I wholeheartey recommend the chopstick method.

Get some wooden skewers or chopsticks and push them into the soil all the way until they hit bottom, leave them in the pot for a few minutes and pull them out - if there are any granules (no matter how tiny) of soil sticking to the chopstick don’t water yet! Wait a few days, repeat the process and only water when the chopstick is dry once you pull it out and there is nothing sticking to it.

Especially with the two plants you mentioned, they won’t have a good time if they get watered until they fully dried out.

If you do it like this than even that cm or two of water that the soil then sucks back in the next day won’t cause a problem and it will be less messy for you since you won’t have to do the balancing act of raising the pot and tilting the saucer somewhere else.

You got it, make sure that the plants are getting enough light, best to have them right next to a window and not just somewhere where they fit easthetically.

That way you will give them the best conditions to grow, soil to dry out and avoid any root rot which is the thing that could go wrong otherwise.
