Message: <blockquote data-quote="m0lsx" data-source="post: 191075" data-attributes="member: 29323">I have been thinking about one of these for some time. As a few of our heavy webbing arboreals are in top opening enclosures & it is thus difficult to know, at times, just how wet or dry the substrate is. And at £6.50 including postage, I thought it was worth a try. I have tried this out on several enclosures over the past few days. Using it  where I can both feel the substrate with my fingers & look at the results with the probes & it will, I hope, give me a reasonable idea of what the substrate is like, in a heavily webbed up enclosure is like, If I cannot see it very well.We have rehoused 3 arboreals this week & all were heavy webbers. All 3 had substrate which was fine, but in the past, I have had an enclosure where the substrate was not just moist or damp.  But water logged. This meter will hopefully help to avoid that happening again. The issue that concerned me was, would this work in a few cm of substrate, as these probes are designed to be pushed several inches into a pot or down into the garden, down to root level. However my tests this week show it works just fine in 2-3 cm (1 inch) of substrate. It is never going to give me any useable measure of just how moist, or dry,  the substrate is,. But it will give me a much better idea of if the substrate is moist, wet or dry. [ATTACH=full]54464[/ATTACH]</blockquote>
