Ok fine.. rock wool is a wick, a really good wick. Too good for me... lol soaks up water like a sponge. But I still don't think perlite is a poor wick. If you put water in the bottom, the top will become wet by capillary action.
Oh and yes the rocks i used at first didnt wick at all. I think the top was only getting a little wet by evaporation, lol. But things still worked pretty good, although they probably werent getting any food until the roots hit the res.
