D.C. Are any of these water quality sensors available for purchase now? We are in the process of making a proposal to the local school here for a small aquaponics system and would like to include remote monitoring Would love to include some or all of what you are working on as an initial/beta tester. I think we might be able to include them in the proposal but not implement them for a few months/early next fall if that would make it more feasible to incorporate them in the project.

Shanghai. Sure! Let me arrange that and make the kit available next week or two? We will also guide the students into how to build and program the system.

D.C. So could we purchase what’s available now (and make allowances in the budget for the ammonia and nitrate). It would be great if the students here could be participating (by using the sensors) in the progress of the project. Perhaps with a couple of Skype/Google Hangouts with you/your team.

Shanghai. We are still working on ammonia and nitrate. We have ph, orp, water temp already.

Medium System Size Options Fall 2013

Option #1) Aquaponics system with two grow beds (each bed measures 4 ft long X 3 ft wide - total of 24 square feet), which will hold around 100 plants at any given time. Given a 50-day grow cycle (optimistic, but doable) for salad greens, this could yield as much as 2 plants per day for harvest. This system will require a 180 gallon fish tank (not 55–75 gallons, as I originally showed on the sketches - miscalculation on my part).

Total cost estimate: $4,468

Option #2) Aquaponics system with one grow bed, same as described above. One grow bed will hold 50 plants, so potentially 1 plant harvest per day if growing salad greens. This system will require a 75 gallon fish tank.

Total cost estimate: $3,174

Option #3) Hydroponics system with two grow beds, same as described in #1 above. This system will not require a fish tank.

Total cost estimate: $2,945

For your reference, I am including a link to (in my opinion) the best commercially available small-scale aquaponics system that compares in size to the first system I propose (24 square feet of grow space). Note that the cost shown at the link does not include accessories, lights, or even stands on which the system will be held, etc. - you can see those costs by scrolling down on the options shown.

Our estimates do include those accessory costs. And the primary difference in our set-up would be that it is customized to your space, and our fish tank is a glass display, rather than an opaque tank below the grow beds (not for display). Another great added benefit is that we will be there the whole way, to coach you through the process, and be very supportive.

I do not have any recommended hydroponics systems that would compare to ours, but I imagine the costs would be along the same lines as the aquaponics system referenced above.
