Q.Moisture meter for use in lava rock planting medium
We purchased a Kentia palm that was potted in Hawaii in lava rock. I tried inserting the moisture meeting I use for my indoor plants potted in regular potting soil but the meter wouldn’t go down and as I forced it the meter bent out of shape. Are there meters that are strong enough to be used in lava rock planting material?

The pro model moisture meters have a thicker probe. Although I can't guarantee that your lava rock planting medium will accomodate a moisture meter at all if it's that tight or rocky or root bound. Be sure that it has good drainage. If any doubt, re-pot, because it is vitally important.
