Stefan, i think most UK keepers use nest boxes because of the problem of heating large soil areas, what i should of done is sat an 8x4 sheet of 1" marine ply on blocks & stuck one of those mini oil heaters under it.

I always new that the viv would have to expand at some stage, so that's what i'll aim to do in the next stage, i like playing & building for some reason!

Over the years i've had plenty of advice offered by some proven breeders on nest boxes, but even with all that advice you still don't know if the bloody things will work when you need it to big time!!
