Garden watering system.

I will be away for a few days and the seedlings can't be let to get dry at this time of the year. Not much time and I as always work on a budget:  Reviewed the timer tap controllers and sprinklers. Picked a controller from Jaycar and tried a rotating lawn sprinkler.

I thought if the timer software is not good but the hardware is Okay I might gut it and replace it's brains with a Arduino type controller then get all sorts of remote control. The hardware seems fine so far though and the software too. Lets leave it at that for now.

The lawn sprinkler just did not work and stuck after half an oscillation. I returned it an got a simple cone spray that is meant to stick in the lawn. I mounted it upside-down over the main garden and used the timer to set it running for 15 minutes at 6 am and 6 pm. It seems just fine for late spring and did a great job while I was away for 5 days.

I might tap into the hose that runs along side of the house with some screw in spray nozzles to water some potted plants to the along there. I put these pots in the empty spots of the garden under the timed sprinkler while I was away and that worked out well but I need that space to let things grow so the pots need to go back.
