Description
A light-tight, reflective reservoir that still folds flat
The AutoPot FlexiTank Pro is the upgraded version of AutoPot's collapsible FlexiTank. A white, reflective and light-tight skin keeps light off your nutrient solution – which helps stop algae taking hold – and reflects heat rather than soaking it up, so the solution stays nearer the 18–21°C AutoPot recommend. Inside, concealed supports hold the shape and an anti-tip design keeps it steady when full, while printed internal capacity markings in litres and gallons make mixing nutrient doses accurate. It assembles in minutes without tools, comes with all the fittings including the bottom tap, and packs back down into its slim box when the grow is finished. Use it as the gravity-fed reservoir for an AutoPot system or as a mixing or holding tank in any grow room or greenhouse.
Key Benefits
- Light-tight and reflective: helps keep algae out and the solution cooler than a dark or translucent tank
- Internal capacity markings: measure water and dose nutrients without a separate jug
- Concealed supports and anti-tip shape: stands firm and upright when full
- Collapsible: builds in minutes and stores flat in a 13 cm deep box
- All fittings included: the outlet tap with its click-fit coupling, the fill ports and the internal supports
How to Use
- Position it before filling – on a firm, level base, raised so the outlet is at least 15 cm above the highest AQUAvalve when feeding an AutoPot system. Never drag or move it once it holds water.
- Assemble by hand: fit the outlet tap with its washers, push the support poles into place through the top zip and lock them with their nuts, then – with the tap closed – stand the tank on a smooth, flat surface and half fill it before topping up.
- Connect through the tap's click-fit coupling, which is unchanged from the standard FlexiTank – AutoPot recommend their Click Fit ProFilter on 16mm systems – or to 9mm pipe with AutoPot's 16mm-9mm click-fit adaptor and filter. Filters are sold separately; always run one.
- Fill and mix using the internal markings, then set EC and pH. Refill when about a third remains, with the outlet tap closed for 30–60 minutes so sediment can settle.
- Clean the tank each time it runs low if you feed organics, then empty, dry and fold it away at the end of the season.

Frequently Asked Questions
What is the difference between the FlexiTank and the FlexiTank Pro?
Both fold flat and use the same AutoPot couplers. The Pro adds a reflective, light-tight white skin, concealed internal supports, an anti-tip shape and printed capacity markings inside.
Which size do I need?
AutoPot supply 100 litres with 8–9 pot 1Pot systems (6–9 pots on XL systems), 225 litres with 12–16 pots and 400 litres with 24–60 pots; on easy2grow it is 100 litres for 12 pots, 225 litres for 16–24 and 400 litres for 40–60. A sensible guide if you are replacing or upgrading a system tank.
Can I put an air stone in it?
AutoPot advise against air stones in AutoPot reservoirs because they can raise the pH. A small water pump can be used to keep the solution moving.
