Auto-irrigation Raised Garden – Part III: Rainwater

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.

  1. Awesome! Your auto-irrigation plan is definitely inspiring.
    I am also thinking of a similar idea for my family and happened to come across your page on that note. My situation is that my family owns a piece of land that is approximately five hours away from our hometown, so I want to decrease the amount of time they have to go over there and check on the crops.

    I’m an intern at Intel and will likely use the Intel Galileo as the startup board for the project.
    I will love to see how your project goes, keep us posted! (:
