| I learned a valuable less about coir recently while starting some tomato seeds. Even at a depth of a couple of inches, the stuff stays incredibly wet, while dry or just damp at the surface.
I've had remarkably good luck with coir used in conjunction with a wicking mat (Burpee's), and gotten fantastic germination and roots. But to just water the stuff, it stays way too wet to the point of being soggy. I repotted the poor, yellowed seedlings in a peat mix, and within 24 hours, they had started to recover.
I think that a good use may be to just put coir only as the top 1/2" of the container. That's the next test, anyway.
