Aquaponics Plant Growth and Nutrient Cycles
Two beds were planted on the same day. One is thriving. One is struggling. What does the water say about why?
Evidence you will build
- Growth measurement dataset
- Photo timeline
- Nutrient-cycle diagram
- Ecosystem model poster
Why this matters
Plant growth in aquaponics connects transport biology to sustainable kai systems communities are building across Aotearoa.
What you will investigate and collect
You will track plant growth in an aquaponics bed and connect it to the nutrient story the water is telling. What conditions seem to help plants grow well in AwaKai — and which differences between beds matter most. Plant heights or leaf counts on a set schedule, photos of each bed, and the water readings being collected alongside the water-quality study.
- Date and time
- Bed or plant label
- Height (cm)
- Leaf count

Hold a probe at a fixed depth or position match your strongest evidence spots
If readings shift with probe position, fixing the geometry makes patterns interpretable.
