February 2013.

My new heavy framed ecobed replaces a conventional organic vegetable bed which had been growing potatoes.
  

The new bed is 2.7m long x 1.65m wide x 600mm deep.  A 600mm wide access path will be laid using the remaining space from the old conventional bed.  The wicking bed will be planted much more densely, and I expect to get a similar volume of crops from the smaller space.  For construction details see Making a Heavy Framed Ecobed.

The pest exclusion frame supports a large vege-net which is clamped at the corners using oversize pegs.  It is designed for low growing crops such as Beetroot, Carrots, and Onions.

Copper tape is stuck to the outside perimeter of the bed to keep slugs and snails away from the growing area.
