mist hydroton surface?

[VickiC]

I seem to remember reading a thread or post reply sometime back concerning misting the surface layer of hydroton in S/H. If I recall correctly, will you please refresh my memory as to the purpose of this?

I would appreciate your help,
Vicki

In drier atmospheres, and/or with inferior LECA, the wicking cannot keep up with the evaporation rate, so you get significant drying of the top surface, potentially with deposition of minerals from the fertilizer solution.

When that happens, sometimes plants' roots will "shy away" from penetrating it, so by keeping it moist, the top is more "root friendly".

Thank you, Ray. This is exactly what I needed to know. I was hoping Mr. S/H himself would come through for me, so thanks again.
