So, I've gotten a request or two to show step-by-step how I'm going to do the weekly lettuce project. Basically, I'll be growing hydroponic lettuce, in individual containers, without any electricity, I'll be starting one new crop each week, and hopefully getting a new head of lettuce to eat weekly, if all goes well. I'll post a link here so you can read the original thread, where I got this idea. http://www.preparedsociety.com/forum/f14/started-my-new-years-lettuce-today-16340/ Keep in mind, I'm terrible at gardening, and have never grown anything hydroponically before. That's kind of the reason why I wanted to try this. So easy, even a caveman can do it, right? Even though I'm on phase 3, I'm only going to post phase 1, and share observations as I go. So, on with the show! Phase 1. I'm using rockwool as a growing medium for the lettuce seeds. I'm also using Burpee seeds. Rockwool needs to be soaked for about an hour, and the general opinion is that a PH level of 5.5 is ideal for the water. I don't have a PH meter, so I skipped that. :sssh: Here is the soak. After soaking, I used a toothpick and made a hole about 3/8 of an inch into the rockwool, and placed 2 seeds in. I then pulled just a bit of the rockwool over the top of the hole. I then placed the rockwool into the first dish, using a Gladware small round container. Seeds need to be kept warm, so I bought a "windowsill seedling heat mat" off of Amazon.com for $17. I know, this uses electricity, but since it's winter, and outside it's about 15 degrees, I needed the extra heat, and didn't want to set up a thermal heat setup right away. This will come later. The piece of fleece under the heat mat greatly increases the efficiency of the heat mat. It isolates the heat up, instead of heating up the counter as well. I took another identical Gladware container and place it on top of the one holding the rockwool and seeds. I then drilled 3 holes near the rims, and dropped 3 nails in, to hold the top onto the bottom. The two containers together creates a miniature greenhouse. Lastly, because seeds do not need, or like light, I covered the entire thing with another piece of fleece, to keep it nice and dark. The heat mat will be shared with sprouted seedlings, and they need light, so I had to cover this little guy up. In time, I'll be making something to direct heat and light so that I don't need electricity at all, but this will take a bit of time. First I have to make sure I can actually grow something! I'll post the next entry as things progress.
