Indoor plants

I have quite a few indoor plants (mainly cactus and herbs) that are in planters that do not have drainage holes on the bottom. I can't tell if I am overwatering. Should I find new planters with drainage holes? Any suggestions?

Cacti and herbs both need good drainage. Water collecting in the bottom is not good for these plants. I would re-pot.

If you have them in pots with a hole in the bottom, then you can place those inside your ornamental pots - when you water you can then tip away the excess a few minutes after watering.

I really think that you'd be wise to do just that, or else to buy those little gadgets that tell you what the moisture level in the compost is.
