Here are a few shots of the planters themselves, to show how they are constructed. The green planters were made following my friend’s instructions, by cutting out a section of the plastic tub’s lid the size and shape of the tub’s interior about five inches off the bottom (the height of the pond baskets that drop into the water reservoir). While this results in a large tub, it is very time-consuming to do this.

Me second approach was simply to use two buckets, one which nests neatly and strongly inside the other. These two, the white one illustrated in the pictures and the black one in my previous post, took me about an hour to make both. I like this approach because of the ready availability of surplus materials to make the SIPs and the ease of making them.
