- Have you ever been certified in the past? *
- Have you ever been denied certification? *
- How did you hear about Certified Naturally Grown? *
- I've known of CNG for many years and am very happy to have aquaponics included in the CNG family.
- Please check all crops you grow in your aquaponic system. *
- Please specify what other crops (if any).
- micro greens
- Please check all markets you grow for (this will be displayed on your farm profile to help potential buyers find you). *
- Please specify what other markets (if any).
- local schools and the county senior nutrition program
System Design and Management
- Please indicate what type of system you use (for hybrid systems, check all that apply): *
- If you indicated you use an "other" system type, please specify what other type of system you use here.
- We use our patented Clear Flow Aquaponic SystemsÂ® with ZDEP (zero waste/extra production)
- If you use wicking beds, describe how the water his handled after it is used in the wicking beds. Does this water recirculate? If not, how is it disposed of?
- What materials are used for root support, growing media, tubing and pipes, tanks, troughs, and other materials that come into direct contact with system water? (check all that apply) *
- Are there any other materials you use in your system that are not listed above? If so, please indicate them here.
- potable water grade liner NSF certified PVC pipe
- If you use soil or compost in your system, where is it used? Is it used only in the dead-end portion, or also in in the recirculating sections of the system?
- no soil or compost
- If you use compressed grow plugs, what is (are) the product/s name/s? Have you been able to confirm with the supplier that it/they do not contain synthetic nutrients?
- no compressed grow plugs we use rockwool
- If your system contains cement, does it come into direct contact with the water? Please describe how cement is a part of your system.
- no cement
- If you use wood in your system, is it treated wood? Does it come into direct contact with the water? Please describe how wood is a part of your system.
- we use cedar wood stands, but there is no contact with system water
- If your system includes IBC totes purchased used, have you been able to confirm with your supplier that they were used only for food grade uses? If so, how have you confirmed this? If not, how do you intend to confirm this?
- no IBC totes
- Please note that while IBC totes can be grandfathered in when they're in already in use at the time CNG certification is sought, CNG standards prohibit the introduction of IBC totes once CNG status is obtained. Please indicate that you understand this restriction on IBC totes by checking the box here. *
- Does water circulate at a rate sufficient so that the water volume of the fish tanks(s) recirculates each hour? If it recirculates at a lower rate, please explain. *
- Briefly describe how your system achieves appropriate aeration. *
- We aerate 24/7 with blowers and air diffusers in the fish tanks, degassing tank and raft tanks
- Briefly describe how your system achieves appropriate degassing. *
- we have a separate vessel for degassing. It is aerated 24/7
- Does your system include any of the following: roofing materials, recycled plastics, or plastics that contain BPA? *
- CNG standards vary according to water source. Please indicate below ALL water sources you use for your aquaponic system, and answer the corresponding questions.
- Do you use Municipal water? *
- Do you use well water? *
- What are the ground water contaminants of concern in your region? *
- none known
- What experts did you consult to determine contaminants of concern? *
- well drillers, county data
- Have you tested your well within the past year, and if so, what were the results? *
- We send regular system water samples for analysis to Micro Macro, and agricultural lab. The most recent was: 1/29/16. The test included: Nitrate-Nitrogen, Ammonium-Nitrogen, Phosphate, Potassium, Calcium, Magnesium, Boron, Copper, Iron, Manganese, Molybdenum, Sodium, Sulfate, Fluoride, Chloride, Carbonates, Bicarbonates, pH, EC, Aluminum, Iron, Manganese, Zinc, Copper, Zinc, and Molybdenum, Alkalinity(mg CaCO3/liter). We don’t have other known “contaminants.” We did have our county water test in 2009, with no issues or contaminants. We also, in collaboration with University of Wisconsin-Stevens Point, have our system water, source water and plants analyzed by UWSP microbiologist, Dr. Matt Rogge. The results are an excellent demonstration of the pureness and safety of the food in our systems and the data and results of this research will be published later this year. The most recent samples were taken in January, 2016.
- Are you willing to start testing annually? *
- Do you treat or filter the water before adding it to the system? If so, what methods are used? *
- yes, we have a water purification system to eliminate potential biological contaminants. The well water flows into a particle filter to remove particulate matter, followed by a chlorine injection system to purify and then a chlorine removal filter. This is a process very similar to municipal water treatment, but we remove the chlorine as the last step, making the water ready to go into our aquaponic systems.
