indoor garden- changi airport ,singapore

last June 2013, on our way for a vacation to Philippines, we had a stopover at Changi Airport, Singapore.
Had the chance to see the indoor gardens inside the airport.
I hope NAIA will do the same too,considering that we almost have the same planting varieties.
I know it will not cost that much when it comes to cost and maintenance, but the problem is the rampant corruption inside NAIA.
Well, I just have to appreciate the beauty of the garden for a while for i know once I step on my beloved country, it would be the opposite...but still i love my country and proud to be a Filipino.
