Growth Hormon levels

I'm the past when I had fish I would change out the 1/4 of the water every other week to keep the growth hormone low so the fish would grow faster. Once the water is saturated with GH they stop…Continue

urine powered generator from Africa; can it work chemically with something like struvite?

Started by Tom Cooley. Last reply by Vlad Jovanovic Dec 5, 2012. 6 Replies 0 Likes

My organic chemistry knowledge is too slim and rusty to tell how or whether this urine powered generator from Africa might be able to be combined with aquaponics and/or struvite making, but I thought…Continue

Comment by Derrick Kerr on September 21, 2014 at 9:01pm: If anyone here is in Maryland, I just created a group Maryland Aquaponics for open discussion about the difficulties specific to our area. Please join me and lets talk aquaponics.

Comment by Bob Campbell on February 9, 2014 at 1:46pm: I often supplemented with cheated iron - either FeEDDHA, or FeDTPA.

I understand that Fe2+ is generally created by anaerobic bacteria and held stable by organic acids.

But I read somewhere that bacteria in the guts of worms can also chelate iron, making it available to plants.

I've been unsuccessful in my search for a reputable study, or even a quote from someone such as a Dr. or scientist of agriculture to confirm that worms do in fact chelate iron and maybe even other minerals.

I would appreciate a link to any study that I could quote to either authenticate or debunk this claim

Comment by Chris Carr on January 27, 2013 at 6:38am: Not directly aquaponics but coursera is offering (starting tomorrow) an intro to organic chemistry class, which will later be followed by a part 2 as well as a two part intermediate level.
