Project overview

The Urban Greenhouse Challenge required a vertical farming concept that could produce reforestation seedlings in urban settings. Crop Urbanis led agronomy design and growth modelling.

Challenges & approach

  1. Conifer seedlings need specific photoperiods, humidity and nutrient regimes for viability.
  2. Space and resource efficiency were critical to competition criteria.
  3. Prototype required documentation enabling handoff to partner teams for execution.

Our contribution

  1. Designed multi-tier climate zones with precise lighting and humidity control for conifer stages.
  2. Modelled energy and water use, optimising rack layout to meet competition sustainability scores.
  3. Produced a full concept deck including SOPs, BOM, and growth curves to guide implementation.

Inline FAQs

Can this prototype adapt to other tree species?

Yes—lighting and nutrient recipes are modular; the deck includes adaptation guidelines.

How is the prototype powered sustainably?

Energy modelling integrates solar supplement options and heat recovery to meet sustainability targets.
