| I would not worry about it either. Think of it as an experiment if nothing else. Particularly since your water is constantly moving, I'd agree with Cloud --if roots grow on the wet area, the plant will probably do just find. (I've seen a vanda in a greenhouse growing over a pond. Its roots had actually grown down 3 feet to the ponds surface and kept right on going. It had at least 3 feet -- about 1 meter --of roots growing quite happily along the BOTTOM of the pond. It is amazing sometimes what they can adapt to.) |
