Aqua globes

[actng]

does anyone have this? does this work?

the concept seems simple enough. As the plants dry, the soil releases oxygen which goes up the aqua globe and pushes water out, moistening the plant.

what i don't understand... is wouldn't it just mositen the immediate area around the spout? what about the rest of the plant?

we have some. mixed feelings, my wife thinks they work great, I think the stem gets clogged with dirt preventing anything from happening.
neither of us is any good with plants/flowers.
