..oh most likely.

However in ur example of perlite, it holds water (otherwise ur plants would die unless water is constantly being pumped over the roots)...*and* is exposed to heat & light. Ergo, u will get evaporation in same manner as soil, probably fairly close % wise...anyone got plenty of time on their hands to do a side by side comparison in 2 cabs....JF? :p
After a while, people are just going to ignore it, like I did, like I do most TV commercials.

Juice?

If it's there to to hold roots and holds very little nutriant solution, it's a substrate.

I understood the werds,jesuschrist I aint totally tarded.....................yet.
Just seems to me the medium/substrate has to maintain a certain level of saturation or else the plants will die.
I don't water till runoff in soil,so seemingly the levels of moisture will be approximately the same.
Given the leaf cover and the hassle of even seeing the damn dirt to water I merely question whether the humidity levels are any diff at all.

A substrate doesn't need to have any saturation, it can be 100% inert

I would think so, but I think he was talking about hydro with rezes type systems.
