Thus, the ultimate solution is quite clear - take a flexible tank. Quick and easy to assemble, it is very tiny when folded up and thus also easy to transport if necessary. The manufacturer of AutoPot thought the matter over and developed exactly such tanks for your requirements: the FlexiTanks. The FlexiTanks are also part of all AutoPot irrigation systems.
Tanks of the following capacities are available: 100, 225 and 400 litres.
