You mean runoff like until it is flowing out through the base of the fabric pot?
If some mediums are allowed to dry out they can actually allow water to run off as opposed to soaking it up. During the summer here sometimes I'll get a little behind and when I do water it runs straight down the sides and right out the holes in the bottom. I can pour five gallons of water and watch 4.9 gallons run straight on through not providing any water to the plant at all. In cases like that you have to water a little, wait and repeat until you don't see any water running out of the holes. Then you know the plant is getting it. You don't have to dig to see if the medium is moist, just pick it up. Heavy means wet, light means dry.

Glad you got it figured out.
