Irrigation

I have been considering setting up a timer to water tomato plants for a while and am struggling with a problem.

If I use 4 LPH drippers, which seem standard then I will get 0.4L in 7.5 minutes but timers seem to expect timing programs that last 30 minutes and more - am I missing something

    Can I ask why you are doing this?

    I'm off on holidays soon but also my father was a keen greenhouse gardener and one of his pearls of wisdom was that you should be very exact in giving the same amount of water every day.

    Not for tomatoes-they do better being kept on the dry side.

    Have you a kindly neighbour?

    Tried that with little success

    Are you saying the amount of water should be variable depending on the conditions so that the plants are kept slightly dry?

    Yes-constant water is not good -they do not need it

    I thought that was what caused splitting - a surge in growth from a one-off over water

    Not really-but you must do what you must do

    How long are you leaving them?

    Can you set the timer 24/48 hours apart and for a certain period?

    I haven't looked at it in a while but there was something like 'for 6 minutes twice a day' or '8 minutes once a day'.

    I was wondering if someone would suggest a 1LPH dripper which I could set for 30 minutes - but I have never seen such a dripper!

    30 minutes a day is too much I think-I would suggest some experiments before you go

    I am now completely lost on what you are trying to achieveimage
