<p>It is not a half baked question at all, Homefire! I am starting to expand my home unit to test sand and misting. I have been posting about a cheap aeroponic design I'm working on (I think it is the mixed or advanced group). I want to confine the experiment to a simpler phase where the plants are housed in 110 mm (4 inch?) pvc pipe. The plants will be in net pots, and the water will be delivered through spray lines housed inside the pipe.</p>

<p>For sand (which has a slow drainage time) and aeroponics / mist ponics though, IMO, there will always be the constraint of mineralization and biological filtration requirements though. I still think the fish tank water will have to be turned over fast enough to maintain water quality, and that there will have to be adequate surface area somewhere to trap solids, provide a habitat for bacteria and worms and run the chemical processes we need. You are correct though in your thinking that if we build systems to use misting, we should be able to get very efficient plant growth, which is what is drawing me to experiment. I picture my home unit having a "core" of a fish tank and gravel beds, and then peripheral sand beds and aeroponics where most of the crops will be housed. </p>

<p>I need to bring things like filters and solids removal into place to get a very clean line of water for the spray line, but as I am not discarding my gravel core, I am still using all my solids in the system.</p> Your comment reminded me abou…tag:aquaponicgardening.ning.com,2011-05-04:4778851:Comment:1041312011-05-04T05:35:50.162ZKobus Joostehttps://aquaponicgardening.ning.com/profile/KobusJooste
Your comment reminded me about something really important to me right now. South Africa is in dire need of this "food revolution", but typically lacks the "grow it in the urban environment" mentality. There is also great problems with planning and sustainable use issues that can only be addressed by going back to schools and starting with the children. Not saying that it is not worth trying to get some support out of the adult population, but lets learn from the marketers and start…
Your comment reminded me about something really important to me right now. South Africa is in dire need of this "food revolution", but typically lacks the "grow it in the urban environment" mentality. There is also great problems with planning and sustainable use issues that can only be addressed by going back to schools and starting with the children. Not saying that it is not worth trying to get some support out of the adult population, but lets learn from the marketers and start establishing sustainable urban agriculture as a conspicuous part of the new urban lifestyle. Adults interested in the concept will show up, but hopefully the next generation will take growing their own food as "for granted" as this generation is with buying terrible warehoused stuff.

<p>Hi Kobus,</p>
<p> </p>
<p>Speaking of media and experiments, you embolden me to ask a half baked question. Do you know of anyone who has succeded with large scale Fog Ponics or Mist Ponics? Just off the top of my beginer's head it seems atractive;</p>
<ul>
<li>No grow media needed.</li>
<li>No timers, siphon valves or index valves.</li>
<li>Plenty aeration.</li>
<li>Tiny fraction of water volume needed. (could you serve much more grow space / fish or humonia input)</li>
<li>Simplified…</li>

<li>Simplified plumbing, containers don't have to hold head pressure.</li>

<p>One would need a very good filter system to keep fog heads from clogging.</p>

Great point Kobus. I feel like we are on the begining of a food revolution that will spark the interest of the next generation as a way to farm that is fun to the younger crowd. Think about it, you can grow food in town and its all organic and not get your hands dirty. Or too dirty haha. This will bring food back to the population in the next ten years Im sure. Every kid I show this to is almost always over the top excited about the concept.
