Autopot FlexiTank 100 Liter Reservoir is a collapsible tank for irrigation system in indoor cultivation, designed to store nutrient solution with quick assembly and no tools required. Includes 16 mm tap, opaque body that prevents algae, and external level gauge for watering indoor crops with precision and order.

This modular tank is built with durable technical fabric with rings and legs that provide stability even when fully loaded. The foldable design allows you to transport and store the set in minimal spaces when not in use.
The Autopot FlexiTank 100 Liter Tank features a 16 mm tap ready to connect to main hose, valves, or inline filters; the opacity of the material blocks light to protect the nutrient solution from algae proliferation.
The external indicator makes it easy to monitor the available volume without opening the lid, reducing handling and water contamination.
Approximate dimensions 43 x 75 cm, weight 1.9 kg and finished in blue color to clearly identify the tank inside the grow room. The cylindrical structure optimizes the water column and stabilizes pressure towards timers or irrigation controllers.
Compatible with 16 mm lines and branches to 13/6 mm using adapters, it integrates into drip systems, Autopot, coco, DWC/RDWC with microtube branches and gravity irrigation solutions.
In addition, the FlexiTank family offers capacity alternatives of 25 L, 50 L, 100 L, 225 L, 400 L, 750 L, and 1000 L, facilitating scaling in professional and domestic projects.
With this tank, supply becomes reliable, measurable, and easy to maintain within an online grow shop that prioritizes ergonomics and consistent results.
In grow rooms, tents, or vertical racks, the Autopot FlexiTank 100 Liter Tank stabilizes supply for scheduled irrigation cycles, reduces EC and pH variations, and simplifies nutrient mixing. The foldable format allows the tank to be brought in through narrow doors and assembled directly inside the room, avoiding moving full tanks and spills.

• Store 100 L of water or nutrient solution for drip or gravity irrigation.
• Distribute flow to 16 mm lines, with the option to sector by benches.
• Protect the mix thanks to opaque material that limits algae growth.
• Monitor volume with external indicator without uncovering the tank.
• Simplify maintenance with drain tap for cleaning and solution changes.
Operational advantages:
• Tool-free assembly, ready in minutes.
• Foldable for efficient transport and storage.
• 16 mm tap compatible with standard hose and irrigation accessories.

For a robust system, it is advisable to accompany with:
• 16 mm hose as main line and reducers to 13/6 mm depending on dripper.
• Shut-off valves and check valves to sectorize and prevent backflow.
• Inline filter to protect drippers and solenoids from particles.
• Timers and flow/time controllers to automate irrigation.
• Oxygenators or diffuser stones if higher dissolved O₂ is required.
• pH/EC meters for solution calibration according to crop phase.
1) Unfold the fabric, place rings and legs in the indicated order; place on a level surface.
2) Screw in the 16 mm tap with gasket, without forcing; check for leaks with a little water.
3) Fill with water, adjust pH and EC; add nutrients and mix gently.
4) Connect the 16 mm main line to the tap, install filter and valves for each sector.
5) Purge air and sediments by opening lines for a few seconds; check flow at remote points.
6) Keep lid closed, check level with external gauge and schedule periodic refills.
Technical tips: avoid direct light, perform scheduled solution changes, clean the interior between cycles and use watertight connectors to minimize leaks.
