I may have mentioned that we love gardening with these kids. Also I may possibly have mentioned that we kill a lot of plants. Well, look at us trying to beat that trend with science.
My little man and I put in some herb plants over the weekend, and this is our automatic irrigation system. A very classy look, right? In theory, as there is air in the soil that can move up into the bottle, water is slowly released, maintaining a steady moisture level and preventing a holocaust from over or under watering. And it’s a two minute recycling bin project. Since you can see the water level you have an obvious cue as to when you need to water. Should be interesting to keep track of how long between refills as related to the weather, yes? Back yard science AND keeping it classy.
I should explain a little about the milk jug. There are seven or eight holes poked in the bottom (I used a metal skewer) and the tightness of the lid controls the rate at which the water comes out somewhat. Last night before bed, I filled the jug with my little dude and tightened the lid all the way down. This morning when we went outside, the jug was flattened like someone had stepped on it- and I got to explain to him that we had created a vacuum using only water and gravity. He was completely thrilled! (I turned the water on high when I refilled it, and the jug popped back into shape.)
This sounds like a good idea for someone who would be far away for a few days. They can setup this can of irrigation system and feel confident that their plants won’t dry up before they come back. Thanks for the brilliant tip!

Also, after some time using the milk jug, I got tired of having the water run out onto my feet while I refilled it from the garden spigot. For my second milk jug waterer, I poked two air holes above the handle and six or seven watering holes on the other side of the jug. I fill it, cap it, and then lay it on its side. Works like a charm and doesn’t run out over my feet!