- Do you use rainwater? *
- Do you use surface water? *
- If you use a water source that is not named here, please elaborate.
Water Quality: Nutrients, pH, solids
- How do you ensure a good match between stocking density and crop production? *
- We have developed proven, science-based formulas over the past 20 years. Our fish stocking is designed to support a specific vegetable crop load.
- Please describe how you design and operate your system to provide biofiltration that corresponds to production of fish waste and crops. *
- We have nitrification tanks and mineralization tanks, sized for our system. And, we allow nitrification to happen throughout the system. We monitor ammonia and nitrite to make sure the levels are safe and we consistently have safe levels.
- 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? *
- chelated iron, as needed.
- Do you use worms in your system? *
- What materials do you use to buffer pH? *
- Occasionally, we raise pH with potassium hydroxide and calcium hydroxide. However, pour water is quite stable and this is not frequently needed.
- What methods do you use to prevent the build up of waste solids in your system? *
- We removed the settable solids via clarifiers. In our patented ZDEP® systems, the waste is collected from the clarifiers, processed and the fresh, nutrient-rich water is returned to the system.
- Please indicate how often you monitor each of the following:
- pH? *
- Temperature? *
- Dissolved oxygen? *
- 1 x/week
- Ammonia? *
- 1 x/week
- Nitrites? *
- 1 x/week
- Nitrates? *
- 1 x/week
- Use this space if you'd like to share additional information about your water quality and monitoring practices.
- Where listed as 1x/week, that is our standard protocol. If, based on observation, we see the need, we will test more frequently.
Seeds, Transplants, and Crop Health
- Do you grow some or all of your own transplants? *
- What growing media do you use? Please list the ingredients. *
- Rockwool cubes, 1.5"
- 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.) *
- Thrips, aphids and whitefly. We have strict bio-security protocol and insect screening for prevention. We monitor and scout weekly to look for pest problems. We use biological control for pest insects.
- 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 occasionally have powdery mildew. Response: Remove effected plants; lower humidity WE really don't have other plant disease issues in our controlled environment greenhouse
- 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. *
- Johnny's Seeds Seed Savers
- 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. *
- 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.
- Does hormonal sex reversal treatment ever occur on-line / within the recirculating system? *
- Please describe the practices you use to prevent and treat fish disease.
- We have strict bio-security as a preventative measure. If we have to treat a fish, we move it to a separate hospital system. To date, we have never treated with anything other than salt and temperature manipulation.
- Have you ever found it necessary to use antibiotics? *
- Please describe what kind of fish feed you use. Is it organically grown? (For aquaponic produce certification CNG standards do not require that the feed be organically grown, but we are interested to know what producers are using and to give credit to any producers who may be using organic feed) *
- We feed the Rangen XG360, which is free of terrestrial animal bi-prodcuts
- 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? *
- No. We are on 12 acres. there are homes on the adjacent properties. We are not near any manufacturing or industrial pollutants.
- How does your ventilation and air filtration system prevent possible contamination? *
- We are in a controlled environment greenhouse. We bring in fresh air for ventilation.
- 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 have zero waste in our systems. All fish waste is 100% utilized for plant growth.
- When necessary during system change over, how do you dispose of nutrient-rich water? *
- Our patented Clear Flow Aquaponic Systems® with ZDEP® captures and processes system wastewater, bringing fresh nutrient-rich water back into the main system and utilizing the remaining water and solid waste to grow additional crops in our Living Filter beds. This eliminates the need to discharge water from the aquaponic systems. Drain water from sinks and washing in the greenhouse goes into one of two septic tanks on the property.
- 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.)
- 1/3 of our greenhouse is insulated and covered with metal roofing. The north end is insulated. The remaining area uses dual layer polycarbonate, which is energy efficient. We use a wood boiler for heating system water. We incorporate insulation everywhere we can.
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? *
- We have a network of growers using our Clear Flow Aquaponic SystemsÂ®. There are about a dozen within a couple hour radius, and then we have many more throughout North America. I believe most, if not all, will want to become certified.
- I understand that only the produce, NOT the fish, can be labeled and sold as Certified Naturally Grown. *
- 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.
