Hydrofarm's Dirt Pot Box offers value and versatility, whether they are used for raised bed gardens or as tray liners for hydroponics systems. Featuring porous breathable fabric, they allow your plants to thrive by promoting exceptional root health and vigorous growth. While these work well outdoors, they also fit standard hydroponics trays for use indoors. The Dirt Pot Box is stronger than similar products, with a PVC frame that supports the entire structure.

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm

RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output
