Grow Cones Up the Wall

My Grow Cones are working really well, with big happy plants in little bags. However, they are invading every horizontal space I have, and I'd like to put them into a smaller space. I tried using shelving, but the problem is that when the plants get taller, they hit the "roof" and that is a problem. Also it is hard to get to the plants in back of the shelf.

There is a really nice idea here:

This is a hydroponic system, but my idea is to do the same thing, except using Grow Cones in the holes instead of  bare roots sitting in water. Each "rack" will be 3.3 feet long (1/3 of a 10 foot pipe), and the overflow from the top pipe goes to the next and so on. So there is only one water hole per rack. The pipes will hold 2" of water or so.

I'd like to have the pipes be portable, so you could detach one from the rack and put it on a table or use it in the house.

The idea is to be vertical. You can grow a lot of plants on a wall! I'm thinking one 3.3 foot rack of lettuce is about all the lettuce we could use, and if I could have a rack of strawberries too that would be great.

Now there is another gorgeous idea here:

Note what they are doing here, wrapping the roots in a bag. Basically this creates a growing medium very similar to Grow Cones, and enables the plants to be portable. Aerated roots are happy roots!  And note how very little root space a strawberry plant actually uses. Their system is way prettier, but probably overkill for growing a few plants outside.

I'm really liking the pipe idea. How about for taller plants? My experience this year is that even big plants don't need much root space, but they do need a way to hold themselves up. What about a long pipe, with raspberries or tomatoes in a row? Instead of being on a rack, there would be just one pipe, with a trellis attached for the canes or vines. Probably bigger cones, bigger pipe.
