Common questions, answered simply

A few helpful things to know

How does a FlowGrow tower actually work?

A FlowGrow tower circulates water from the base up through the centre, then lets it gently flow back down through the roots.

As it moves, it delivers water, nutrients, and oxygen to the plants. Any unused water returns to the reservoir and is reused again.

Once it’s set up, the system runs on a timer and quietly takes care of itself in the background.

Do I need soil to use a FlowGrow tower?

No, there’s no soil involved.

Plants sit in small support sponges while their roots grow inside the tower where the water flows through.

It’s a clean, contained way to grow, with no digging, no heavy pots, and no mess.

Does FlowGrow need direct sunlight to work?

FlowGrow needs good natural light to grow well.

A bright indoor space near a window, or a sheltered outdoor spot with consistent sunlight, will give the best results.

If light levels are lower, growth may slow down. Grow lights can be used if needed, but many people simply use the brightest spot in their home.

What can I grow in a FlowGrow tower?

FlowGrow works best with everyday plants you’d use in your kitchen.

Leafy greens, herbs, and compact vegetables all grow well. Things like lettuce, basil, spinach, cherry tomatoes, and chillies are great options.

If you’re just getting started, herbs and leafy greens are the easiest and most rewarding place to begin.

How long does it take to set up a FlowGrow tower?

Most people have their tower set up and ready to plant in around 20 minutes.

The process is straightforward, with no complicated parts or tools required.

Once it’s running, it becomes something you check and enjoy rather than something you need to manage closely.

Is FlowGrow suitable if I’ve never grown anything before?

Yes. FlowGrow is designed to feel approachable from day one.

You don’t need prior experience or technical knowledge to get started. Once it’s set up, the system settles into a rhythm and becomes part of your routine.

It’s often more about enjoying the process than learning something complicated.
