Earthan Beds

Over the past 21 months I have experimented with variations and combinations of Aquaponics, (vertical towers, wicking pots, deep water culture, and media beds), plus several other gardening methods such as Bio-Ponics, Wicking Beds, Hugelkultur, Two forms of Hydroponics (Dutch Bucket Hydroponics, and Kratky Method), and Dirt.







What I discovered worked best for me was all of the ponic methods -Aquaponics, Hydroponics, and Bio-Ponics The Kratky Method (a form of Hydroponics) also worked well.


Wicking beds or Wicked Beds as the Aussies like to say,  provide uniform moist soil,  even when I forget to water, and they conserve water due to the bottom up watering method.

The Ponics which are not normally soil based, provide nutrient rich water on a regular basis.

I am now ready to combine the techniques that I found worked best for me.  I was working toward this conclusion when I saw this link to the Earthen Group.  The details of this solution were instantly clear to me.  Paul Van der Werf  appears to have worked out all the kinks, and has detailed the construction of his system in the link above.

Since I built my Wicking Beds as conventional raised beds, and used sand in the reservoir I will have to replace that sand with 1-1/2" drainage rock in order to facilitate the faster movement of water from the Bio-Ponic or Aquaponic system.  Im leaning towards Bio-Ponics because Im not into eating fish, and it comes with less overhead.  Either way the nutrients will flow below the soil in the Wicking Beds.

This should create a very large area for nitrification, and be very good for the fish if I choose that path.  CLICK HERE FOR UPDATE

I considered utilizing one bed for the soul purpose of vermicomposting  Eisenia Hortensis (European nightcrawler) or more likely Eisenia Foetida (the red wiggler, Californian red worm).  But the leachate from a worm bin would not be beneficial to an aquaponic or even a bio-ponic system.

Converse  wrote a very good description of the risks involved. [LINK]

To be clear-  keeping red wigglers in all of your grow beds is a good idea, but the leachate created in composting worm bins is better suited for a Bokashi Compost than used directly in the garden, or introduced to aquaculture, so even though it may sound like it would increase the micro-nutrients in the soil, it is not recommended.

Construction of 8 Watt Earthan Beds


This video shows the construction of my Earthan Beds using an extremely quiet 8 Watt General Hydroponic Air Pump, and four individual air lift pumps.  Watering from below the dirt provides the perfect moisture with very little evaporation, and makes gardening easy.  The beds will remain moist for a long time even if you are away and the sump tank runs out of water.

The economy and dependability of the air lift pumps combined with recirculating water are so appropriate during this era of water, mineral, and energy shortages.

Earthan Beds provide the advantages of bioponics or aquaponics with real dirt where the soil web is allowed to flourish. 

Nutrients can be supplied by eco-friendly methods such as urine or weed teas.  5% of the natural gas we suck from the earth goes into making fertilizers.  Phosphorous is becoming harder to come by and some estimate our reserves will be exhausted within 50 years.  Urine contains amply amounts of nitrogen, phosphorous and many other trace minerals.  Less than a century ago none of the nitrogen was supplied by petroleum. Instead microbes made nitrogen available to our plants. The aerated water circulating through rocks you see in these beds provide the perfect environment for nitrification.

Return to natural resources.  Grow your soil and your plants will take care of themselves,

Ground Level Earthan Bed Concept


 Version 2 improves the placement of the airlift pump


The cost of building raised Earthan beds has caused me to consider using EPDM or other pond liner materials in an trench dug into the ground.   Due to my preference to use air lift pumps I had to find a way to economically create a deep well for the air lift.  This video shows my solution.

I have found a 20 lpm pump that is extremely quite.  It has a pressure of 84 inches of water, and runs on just 8W.  But the noise of gurgling water from the air lift may not be good for your location in which case I would suggest a small impeller pump.
