The water poured off during the draining process is chocked full of nutritients, so on plant-watering day, rather than just dumping it all down the drain, some of that water is reserved for my house plants.
Preferring to buy my goods locally, locating quality sprouting seeds was a challenge for me. Our Community Food Co-Op was the only store in our county where I was able to find sprouting seeds available. I was disappointed with what they carried, however, as they had a very limited selection and they were priced considerably higher than if ordered online - even after adding in shipping charges. The seeds that I purchased from them may not have been particularly fresh either as they took a few days longer than most sprouting seeds to sprout, and they had a very poor germination rate.
I ended up finding a supplier of high-quality, organic sprouting seeds online at wheatgrasskits.com. They not only carry a long list of seeds to select from but I consider their prices very reasonable. Their seeds are certified organic, seem very fresh and have a very high germination rate. Wheat Grass Kits also carries several sprouters if you want to use something other than just a plain old jar in which to grow your sprouts. My orders are always received within three or four days - even when placed during a weekend.
Here's how I garden in a jar.
It is important to utilize food safe, sanitary conditions when growing your own sprouted seeds in order to prevent the growth of bacteria. Several years ago, there were reports of e coli in sprouts so stores pulled sprouts and sprouting seeds from their shelves. Guidelines for safely growing your own sprouts at home have been made available, and UC Davis has published such a guide. You will find their guideline here - http://postharvest.ucdavis.edu/datastorefiles/234-412.pdf.
