I've run these on full beds using sfg, one dripper per square. The larger model (c60) actually waters three separate 13mm dripper lines set up in rings around the base of 20year old apple treas
(Err, not sure that made sense: three trees, each has a large 13mm poly dripper ring around the base. The c60 feeds all three simultaneously. At my previous house it actually watered three seperate beds - two 2x3m , one 1x1m)
I have a C24 watering a 1x3m bed with a banana tree. You can get a lot of water out of those buggers and you can tweak higher flow dribblers and 4mm weepers
