouter but lost the directions which were on a label wrapped around the jar. How much water to use? How much seed? I know

I have a small stackable sprouter. I soak the seeds overnight, then drain them. I'll add them in one even later on each tray and set it in a warm place, not dark but usually on a kitchen shelf. I use a spray bottle to spray them with water everyday. Generally I'll start one tray each day. This way all the seeds don't come in on the same day. Also, check the mfg site. They might have directions there too.

Since I don't know how large your sprouter jar is, I can't tell you exactly the measure of seeds it can hold. My quart size sprouter can do about 2-3 tablespoons of seeds. You soak the seeds in water overnight, and I prefer to use a combination of hydrogen peroxide and water- using 1 ounce of peroxide per 1 pint of water. It helps seed germination, and sanitizes them at the same time. After the soak, drain all the water off and rinse the seeds well. I then rinse the seeds twice a day, drain them well, and let it go until they are the size I want. You don't have to measure the water you are rinsing with. Just fill the jar about 2/3, swish it all about, drain most of it and repeat a second time. The second time, you drain it until you are only getting a few drops out, and put it back in your chosen sprouting location. You also don't necessarily have to keep them in the dark either. Lettuce, radish and most small seeds don't care. Beans are the only things you usually sprout that want it dark. Wheat sprouts don't seem to care much either- and if you want wheat grass, they will need sunlight to turn green.
