Aquaponics app challange

Brief
Aquaponics is an ancient food production method that combines aquaculture with hydroponics that regain its popularity in the last few years. (ref. 1)

Aquaponics brings us a lot of advantages with respect to the convetional agriculture methods.

On one hand it give us: (ref. 2) on the other hand, Aquaponics, especially in large / commercial scale, requires in-depth knowledge in various fields which probably prevents farmers and communities to adopt it.
 * Significant water saving
 * High utilization of farmland
 * High quality organic yield

Technological brief
The technological goal is to make the Aquaponics knowledge more accessible for the common layman to effectively plan an Aquaponics system, monitor & log its progress & recieve relevant advices on how to operate and mantain it over the time.

The app will offer the following features in its first phase (Cleanweb Hackaton):
 * Aquaponics system planner using pre-defined formulas. (ref. 3)
 * Daily water chemistry cycle parameters logger. (ref. 4)
 * Advisory module that will analyze the daily parametrs input and output relevant advices

Technological constraints
As the app is designed for emerging markets, we are required to use a technology that will allow us to address the widest possible audience with the lowest possible operational costs.

We must utilize cross-platform, open web techonologies for the app frontface, and for the backend development as well, so in the future we will have the possibility to merge frontend & backend to support areas without internet connections.

for the Hackaton
To allow each developer to use its prefferable enviroment, we need an open-source cross platform development technology.

Selected technology
The most suitable techonlogy that meets our constraints as I see it is:
 * Node.JS for backend development
 * MongoDB for our Database
 * HTML4 that can be rendered in older versions of Gecko(Nokia Asha Platform) & Webkit browsers
 * Full stack (JS) will allow us more easily build an offline version

Anyway i would love to hear more ideas
