I've heard of a few things that I thought were very interesting. like self watering containers? wha??? I almost break into the thought like a skeptic on an info-mercial, "so whats the catch mr self watering container dude" ... so I'm curious how people have used those and enjoyed them. also I've seen a strange dual bucket construction where the first bucket is usable by itself, and the second bottom bucket has a hole drilled in the side three inches up(approximately the gap created by the spacing built into the bucket for stacking) and aparently if you put a pipe down there and I don't fully understand the concept and I havnt found any good resources on this kind of construction
so has anyone used or built either the self watering container, or this bucket thing? and do you know where I can find directions on building one??
another interesting point is what kinds of plants do these best serve? if the water si welling into the plant from the bottom. they probably don't do well for plants that like to dry out like oregano. just a guess. any thoughts???
