Watch this video that few have seen. It features a Google chef and a local master gardener from Santa Clara County. Their presentation of the benefits of EarthBox gardening is persuasive.
If you have an open, inquiring mind, you will likely wonder as I do why the news about EarthBox gardening and sub-irrigation (aka self-watering) is virtually ignored by the mainstream media, USDA extension program agents and urban botanical institutions.
It is a testimony to our antiquated horticultural education that is stuck in an out-of-date dirt gardening paradigm inappropriate to urban living. It is quite amazing that we have so many academics with master’s degrees and doctorates that apparently do not understand the fundamentals of capillary action and plant physiology, no less urban living.
If you think I have some connection to EarthBox, you are mistaken. They just happen to have the most commercially visible product at this time. I have no connection whatsoever to EarthBox. My advocacy is simply about growing food and feeding people in the city using the most environmentally sound and productive methods available.
Anyone can easily prove the following for themselves, no institutional help required. Simply plant one or more SIP boxes or buckets this season and you will see with your own eyes.
Benefits of sub-irrigation planter (SIP) gardening including the EarthBox, Tomato Success Kit, Garden Patch Grow Box, EarthTainer and all other properly made DIY SIP planters. There is no patent on capillary action.
Increased production – SIP vegetable gardening will out-produce all other methods including in-ground and raised beds with drip irrigation.
Safe food production – Sub-irrigation box, bed and bucket planters will produce contaminant free food. Unlike dirt gardening in the city, there is no exposure to native soil contaminants.
Water conservation – All of the water (and nutrients) go directly to the plants. There is no wasteful drainage.
Portability – SIPs can be located anywhere there is adequate sunlight regardless of access to tillable land. Personal, neighborhood and community gardens can be located temporarily and easily moved when necessary.
Sustainability – SIPs and the soil mix in them is reusable season after season. Yes, there is an initial cost but they are not consumables. Currently, there are business plans based on a 7-year useful life. Time will tell whether this is an accurate useful life.


Prominent Leaders Support Sub-irrigated Planter (SIP) Gardening
While our USDA extension program, the National Gardening Association and others in the media drone on about “you’ve got to have a drain hole” nonsense, we’re fortunate to have two leaders like Dr. H. Marc Cathey and Vint Cerf.
They are advisory board co-chairs of The Growing Connection, a U.N. agency, which is a major supporter of sub-irrigated planters through its connection to the EarthBox.
Dr. Cathey is President Emeritus of the American Horticultural Society. I’ve known of him since my first days in the interior plantscaping industry back in the mid ‘70s. As a speaker at our trade shows, he was a big help to all of us groping our way along in a new industry.
Vint Cert, known as a “founding father” of the Internet is Vice President & Chief Internet Evangelist of Google. Of course, we all know about Google, a major success story in the history of U.S. business.
I would not know what I know about our out of date horticultural education without Google web and individual site searches. Both good and bad information have no hiding places from Google.
It is perfectly understandable why they would be supporters of the EarthBox as a company. It is the only high profile name brand in the field of sub-irrigated food planters.
Recognize however that although the EarthBox is a patented product, no one can patent the benefits of sub-irrigated planters. Sub-irrigation, along with its benefits, is in the public domain.
Whether you plant in a repurposed pop/soda bottle, an EarthBox, or any of the inappropriately named “self-watering” planters the core principal is the same. Whether you are growing tomatoes, or houseplants the core principal is the same.
Water moves up from a reservoir into the soil via some form of wick by the basic principal of physics called capillary action. It is just that simple.
As the EarthBox has proven, vegetable production is dramatically increased with water savings in the range of eighty percent. These benefits attracted The Growing Connection in its work with third world countries with scarcities of rich soil and water. It is also the ideal approach to urban agriculture where open land and space are at a premium.
If two distinguished professionals like Dr. Cathey and Vint Cerf can see the benefits, why is that so much of our horticultural bureaucracy cannot. Why are they still playing with clay?
