A sturdy aluminum frame supports a tough silver PVC membrane to contain up to 70 gallons / 280L of water or nutrients.

The heat-reflective Mylar® lid is secured with Velcro® for easy access while dramatically reducing the amount of heat transferred to your nutrient solution. Entry and exit holes in the lid allow pipes to run in and out, and can be covered by screw-on caps if not in use.

The ⅝" / 16mm barbed bottom drain tap allows easy and fast draining and is locked in position from the factory to prevent leaks.

Assembled size: 22" / 55cm wide and long, 35.5" / 90cm tall
