Bio-Set Siphon Cap

Bio-Set is our least favorite Sprouting Device, but we sold them for years - for those of you who don't care what we think. Good for you! This is the amazing, vanishing siphon cap that covers the little tube on each Bio-Set growing tray. Bio-Set won't work without these, and since they do seem to disappear, we thought it a good thing if you could replace them.
