What is a hydroponic system? I’m glad you asked. I had to look it up myself. It is a system that doesn’t use soil to grow plants but a solution that is water based and rich in nutrients (too smart for my brain!). One disadvantage that most people have found is that a quality system can cost quite a lot. You tend to get what you pay for so going cheap will result in low quality plants. Lucky for us there are some DIY versions out there are both quality and cost efficient.
Check out this one from Greenerways2012 shows how to grow 168 plants in an easy to make and portable frame. It is mostly PVC pipe and lumber. I don’t love the look of white PVC pipe all that much. I think that it sticks out like a sore thumb, especially in a green yard, but I do love that it can be used to make cool stuff like this and that it is affordable. If I was going to make this I would paint the pipes green.
Here’s the video…; Enjoy!
