Before you assemble
Choose your growing spot before setting up the tower.
Look for:
• Bright natural light
• A stable, level surface
• Access to power
• Enough room to fill, check, and rotate the tower if needed
• A spot where you’ll walk past often
FlowGrow works best in a bright indoor space near a window, or in a sheltered outdoor area with good natural light.
Assemble your tower
Follow the printed quick-start assembly guide included in your box.
You’ll work through these main steps:
- 1 Push the wheels firmly into the reservoir base.
- 2 Insert the base support column into the centre of the reservoir.
- 3 Align the hole in the column with the outlet opening on the side of the reservoir.
- 4 Unscrew the locking nut from the power-cable fitting. Insert the fitting through the reservoir side wall, then refit and tighten the locking nut.
- 5 Attach the hose to the underside of the Flow Cap.
- 6 Set the Flow Cap onto the upper tower stack.

Join the tower stacks, carefully aligning each tab with the matching groove. Press down firmly and evenly until each stack sits securely in place. The fit can feel quite tight during the first assembly. This is normal.
If a stack will not connect, stop and recheck the alignment before applying more pressure. As you join the stacks, feed the hose down through the centre. This is much easier than threading it through the fully assembled tower.
Align each tab with the groove before pressing down. - 8 Lower the assembled tower onto the base support column in the reservoir, guiding the centre hose into place.
- 9 Attach the filter and hose to the pump outlet. Feed the pump power connector through the power-cable fitting installed in Step 4, then tighten the outer cap around the cable.
- 10 Fill the reservoir with water before connecting the pump to power.
- 11 Plug the pump into the timer, then connect the timer to the power adaptor. Set the timer to 1 minute ON and 30 minutes OFF.
Fill your reservoir
Now it starts to feel real. Fill the reservoir with 15 litres of water, then add your FlowGrow Grow nutrients.
Recommended mix
Use equal parts Grow Part A and Grow Part B for established seedlings, herbs, leafy greens and everyday vegetative growth.
For smaller quantities, use 5 ml Grow Part A + 5 ml Grow Part B per litre of water.
- Add nutrients to water, not the other way around.
- Use equal parts Grow Part A and Grow Part B.
- Keep Parts A and B separate until diluted in the reservoir.
- Add Grow Part A first and stir, then add Grow Part B and stir thoroughly.
Add your plants
If you’re starting from seedlings:
- Place seedlings into plant sponges or rockwool cubes
- If using rockwool Insert into net pots
- Sit them into the tower openings
If you’ve already got small plants:
- Gently transfer them into the planting sponges
- Make sure roots can hang down into the tower
The roots will find their way as the water flows.
Turn it on
Once the reservoir has water in it and your pump is connected, you can
turn the system on.
Set the timer to:
1 minute ON every 30 minutes
When the pump turns on, water is lifted from the reservoir up through
the centre hose to the flow cap at the top of the tower.
From there, water gently flows down through the tower and returns to the
reservoir to be used again.
Before leaving it running, check:
• Water is flowing from the top
• The hose is securely connected
• The pump is sitting inside the reservoir
• The power connection is dry and safe
• The tower is standing level
• There are no leaks around the outlet fitting
The first time you turn it on, stay nearby and watch one full cycle.
This helps you see how the system works and gives you confidence that
everything is connected properly.
FlowGrow works by pumping nutrient water up the central hose to the flow
cap, where it spreads outward and cascades down through the tower before
returning to the reservoir.
Your first week of growing
The first week is mostly about settling in. Your plants are adjusting to the tower, the water flow, the light, and their new growing conditions.
Days 1–2
Everything may look much the same. Your plants are settling in and adjusting.
Days 3–5
You may notice leaves lifting slightly as roots begin to adapt.
Days 5–7
New growth usually starts to appear and plants begin to look more at home.
A quick note on light
Your plants need good light to grow well.
Best results come from:
- Bright indoor spaces near a window
- Or a sheltered outdoor spot with sun
Less light means slower growth.
More light means stronger, faster growth.
If your space is low light, growth may still happen, but it will be more gradual. A compatible LED grow light can help if natural light is limited.
Your growing routine
Once your tower is running, the routine is light and easy to follow. Small, regular checks work better than waiting too long between them.
Every few days
Check the water level and top up the reservoir if needed. Make sure the pump stays covered with water.
Once a week
Check plant health, root growth, water level, and general water flow. Add nutrients when topping up larger amounts of water.
As plants grow
Harvest outer leaves as needed, remove any tired leaves, and give plants enough space so light and air can move around them.
Keep Growing
Choose the right pathway for growing supplies, tools, tower extensions and parts.
