Meliflor Flexible Water Tank – Foldable Water Bag for Nutrient Storage

Frequently asked questions

• What advantage does the Meliflor Flexible Tank have over a rigid one?

  Being flexible, it fits into spaces where a rigid tank simply won't fit, and when you're not using it, it folds up and stores away without taking up room. It's also lightweight, so you can move it between rooms with ease. Its seamless construction prevents leaks, so you don't lose any safety in exchange for that flexibility.

• How is it filled and emptied?

  You have a top lid that opens fully via zipper, plus a side tube you can use for filling or as an overflow. To empty it, there's a bottom tap that's quick and convenient. Between the two openings, you cover both filling and emptying without having to move the tank.

• Can I comfortably measure pH and EC inside the tank?

  Yes. The lid's zipper opens all the way, giving you free access to insert your probes and check pH and EC without hassle. That same opening also makes thorough cleaning between cycles easier, which is when it's most appreciated.

• What capacities and sizes are available?

  There are five sizes, given as diameter by height: 100 L (40 x 78 cm), 250 L (60 x 88 cm), 500 L (80 x 98 cm), 750 L (100 x 98 cm) and 1000 L (120 x 88 cm). Measure the available space before deciding, especially the height if it's going inside a cabinet or a low-ceiling room.

• What's the mesh top opening for?

  That mesh opening allows the tank to ventilate while also acting as protection. This way the water breathes without the interior being completely open. It's a practical detail in a tank that's going to be full of nutrient solution for days.

• Is it only for irrigation, or can I use it for other things?

  Besides irrigation in indoor and outdoor grows, it's very useful for collecting rainwater, for events or camping trips, and as an emergency water reserve. Since it folds up and transports easily, it's practical in any situation where you need to store liquid temporarily.
