A look at the construction of my Earthan Beds. Previously these beds
were Wicking Beds with sand in the bottom, but now I want to be able to
let aquaponic water flow freely through the beds so I've replaced the
sand with rocks. The soil I place back into the Earthan Beds is a mix of
sand, compost, pumice, and garden soil, amended with Azomite. Pumice is
not required, but it provides plenty of surface area for bacteria while
making the soil light and airy.
When I first started to use my wicking beds I noticed the smell of
anaerobic bacteria. By allowing some water to flow out of the overflow
tube each day I was able to prevent this anaerobic condition. When I
removed the sand and soil from the wicking beds I found no sign of
By letting the water flow through the Earthan Beds I will create a good
environment for nitrification and prevent anaerobic conditions. The
water from the Bioponic System will also provide nitrates and other
elements for good plant growth.
