It works fine for my neglected pepper plants, they got healthy new roots. It is a little difficult to build. You have to get all the little hoses … Read more Building an ebb and flood hydroponics system
I have redesigned my little box a bit. In the beginning, I drilled 5 holes for five pots. But because the hose was in the way, I could only fit 4 pots. So today I cut the hose short. Now I can fit the fifths pot and only have the small hoses coming through the … Read more Hydroponics – Building a wooden grow box
On my windowsill, there are still a few, neglected peppers. I had tried to grow them in the winter. Since I was looking at Hydroponics, Aeroponic, and DWC (Deep Water Culture) for a long time, I got some missing parts in the DIY store today and made a prototype. Building a hydroponics prototype Basically, I … Read more Hydroponics – First try with some bell peppers
