The white plastic piping and valves is pvc. Very susceptible to uv damage from the sun. You should use the grey stuff, cpvc. It's expensive, but worth it.

I remember reading Elliot Coleman saying that most vegetables require something close to 90% humidity in a root cellar. He spoke of tossing buckets of water on the floor, if necessary, to achieve such.
I always wondered about that causing mold issues.
I plan on constructing a root cellar on my property. Any words of advice or essential reading suggestions from anyone?
