Here are a couple of sketches of what I’m going to try to build.
I’ve picked a not-that-sunny window in my kitchen, and want to build a system for growing various herbs that my wife and I like to cook with – thyme, basil, oregano, marjoram, cilantro, parsley, etc. I think I’m going to try nasturtiums too. I want to avoid hanging things vertically, and am thinking of three angled tubes with holes cut in the top for plant cups. Inside the large tube will be two tubes – a 1/2″ feed tube with some kind of drip emitters attached at the top of each cup, cups will be in some kind of tiny funnel, at the bottom will be a second drain tube. Hopefully all that will fit in a 4×4 square or round tube. I’ll have some kind of lights on either side of the windowframe to supplement the low natural light.
Feel free to contact me if you have questions about the design. I’m researching both how to apply drip irrigation parts to a vertical system like this, and whether there are eco-friendly alternatives to PVC as a building material.
