cut a fizzy drinks bottle in half,keep both halves.put the screw cap end,minus the cap in your grow bags,carefully at the same time as planting up,or next to runner beans in the same fashion,just above the soil level.
Thus allowing water/rain water to go straight to the root system.It also acts as a slug and snail trap!!!!!.
Save the other half to collect rain water in.
Nothing goes to waste!!!!
