The 1Pot XL module is extremely versatile and can be used for a wide range of plant varieties and sizes. The 1Pot XL module is easily extended so many pots can be linked to a single tank, as shown throughout the brochure. The 25 litre pot that is supplied with all 1Pot XL modules enables you to grow large specimen plants. The pot and tray can be easily moved if the plants grow too large and need to be spaced further apart.
