Great post I am subscribing to this thread because I have been messing with compost
tea since day I built my first hydro. The problem I had was (and they told me this)
I am trying to feed plants a tea that should be used with soil not water based system.

Hydroponic based on water and nutrient solution
Aquaponic based on soil (I believe is correct?)

Now you are talking about a system needing the elements based on a soil grown
produce (but I know it is not soil). Is that that correct? If so then why not use a F&D
system using compost tea? Doesn't the bacteria still need ammonia?

I was also told that compost tea is not able to sustain microbial life in water without
a food source such as "molasses" and oxygen to keep them alive. I wanted to be able
to grow food using my own tea that was what I was after anyway. I can make great tea
right now with more than one brewer I built and we spray it or use it as soil drench.
