Hi guys, I've just set up an exo terra 60x60x45 cm for an amazon tree boa. I've modified the top with Perspex to replace the mesh lid. Using a radiant heat panel for heat. The problem is on the cool side the humidity is 20% more then the hot side, just wondering if this is normal? And where should I place the hydrometer probe? Thanks
Hello. It's perfectly normal for the cool end humidity to be a bit less than the warm end of a cage. Put the probe at the cool end and you'll be fine.
In that size of habitat I'm thinking you're getting false readings. In a distance of 2ft I wouldn't think it would change 20%. But then even if it is, it's good to have a variance in humidity.
Whoops, wrote that backwards, lol. Should have said more humid on the cool end. Sorry, blonde moment there.
Heat sources dry out the air, so that doesn't seem like too much of a variance. Shouldn't be an issue.
Looks like you have a pretty thick layer of cypress mulch in the bottom? Just keep that moist and the humidity should be fine as long as the top is mostly covered. I'd start planning for a larger enclosure though, that one won't be suitable for the long run.
And if you just want to play around a bit, try measuring it an inch off the floor at either end. Just guessing you were measuring near the top, which would probably kind of mess up the reading when close to the RHP.
