Grow Mediums Worm castings in DWC...

Anybody ever throw these in a DWC reservoir?

Why would you want to introduce what is basically soil into a hydro application? Worm castings require myco to break down the nutrients and make them available to the plant. So unless you also added myco, they would basically be worthless, to say nothing of what they might do to your pump.

It’s not soil, it’s nutrient — which is why I’m curious about using it. I use Enhance MC in my DWC reservoir, which requires no pump.

Technically, it's compost, which is a soil additive. Worm casting are worm droppings, much like manure is animal droppings. Why anyone would use compost in a hydro system is beyond me. In fact, I don't agree with running anything but sterile in hydro. So much easier to manage and less costly due to fewer nutrients, no teas, etc.
