Home Gardeners

iAVs offers home gardeners the means to grow clean fresh fruit and vegetables…and freshwater fish…in their own backyards.

Indeed, the iAVs promise states the method has the capacity to produce fish and fresh vegetables sufficient to provide a family with 200 kg of fish and 1,400 kg of vegetables (fruit) per year in a footprint equal to an automobile parking space. *

*Assumes a sub-tropical or temperate climate or controlled environment that will permit year-round plant production.

6 Steps to iAVs Success

Important Message

Think of building an iAVs as being like baking a cake.

Recipes are guidelines that allow home cooks to produce a satisying result – without the need to acquire the knowledge and skills that would otherwise be required if you did not have the recipe.  A recipe is a “quick start up guide” – a means of being able to produce a result with a minimum of fuss.  To that end. we’ve provided you with the iAVs Recipe for Success.

If you’re new to iAVs (and everybody is), you are strongly advised to use this recipe as your starting point.  As you gain knowledge and skills, you will eventually be able to vary the process….but you’ll be doing so from a position of experience…..and there really is no substitute for that experience.

The Equipment and Ingredients that we’ve stipulated are essential to iAVs.  Without sand, it’s not iAVs…..and without furrows, it’s not iAVS…..just as a chocolate cake without the chocolate is not a chocolate cake.  Every aspect of the iAVs is there by design.

OK…so what if you live someplace, for example, where tilapia are a prohibited species…or where it would be cost-prohibitive to maintain water temperatures ten degrees higher than the ambient air temperature – for months on end?  We acknowledge that there are situations where it is simply not possible to comply with our recommended Operating Instructions. In the examples we cited, a substitute species will need to be indentified…or a controlled environment will be necessary.  These deviations from the recipe can be accommodated with our help.

In essence, we’re saying that, if you follow the above ‘recipe’, you can anticipate the same enviable outcomes as those achieved by Mark McMurtry in his research trials – and subsequently by Boone Mora in his successful USDA-sponsored commercial trial.  Indeed, since Mark never set out to optimise anything (that wasn’t the purpose of the trials), it’s quite possible that you will exceed his outcomes.

The iAVs Recipe

Essential Equipment:

  • Fish tank

  • Light
  • Fish
  • Plants

Instructions – highly recommended

  • 1:2 fish tank volume to sand bio-filter ratio.
  • Water – adjust pH to 6.4 (plus or minus 0.4) – rainwater is best.
  • Provide at least 12 hours of light per day – more is better – plant species-dependent.
  • Start off with 100 x 15g fish per 1000 litres.
  • Ambient air temperature – plant species/season-dependent in the 15oC – 35oC range.
  • Grow a mixture of greens, legumes and fruiting crops (at least 50%).
  • Feed – according to bodyweght – twice per day – last feed not later than 2:00pm.
  • Irrigation volume and frequency – designed to 2 tank exchanges per day – two hours of pumping – work on 8 cycles per day to establish the duration of each flood cycle.
  • Water Temperature –– 25oC – 30oC.
