Hello Again, I think I was typing while Baja was posting, sorry for any confusion.
Watering indoor plants is more complex than it seems at first. Here are some factors to consider:
Potting mix
Pot/drainage
Pot size
Temperature
Humidity
Air movement
Type of plant
Light exposure
Growth phase (growing or resting?)
Water hardness and pH
Oh yes, and BTW, water amount and frequency.
I'm sure there are others.
So there's no easy answer for the "how to water" question.
Also, it's ok for most cacti and succulents to be un-potted and dry for a week or more. Don't feel like you have to pop them right into new soil, they actually do better with a little time to rest and dry out.
Once they're re-potted, don't water for at least another week.
