The Logbook

A self-sustaining system is not declared — it is built subsystem by subsystem, with the data that each stage produces. The nodes of this series document that process in real time: what works, what fails, and what is still a hypothesis.

Before any financial model of a project that integrates biology, construction, and technology: does each subsystem have its own cycles and restrictions documented independently before modeling the complete system? If the answer is no, the model will be as optimistic as the first one that is abandoned after a week.

If each subsystem of the farm —meliponary, solar, water, agroecosystem— is an instrument of an orchestra, Home Assistant with InfluxDB and Grafana is the score that allows us to see, for the first time, how they all sound together — not just listen to each instrument separately.

This node develops the three techniques that the Iwagé farm mixes to solve both challenges — the Provençal/Candian well as a passive geothermal exchanger, the airlocks and thermal mass of the Earthship design, and odor control through carbon-nitrogen ratio already applicable to the dry toilet.

This node closes the complete circle: how real capture is sized, what the Colombian regulation says exactly about reusing water, what domestic habit change—not just plumbing—makes it possible for that cycle to work, how the sun itself enters the system as a heater and disinfectant, and why the legal distinction between "recirculating" and "reusing" determines whether a project needs prior environmental processing or can operate without it.

This node explains how to properly size an off-grid system for a farm with automation, what Law 1715 says exactly about each of its four benefits, where the real risks of misapplication lie, and what it means.

This node consolidates the complete regulatory map of the Iwagé self-sustaining system in one place, adds the missing pieces — rural land use for agrotourism, beekeeping registration with the ICA, and the actual sanitary regime of honey — and shows in what order and before which entities each procedure runs.

Defines why the climate of Ibagué requires a calendar different from any generic planting guide, how three seemingly distinct cultivation systems —wicking bed, vertical hydroponics, and permaculture raised beds— complement each other instead of competing, and how this subsystem directly receives the inputs that the hydrological cycle and the bio-refinery already produce.
