Melissa,
I don't know if you've already got them into the ground, but I've been keeping some semps strictly inside as an experiment. The one thing I've found is it is definitely better to under water them than to possibly give them too much water. The main issue I've run into is rot due to too much moisture (even though I very rarely ever water or mist them).
So now I error on the side of too little moisture and they appear much happier.
And I also agree with Bev, be sure to only mist/water the soil, not the semps themselves.
