I assume you're using it to supply water to the plant, rather than drain water from the soil - yes? Are you aware of a fairly major drawback to using this method?

What is the draw back?

..... rapid accumulation of soluble salts in the medium. You'll still need to flush the soil thoroughly and frequently from the top to control it.
