i think coco might retain to much water for a dwc
Seems like it might, but it doesn't. I'm running coco in DWC, and Zard has, too.

I messed up and ran the res level too high so the bottom of the netpot was actually submerged about .25". No problem. :thumbsup:

I use a special product that removes not only bits of stray root, but stray coco particles as well! Pretty pricey, though. I'll see if I got a pic...BRB.
