Hydroponic Growing Guide for NZ Homes
Learn how it works, what to expect, and how to get the most out of your setup.
Growing your own food at home doesnβt need to be complicated.
With a hydroponic tower, youβre simply growing plants in water instead of soil, using a consistent flow of nutrients and light.
How hydroponic growing works
-
Water + nutrients
Plants are fed through a circulating mix of water and nutrients.
-
Light drives growth
Natural light powers how fast and how well your plants grow.
-
Roots absorb what they need
Without soil, plants take in nutrients directly from the water.
-
The system recirculates
Water flows through the tower and returns to the reservoir to be reused.
What you can grow
Most people start with simple, reliable plants that grow quickly and consistently.
- Leafy greens
- Herbs
- Strawberries
- Cherry tomatoes and more

Getting the position right
Where you place your tower makes a big difference β but itβs also easy to adjust.
With wheels on the base, you can move your tower to follow the light or shift it between indoor and outdoor spaces.
Most setups work best in:
- Bright indoor spaces
- Near windows with good natural light
- Covered outdoor areas

Keeping your plants fed
Instead of soil, your plants get everything they need through water.
FlowGrow uses a simple two-part nutrient system designed for home use.
- Start light (40ml A + B)
- Increase as plants grow (80ml A + B)
