Green house CNC irrigation system

I am inclined towards @123Splat's view - unless the hoses are just very thin plastic tubes - maybe 6mm outside diameter or less.

Even then I have my doubts about moving the hoses around as the distances are likely to be quite large and will require a very substantial mechanical system - even if the weights to be carried are low.

And you would have to ensure that the hoses do not damage the plants.

A drawing of what you have in mind with approximate dimensions would be a big help.
