Worm castings

I have used worm castings before but I was jus curious what is the right way or most effective way to use worm castings? Sorry I'm new to growing.

You can actually use 100% worm castings instead of soil. Worm castings are just cleaned soil that worms have eaten and digested. There is no perfect formula that anyone can use. As teh previous poster said yu can use anywhere from 10% to 100%, I usually use around 20%

Alright thanks guys. I heard you can also make a tea out of it. How does that work and how much do you use per gallon? And can you use it aas often as nutrients.
