I have been leaving a sprinkler on on my tomatoes if I go away. But last year everything was drenched and I lost the lot to blight/ grey mould.
This was partly the wet weather but as the water pressure varies sometimes the whole greenhouse was sprayed other times a small area.
So I would like to get a narrow seep hose to lay on the surface, or just under the surface of the bed. Then set it on the timer.
Can anyone recommend a narrow hose/ system, bed is 12ft by 4 ft.
