Holy grail for aquaponic production

Started this discussion. Last reply by john Apr 18. 58 Replies

Which plants are still considered "difficult" or "impossible" to grow in aquaponics?  I have begun a process of trying to design a system that can grow as many different varieites of crop possible. …Continue

I have been made aware of a section in the latest newsletter of an aquaponics trainer making some rather interesting statements around the risk of introducing "deadly" E. coli HO157:H7 into…Continue

Community pages need new management

Posted on November 8, 2011 at 1:36pm 16 Comments

For the last couple of weeks, mounting pressure from family commitments, work and research projects have been taking its toll on my “aquaponics time”.  Recently, these little distractions culminated in the news that a job that I have applied for months ago had finally come through, and that I will be heading off to Cape Town, 800 km from where I live now.  I do not have much time to get all my things in order, and part of what I would like to sort out are the pages that I have started over…

My pick for a commercial fruiting plant in aquaponics: The passion fruit

Posted on October 13, 2011 at 10:47am 18 Comments

Most people interested in commercial aquaponics invariably start looking at potential yields of different crops and then, after a thorough literature search, will discover that there is very little available in terms of potential yields of larger crops.  Stuff like basil, lettuce, tomatoes and cucumbers etc. seem to be written about the most.

 

With the advent of what I consider to be the most likely design for my own use in a commercial environment, namely gravel beds and…

Can "Dirty" water NFT work?

Posted on October 1, 2011 at 6:29am 6 Comments

Time for all the plant experts to wade in please!  I have been tinkering with a number of different media-less / media filled growing configurations of late.  The ones that interested me the most in the end was partly filtered versus “dirty” NFT.  The reason why this has become interesting for me relates back to the type of technology that is required to run these.  Should there be some way of making “dirty” NFT work, then there should be an advantage in trying to understand what I am…

Time to innovate is here

Posted on September 18, 2011 at 2:54pm 6 Comments

There have been a number of articles milling in my head again.  Being a person of above average curiosity in many directions is not always a good thing when there is an internet connection around, as you tend to spend far too much time scratching around in science and technology articles than updating your taxes or whatever else is pending.

 

The joy is when you read three or four totally unrelated papers and get that little flash of insight that allows you to draw new…

Hi Kobus:

Thanks for getting back to me.  To bad about the lack of grow space.  Controlling a piece of the planet is a definite privilege.

Regarding the towers; were the grow pockets too close together vertically or was the 4" PVC tubing too small in diameter hence not enough media?  How much space is needed between towers for proper sunlight?  I was thinking I would like to create a set to keep my indoor brood tanks clean and to grow some strawberries year round.

thanks for any light you can shed on this issue before I spend money (again).

Hi Kobus, I read in one of your posts that you moved to cape town. I also stay in cape town. The aquabug bit me and now I am planning my first setup. But with so many startup failures because of bad planning I want to take my time and learn everything before I start spending money. Would be nice if we can meet up so that I can pick your brain get some knowledge transfer.

regards

jacques

Thanks for the info about the jig for the tower. I like the coffee cup addition.

I'll send you it via e-mail. Is this your e-mail? kobus@seasresearch.co.za

Kobus I typed a research paper for a class and I used some information you have put on this community. Please tell me if I misused or in any way misconstrued your statements. They are about growbed design and duckweed. Also I want to send you the document so I know if I made a mistake, as I'm posting this on the community. If you would like your quotes to be taken away I can revise the paper. Thank you.

Hi Kobus,

Have you got an e-mail address, I will mail some of my questions if you don't mind?
