I gave my talk on Hobby Hydroponics at the library in Harrisonburg this afternoon. It's always a lot of fun for me and the folks that came seemed to enjoy it. In the talk I cover hydroponics basics and talk about the various kinds of systems I've made over the years. HERE is a link to one of my early stories for The Growing Edge magazine which is no longer published having met the fate of many small specialty magazine with the growing dominance of the internet. I think I'll have to put together some sort of mosaic image showing all the different system designs I've played with over the years.
I really like the nutrient film technique (NFT) systems but they need continuous flow which means if you lose power you may have a problem since the flow stops so you might want to ensure that there is a little nutrient retention in the design to keep the plants from drying out if that happens.
I'm also growing increasingly fond of float systems but I don't have a good tomato support design for those. I really want to get back to doing hydroponics and giving talks like I did today are very self-motivational.
