Generating green wall

Hey everyone,

I am creating a wall with “bubbles” to put plants in.
I defined the region on a picture of a house (rhino file below).

But I am facing a few problems.

  1. I want the connections you can now see between them to be water channels. So that when water is poured in at the gutter at the top it trickles down. (now I use proximity but it’s too much channels and it doesn’t organize well)
  2. I want to work with different sizes of “bubbles” and I think I will do that with “pick’n choose” but I don’t know how I will make sure that these then don’t overlap.
