Just the day before leaving on a Thanksgiving trip, I finished assembling a tiered winter garden in my hothouse, and planted some seeds: greens, radishes, peas, anything I thought might work in only 5" of soil. The hanging troughs are 5' lengths of vinyl guttering. Taller plants like broccoli are in the ground under the hanging troughs. Also plants like beets that have large bulbs.
I had no idea if this would work, if the watering was right, enough drainage holes had been drilled, etc. The watering system is 1/4" spaghetti tubing with an emitter every 12". It was set to water once a day for 15 min.
So you can imagine how pleased I was to return two weeks later and find the garden looking great!
