Homegrown Evolution is up in San Francisco this weekend to do a talk about the world of self-irrigating planters (also known as SIPs or self-watering planters or a couple of other variations on that general verbiage). In our opinion SIPs are the food growing tool of the aspiring urban agriculturalist. Make or buy one of these things and vegetable container gardening is a breeze. No need to water your pots three times a day during the summer! For those who can’t make our talk, and as a resource for those who can, we thought we would put all the Internet resources in one place in this here blog post.
SIP hacker and horticultural Internet hero Josh Mandel’s original pdf instructions for how to make your own.
Mandel’s revised instructions with thoughts on how to eliminate the use of PVC plastics when building a SIP.
Where to buy a SIP: earthbox.com. Even if you build your own, you should follow the Earthbox company’s user guide for how to fill the box, what kind of soil to use and how to fertilize.
For a nice example of rooftop and window gardening with SIPs see the Green Roof Growers of Chicago.
Last night we went to a wonderful screening organized by the folks at How to Homestead. They have an interesting SIP variation made with milk crates profiled in a how-to video by Mariana Lopez. She also offers a recipe for a DIY potting mix in that same video.
Ohio State University Extension Service’s list of vegetable varieties for container gardening. These are varieties with smaller root systems that do well in small pots.
Lastly, all of Homegrown Evoution’s self watering container posts.
