Watering plants in case of absence

Question

I have around 10 planters at my flat, which I keep in open and water them twice a day. I generally go out for couple of days and am just worried if that duration increases plants may die due to water shortage.

I just wonder, what simple solution can be there. I thought if I can put a bucket, and then some rope/cloth kind of thing which may soak water via capillary action and quench the thirst. Not sure if it will work.

Any other simple tips which may not require use of electricity?

Thanks
