Grow1 Collapsible Water Tanks are here to revolutionize your water storage needs! Made of a flexible, heavy-duty, PVC material, these water tanks are capable of collapsing to provide an easy means of cleaning and transportation after use. Grow1 Collapsible Water Tanks are a great alternative to cumbersome, solid, space-consuming reservoirs that are difficult to transport and relocate. Each Grow1 Collapsible Water Tank includes a pre-installed removable top straining screen, 3/4" tap and valve fitting, 3/4" fill fitting, and a 3/4" male connector.
