Services

Agronomy, hydroponics, monitoring, CAD and practical growing-system support

Charles combines plant and soil science, hydroponics manufacturing experience and practical technical ability. The common thread is making growing systems easier to assess, plan, monitor, document, troubleshoot and operate.

Agronomy & Crop Support

Crop observation, soil or growing-media interpretation, nutrient review, irrigation thinking and practical second opinions for growers.

CAD & Design Support

Archicad and FreeCAD support for layouts, fixtures, residential design references and build ideas that need to be easier to inspect.

Crop Data & Workflow Tools

Dashboard prototypes, database-aware workflows and simple tools for crop data, sensors, chemical records and operator-friendly decision support.

Systems & Cloud Operations

Practical desktop, server, DNS, Cloudflare and private-service experience for projects that need reliable access and troubleshooting.

Capability

Plant knowledge backed by practical technical support

The strongest fit is work that sits between crops, hydroponic systems, controlled environments, monitoring, controls, CAD support and simple operational tools.
