Worm compost tea vs. worm bin drainage

If you're reading my blog, then you probably know that worm compost tea is great for your plants. I want to make a distinction though: worm compost tea vs. worm bin drainage.

In my mind, worm compost tea is distinctly different from the liquid that drains from some bin designs (what I call worm bin drainage).

Worm compost tea is made by separating the vermicompost from the worms and steeping the worm compost in water to make a tea. My website has complete instructions for brewing up your own worm tea: 1# of vermicompost in a 5 gallon bucket of water.

I don't mean to say that the drainage from a worm bin would be bad for plants. From what I have read it is great fertilizer; however, I'd be concerned about putting it on edible veggies because you do not know what is in it. I have also found a variety of different reports on how to use it ranging from straight (undiluted) to diluted to the color of straw. If I were to use this on salad and other greens I probably diluting it to straw color and bubbling air through it for 12-24 hours using an aquarium bubbler.

If anyone has experience using worm bin drainage, I'd love to hear how you prepare it for use.

Cheers,
Mark
