Hydroponic Growing Guide for NZ Homes
Learn how it works, what to expect, and how to get the most out of your setup.
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 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, but it’s 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 & nutrients.
FlowGrow uses a two-part nutrient system designed for home growing.
What to expect as you grow
Growth doesn’t happen all at once, it builds over time.
- Early weeks → slow growth
- Mid stage → visible growth
- Later → regular harvesting
Growing through the seasons
Hydroponic growing is consistent, but still influenced by natural light.
- Summer → faster growth
- Winter → slower, but still active
Keeping things running smoothly
Most of the time, your tower just does its thing.
Your role is simple:
- Check water & Nutrient levels
- Top up as needed
- Harvest regularly
