I am new to phals and am trying to figure out how to know when to water them. I have made up my own medium (Miracle Gro Course+charcoal+oregan moss+perlite+verticilium), which seems to be working well. I live in high desert (central Utah), so it is a dry climate, which is why I wanted more than just bark.

I bought a moisture meter and have been using it as an adjuct to visiually checking the plastic orchid pots, which are then place in a cachepot. I find that using a meter properly makes a big difference in accuracy.

Just wondering if any others have found moisture meters helpful.
