Watering under cloches

Just a simple question.
She who must be obeyed bought me some lovely large plastic cloches for Christmas.
They stretch to about 5 yards long and are fixed to the ground with wire hoops (I'm sure you know the sort).
My problem is - how do I water the plants when the cloches sre in situe?
It would be a job to remove them every evening, water and then replace, single handed.
If I water over them so the water runs down the sides, will that get to the plant roots?

Once plants are established I don't water much at all. Under cloches they tend to keep damper anyway. When the weather gets better you'll want to take the cloches off altogether.
