I have a lot of succulents and things that like to be fairly dry in pots without holes - just because I reuse bowls and so on. They seem happy enough with gravel at the bottom, you just have to be careful not to overwater. Other plants tell you when they need repotting because the roots get to the holes so it's useful to be able to lift them and check. And as others have said - anything that likes to be watered by soaking and draining needs a pot with holes.
I have a quick question. I’ve read somewhere that plants can be repotted into a pot without drain hole at the bottom as long as you provide a few cm of drainage using stones or similar. On the other hand my gf tells me that a drain hole is a must for plants and that they will grow better in a plastic pot placed inside a bigger ceramic/clay one. What’s your experience? I’ve been taking care of our house plants for some months now and have been repotting them into pots without drain hole and they seems fine and growing but want what’s the best for them.
