Here you can see the syphoning in action. I have not tried it myself but I don’t see any reason if you bought multiple kits and stack them as high as you want and have a sprouting factory on your kitchen counter. Overall I was very impressed with the sprouter it was easy to use...
Install a rain barrel (they have complete kits there) New and improved grow box Shelves and lighting for seedlings next season Summer vegetable plants (peppers, tomatoes, cucumbers, etc) for those I was a little too ambitious with earlier this season. None of these sound good to you?
