- My gardening experience, links to resources and good gardening information.
Saturday, September 7, 2013
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. I'm leaning towards Bio-Ponics because
I'm 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.
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.
