I have been waiting the moment to build my self watering metal trough planter. I finally gathered all the materials and put together one of them. There is a great PDF instruction put together by Mary Janes Farm.
I got the trough from Scottsdale Livestock Feed Supply for $85 each. It measures 2' x 2' x 3'. Just the right size for a small backyard garden. I am building two of them because I wanted to plant two asparagus seedlings in each, and hope to harvest the asparagus in them for years to come. And I will be planting some other companion veggies for year round harvesting.
They will be on casters so I can move them around through the year depending on the season.
Here's my rough plans for each of the planter. (t) means transplants and (s) means sowing seeds. I should be able to finish the second one in a day or so and start planting!
More updates to come when I am done planting.
