Oganic Hydroponics

I may have committed a taboo with my last post, I did not intend to advertise a commercial product. My apologies if I did wrong, my intentions were only to provide an answer to a problem.I find these articles and comments to be as valuable as anything on the net and would not like to do anything to break the rules of using them.

There is a commercial product called Planters II that is all natural and has been used successfully to augment fish waste water in aquaculture. It provides bio-active forms of the micro-nutrients Calcium, Sulfur, Magnesium, Cobalt, Iron, Molybdenum, and Boron that, from what I remember reading, were all that were needed as supplements for most heavy feeders like tomatoes.I really think that,as the author stated, a compost tea supplement to the waste water would work as well, just check the nutrients and add whatever is needed in an organic form. The Planters II is made by U.S. Soil,Inc. and has an interesting website that tells the history of this natural mineral deposit product and how it was formed.It is used in soil gardening as well.

The idea that fish may produce growth inhibitors that can affect
plant via the water is very interesting. Perhaps you could try
tadpoles instead of fish. They grow even if there are lots in a
tank, they'll eat small sinking fish pellets as well as mozzie
larvae, and as as I know and have noticed, they don't have growth
inhibitors. If there are too many into one one system they'll just
eat each other. So feed them well. Also, here's a thought- does the
use of commercial fish food negate the 'organic' status of the
resulting veggies if the water is used in your hydro system?
