A very interesting article:
http://www.hortidaily.com/arti.....ifferences

... Baras has focused his research trials on Pre-Empt, a plant-derived organic fertilizer which has blackstrap molasses as its major component. He has been comparing organic vs. traditional fertilizers in several hydroponic production systems, including flood-and-drain grow racks, two different nutrient film technique (NFT) systems, deep water culture floating rafts and a ZipGrow Tower system.

“We have successfully grown butterhead lettuce and basil in all of these systems using organic inputs,” he said. “We have several other crops that we are running through these systems in smaller trials, including spinach, cilantro, arugula, strawberries and other lettuce and herb varieties. Most of research is still focused on butterhead lettuce and basil. ...

I found a 2.5 gallon bottle of Pre-empt for $52 at http://hortamericas.com/catalo.....tilizer-2/

Sadly, shipping would be $34.55 -- from Florida.   I'm going to have to find a local source, maybe in Vegas, now that cannabis is legalized and everybody is growing.

I'd also be very interested in Terra Bella, but $225/gallon!  And the microbes would probably die before I used it all. 

I had a $77 order as prices are VERY good at Hort Americas, but shipping would have been $105.77! 

I'm VERY glad to see organic options, just have to get a closer source.

I don't know what to do with the chemical fertilizer water when I'm done with a tub.  Don't want to pollute my organic gardens. Toilet?  Seems like a giant waste.

It sure would be cool to be organic and to be able to use the old water in the gardens.
