I used to have a somewhat similar system in my old polytunnel, except the leaky hose (it was an old garden hose with holes made in it) was left in the beds, I just connected the running hose to each bed in turn and left it whilst I did other things. Over the years the hose gradually got buried, so it was mostly
under the mulch which accumulated. It worked well for me.
In my new tunnel I'm setting up a sort of self watering sub irrigation system with stick bundles wrapped with sheep fleece. It's experimental, so I don't know yet how it will turn out, but hopefully will water the tunnel inside when it rains outside (most of the time here!). I was hoping to eliminate plastic hose pipes.
