Grow more in the same footprint

More herbs within reach. More greens ready to pick. More growing space without needing a bigger garden.

The 12 Layer FlowGrow system is designed for households wanting greater growing capacity while still fitting comfortably into everyday home life.

Place it in a bright indoor position or sheltered outdoor space and enjoy fresh food growing closer to where you live.

How FlowGrow works

1. Add water + nutrients
Fill the reservoir and mix in your FlowGrow nutrients.

2. Water flows from the top
The pump lifts nutrient-rich water through the internal hose to the flow cap at the top.

3. Roots absorb what they need
Water gently flows down through the tower while plant roots absorb moisture, nutrients, and oxygen.

4. Water returns to the base
Unused water returns to the reservoir to be reused again through the system.

Designed for home growing

  • Easy to get started

    Set it up in under 20 minutes and begin growing from day one.

  • More growing space in one footprint

    Grow a wider mix of herbs, leafy greens, and compact vegetables

  • Reuses water naturally

    The recirculating system continually cycles water through the tower instead of draining it away.

  • Fits everyday spaces

    Designed to suit bright indoor spaces and covered outdoor areas around the home.

Frequently Asked Questions

A few helpful things to know

Is this a good option if I’ve never grown anything before?

Yes. FlowGrow is designed to feel approachable for first-time growers while still supporting long-term growing as your confidence builds.

Many people start with herbs and leafy greens before experimenting with other plants over time.

Where should I place it?

FlowGrow grows best in a bright indoor position or sheltered outdoor area with good natural light.

A sunny window, covered patio, deck, or balcony can all work well depending on conditions.

Can I use it indoors?

Yes, provided the tower receives enough natural sunlight. Bright indoor spaces tend to work best for herbs and leafy greens.

If natural light is limited, compatible grow lights may also help support growth.

Is the pump noisy?

The pump runs quietly and is designed for home environments. Most people describe it as a soft water-flow sound.

How much power does the system use?

The tower uses a small low-voltage pump connected to a 12V power adaptor. Power consumption is very low — typically less than a small household light bulb.

What can I grow in it?

Leafy greens, herbs, strawberries, and many compact vegetables all grow well in FlowGrow when light conditions are suitable.

How long does setup take?

Most home growers can set up their FlowGrow tower in around 15–20 minutes.

The system is designed to feel manageable from the start, with simple assembly, guided setup, and minimal tools required.

Once assembled, just add water, nutrients, seedlings, and place your tower in a bright spot to begin growing.

Can I extend my tower later?

Yes. FlowGrow extension sections are available separately if you’d like to expand your growing space over time.
