I don't think so, not to my knowledge, if I were to use pots, I would buy the plastic ones, they're so easy to cut into the desired shape required, I think the OP has terracotta pots at hand - and would like to use them, there's no reason to specifically use terracotta ones, plastic ones are just as good, they may look unnatural but you can glue sphagnum moss to the edges, cover the top with substrate and boom you've got a lovely looking hide. A lot of bother to go to when you can use cork rounds or slabs buried into the sub, I have seen them used for T. stirmi the way I've described.
Will definitely try that. Hopefully it will work like acrylic, snaps on the weakest point.
My enclosures were particularly small and i dont have access to cork bark without an hour drive. So i just picked up these small planters.
If you've got a drill - you could drill holes at the halfway point using a carbide tip, then once you've drilled the holes, I'm sure a little tap would split the planter then you've got two equally sized hides!
This is definitely the best bet. It's the easiest way to ensure a good, clean job.
A Dremel w/the right bit will work. @EulersK knows!
Yup, it's just that the bit is very expensive and cutting the pots takes quite a bit of time. I prefer to use the claw of a hammer - I get a good even break about 75% of the time.
