Another important part of this automatic irrigated raised garden project is rainwater gathering. Instead of using expensive house-water, we can gather and use “free” rainwater from the sky. Untreated rainwater is more health for the plants.
I’m using two 55 gallon drums that I was able to find on craigslist for about $20 a drum. I got an extra two drums for my brother.
All four drums fit snugly in my minivan for transport back home.
After getting them home, I need a support structure to put them on. A friend of mine offered me a pre-built structure that his mother was using. I accepted and with a few modifications, this is the result:
This is situated right around the corner from the first raised garden. It will not take much tubing to get the water there. Also, the top of the drums is 7 feet. This will give me about 3 PSI of pressure (assuming 2.3 ft/PSI). That should be enough pressure.
Update: this post has been over a month in the making. During that time I’ve had no rain to fill the drums. I have water now and it works! Part IV we will look into hooking up the Edison and making a schedule.
