Siphon mixer
From Freephile Wiki
If you need to apply a liquid (such as worm castings tea, compost tea, or even beneficial nematodes) to your lawn or garden, you can use a "Hozon" siphon mixer at the spigot, or at any junction in your hose to automatically dispense liquid from a container at a ratio of 16:1. Unfortunately, using a siphon mixer for organic materials may not be appropriate unless you are drawing water from a well. If you have municipal water, then the chlorine in the water may kill the organics while you're applying it.
