Water Quality: Nutrients, pH, solids

How do you ensure a good match between stocking density and crop production? *
I use the widely accepted formulas that have been scientifically proven by the aquaponics community
Please describe how you design and operate your system to provide biofiltration that corresponds to production of fish waste and crops. *
I use the widely accepted formulas that have been scientifically proven by the aquaponics community and we test our water weekly
Do you ever add supplemental nutrients? If so, what materials or products have you used? List ingredients and product names. How much of these do you use? How frequently? *
In instances where plants show iron deficiencies we have added cleated iron to raise levels. We use the amount recommended by the aquaponic supplier that manufacturers the product.
Do you use worms in your system? *
What steps do you take to ensure worms do not introduce pathogenic bacteria to your system? *
Yes - upon receiving worms we isolate them and feed them
What materials do you use to buffer pH? *
We have used potassium and calcium carbonates to raise pH levels over a 3 day period to 6.8, as measured by our electronic and reactant test.
What methods do you use to prevent the build up of waste solids in your system? *
We have a swirl filter on our 200 gallon system. We clean all our pumps and tubing plumbing on at least a monthly basis, and sooner if we not build-ups in the tanks or plumbing
Please indicate how often you monitor each of the following:
pH? *
Daily and weekly
Temperature? *
Dissolved oxygen? *

What growing media do you use? Please list the ingredients. *
Coco coir
Do you use any chemically-treated or genetically modified seeds? *
Do you purchase some or all of your transplants? *
Describe your primary insect pest challenges AND methods of prevention and control. (Do not answer "none". You MUST indicate actual pest challenges or LIKELY challenges, and you must ALSO indicate how you manage or how you would manage them. If you indicate a product, also specify how often it's used.) *
We use sticky fly traps to deal with white flies and other flying pests. We also use sticky traps to control water bugs.
Describe your primary plant disease challenges AND methods of prevention and control. (Do not answer "none". You MUST indicate actual disease challenges or LIKELY challenges, and you must ALSO indicate how you manage or how you would manage them. If you indicate a product, also specify how often it's used.) *
We at times will see downey mildew. We try to reduce the occurrence through controlling humidity levels; using seeds that are resistant; and eradicating infected plants
CNG certification requires the use of certified organic or Certified Naturally Grown seeds whenever available. Please indicate the suppliers from which you source - or will source - your seeds if your application is accepted and you continue the certification process. *
We buy our seeds from Johnny’s Seeds and use only organic seeds for the majority of our purchases
Please indicate, by entering your initials, that you understand that CNG strictly prohibits the use of chemically treated or GMO seeds. *
Please indicate, by entering your initials, that you will as a general rule purchase organically grown seeds, AND that you will only purchase conventional seed when the variety you wish to grow is not available in certified organic or CNG form. For each variety purchased in conventional form, you will identify (and keep records of) at least three commercial organic seed suppliers who do not carry that variety. *

Fish Management

We do not offer certification for fish, but do set some limited standards for fish management where they might affect the produce and or quality of life for the fish.

Do you use black soldier fly larvae or duckweed as supplemental feed? *
Do you use any supplemental feed besides BSF larvae or duckweed? If so, describe it here, and indicate how you protect against contamination of your system. *

Protecting Against Contamination

Is your operation partially or entirely INdoors? *
What are the nearby land uses? Are there any that might pose risks of contamination? *
Our operation is entirely indoors
How does your ventilation and air filtration system prevent possible contamination? *
Our ventilation comes from rooftop HVAC systems, ductless splits, ventilation fans, and a roof mounted exhaust fan
Do you share space (including fish tank, seedling starting, or plant production space) with other producers? *
Is your operation partially or entirely OUTdoors? *

Waste & Energy

These questions will not determine certification status, but are intended to encourage producers to review our recommendations in these areas and to give credit to producers who have made investments in the sustainability of their operation.
How do you dispose of fish solid wastes? *
We dispose of the solid fish waste in our dumpster. However we have plans to begin to compost and add the waste there.
When necessary during system change over, how do you dispose of nutrient-rich water? *
We provide soil growers with our nutrient rich water.
What measures have you taken to conserve energy, improve energy efficiency, and/or use energy from renewable sources? (This could include system design, siting, insulation, crop and fish species selection, and more.)
All of our smaller systems and germination racks use fluorescent lights that are HO T5, thereby limiting energy consumption. We keep grow room doors closed to limit loss of conditioning, as well as, infiltration of pests.

Inspections & Networks

A core requirement of CNG certification is the on-site peer-review. Getting this completed is facilitated if you're a part of a network of aquaponics producers who might serve as your inspector. Are you a part of a network (informal or formal) of aquaponic producers in your geographic area? *
Tell us about it. Does it have a name? Roughly how many members, and what geographic area does it cover? *
Within Western TN, I am associated with a farmers market, Cooper-Young with approximately 20 producing members and a food co-op, Tri-Delta Agriculuture Co-op that has 12 producing members

I will not label, or in any way lead consumers to believe that produce not raised in accord with CNG standards is Certified Naturally Grown. *
I understand that I have to complete at least one Inspection(s) of another CNG aquaponic producer in my area each year, if there is one within a one hour drive. *
I understand that the inspection I conduct will NOT be of the same producer that inspected me. *
I have reviewed the Certified Naturally Grown aquaponic certification standards, I understand them, and I will abide by them. I understand that if I have any questions I may contact CNG for clarification. *
You may use this space to tell us anything else you think we should know about your operation.
