<span class="link_user">@allfish</span>, The compost tea I use is pretty easy it's made up in two parts so that it doesn't basically eat itself alive before you use it but it's called boogie brew. If you look it up on YouTube, he has a list of ingredients to make your own or you can buy his. It's kind of a lot of stuff you can make a way simpler tiara just like worm castings maybe some kelp and molasses is like a really simple easy one.. There's an old video to this open source compost brewer that uses some small PVC and a Rubbermaid trashcan to aerate the water. You also need a air pump. If there's more you're interested, and I'd be happy to help
