The reservoir should be able to hold several days tannie of water, at the very least it should be big enough that you only have to water once a day, saving a lot of time.

Fortunately it's not hard to work around this, just use commercially made pots with a reservoir or make your own. Fruits and vegetables in containers. Another method is to make your own pot.

The simplest way that I have done this is to just take a 5.

Trying to grow most fruits and vegetables in a standard pot with drainage holes in the bottom can be very time consuming. Growing fruits and vegetables in containers provides a unique challenge, it can be hard to make sure they have plenty of water. One way around the problem of having to water so often is to buy commercial pots with a reservoir, often the bigger the reservoir the better.

In the heat of summer they often need to be watered several times a day, otherwise you'll get a lower yield, you might not even get a crop if you just miss a couple days watering.
