GREENHOUSE BUILD

IN PROGRESS

Backyard greenhouse with full automation. Start with a structure, end with a self-watering, climate-managed growing system.

Geodesic dome hub kit — components laid out in the box

MATERIALS STATUS

Timber sourced

Geo kit ordered — buildwithhubs.co.uk

Plastic wrap

Still need to sort this

Frame assembly

Automation layer

AUTOMATION PLANS

Arduino + relay board as the control layer
Exhaust fan — temperature triggered
Mini solar panel + battery — self-powered off-grid
Misting and watering mechanism on a schedule
Eventually: computer vision to monitor plant health and trigger actions automatically
