It is difficult to make such timers, and you won't be unable to read the time. There would be serious problems if you use such timers to your plants. There are more type of timers to protect plants. If your timer won't start when you are on vacation, then your plants will die.

The 555 manages about 1 moment. You need a program agreement to create the 555 manages 24 time wait. Why don''t just buy the 24 time clock insxpensive ly ??.
Please seek advice from www.circuittoday.com. There a lot of example about 555.

There are cheap timers that can do better than 555, I would like to suggest you to use Fronmtier timer that is here under store, try it as you wont upset for buying it.
