So I think I would just start by getting a ton of the smallest fish I could and let them soil the water up for a month or so. Then go from there.
BTW. You don't need a degree in anything to know how to do something. If a person knows theory of knowledge and has mastered scientific method. There is really little one can't learn to an expert degree. Quality of source becomes the real issue.
I live near an organic hydro lettuce farm.. I was talking to the head of operations the other day, and he was educated by Dr Elaine Ingham, in a simple seminar.. It is false to say that organic hydro cant be done in a commercial operation.. And with lettuce.. People can be taught the organic techniques.. they are however a bit more complicated.. PH pen to be replaced by a microscope.
And many are missing alot of knowledge too, it does not have to be aquaponics, the commercial operation I know is using nutrient teas via various composting methods using hydroponics in NFT to feed the lettuce crop. Bacterial action creates salts,..
But we all have to realize that we still need things like compost heaps, vermicomposting to provide the extracted nutrition for the crops. We still need piles of "dirt" or waste for this operation. Nitrifiying bacterial action creates salts..
If we think about it, a small cannabis grow could actually remove waste from the environment, by recycling kitchen waste or other various bits of paper or trim. I"m not guessing here I'm telling you, recycling waste from your kitchen or whatever sources and into your cannabis grow is cheaper than buying nutrients.
I am not against hydro in any way, but you have to have very specific needs or conditions to grow hydro. My mother plants grow in DWC. But if I need pollen, they grow in dirt, the microbes make it simple to take care of.
Keep it simple, and remember.. better, is the enemy of good.
