Glass Watering Sphere

Doesn't work very well. I've used this a half dozen times an the results are always the same. After filling the bulb with water & inserting into the soil, all the water has drained out within 15 minutes or so. I was hoping to use this when out of town but it's really not up to the task.

Convenient, last for maybe 2 days, wish it was bigger

It's really pretty but it is a little small and the tube gets clogged with dirt so I'm not really sure how good it is for keeping your plants wet. I'm using mine decoratively.
