I use coir with perlite or straight. I amend it with EWC and compost and feed with mineral salts. I reuse it at least 4 times before discarding it by simply cutting the old stem and root ball out and just dropping a new plant into the hole. I can garden almost exactly like you would with soil in containers. I hand water drain to waste and drench with compost tea.

When your done with it, you can till it into the ground. 100% organic.

Sounds better than rockwool, I am thinking if this works we can cut our media costs down to 1-1.5 cents per 2" pot.

Now coir is going to hold a ton of water. You may want to look at a high fiber blend, or of course use perlite with it. There's a company here in my hometown that is making a product called growstones. It is some type of expanded glass. It too is real nice to mix coco with.

I have perlite for it, what kind of ratio do you recomend?

I haven't used it quite the same way so I can't really say. I know you can get the more fiberous or even the chunk variety which may be better suited to your needs.

Now if you talking seed starting it is killer straight or blended w 20% perlite.

I will try that, I have course I intend to put in the bottom and fine for above that. Don't want it falling through the net cups.
