A popular reservoir barrel that is the same type used to create the 6 Pot IWS Flood System. Very hard wearing and ideal for large nutrient quantities, the Space Sava Water Butt has a capacity of 100 Litres, only takes up 40cm x 40cm of floor space and stands 94cm tall (125cm including optional stand). Where possible we recommend locating it outside of your grow room to help keep nutrient temperatures cool.
