[net.garden] houseplant watering indicators

goutal@decvax.UUCP (Kenneth G. "Kenn" Goutal) (08/02/83)

Anybody have any experience with those little indicators you can buy
to tell you whether it's time to water your plant or time to lay off?
Do they work well?  Are there better methods?
Are there methods as good, only cheaper?
