Self-watering pots/ planters

I have a place in my house that is a high ledge, and my husband is fairly insistent on the idea of having trailing plants up there that hang down. I admit they'll look great. But we live in Mexico and have our house cleaned by a cleaner. Part of her duties is watering the house plants. I do not want to make her get a ladder out and climb up there to water plants. I'd be willing to take on the watering duties or assign them to one of my teens but no more than once a week because of the aforementioned need for a ladder.

I remember seeing ads for self-watering pots, are they any good? can I make something along those lines? I live in a semi-rural area so we don't have a big modern garden center to buy all kinds of pots/planters, I can of course order something online, but if I can make it myself, I'd prefer to do that.

The plants would likely be pothos or possibly a trailing succulent to minimize watering?

I've had a lot of success with diy wicking planters. I have a store bought self watering planter that works well but it's water reservoir is mosquito accessible. The diy planters are pretty easy to make.

I have in the past used lots of self-watering planters.

These planters have a tray at the bottom that allows the water to drain to the bottom so that it is used by the plants.

Depending on the plants chosen as to how often the plants would need to be watered.

I feel that trailing succulents would be a good fit for what you want to do.

String Of Pearls is the first one that comes to mind.

Another favorite plant is Burro’s Tails.
