Home aquaponics kit - possible use for orchids?

[escualida]

So I funded this kickstarter project a while back Home Aquaponics Kit: Self-Cleaning Fish Tank That Grows Food by Nikhil & Alejandro — Kickstarter and apparently they're ready to start sending them out to us. My original intention with this was for growing herbs like what they have in the demo, but I'm wondering if it would work for orchids? It seems like it's just a shared S/H setup. The only downside I see is that since they're sharing the water they would be sharing diseases but other than that what do you guys think?
