Well when I had my Pheidole pallidula they did like quite a damp nest but to be honest they aren't too fussy about humidity, but for such a small colony a test tube set up is the best thing, mine only moved into a sand nest when they had around 200 workers.
I think if you put them in a covered test tube set up they should settle down, letting them have anything bigger is a bit risky, you know they will be safe in a test tube set up until they have enough workers to maintain a bigger nest.
