Thwack, thwack, thwack! Bad Reuters! This is not the plant saying it's thirsty, it's some sensor designed by humans and set up by a retail member of Joe Public based on soil composition and plant characteristics.
I predict lots of misconfiguration with the result that genuinely thirsty plants stay thirsty and drowning ones get swamped...
"Because the plant said so"
See also: driving into lakes "because the satnav said so", installing trojans "because the computer said so", and consolidating all your government debt into one monstrously unwieldy albatross "because Gordon Brown said so".
Hmm - that seems to have annoyed me :-)
