AQUAvalve Cover The AQUAvalve cover, when used in conjunction with the AQUAvalve allows the grower to create their own basic, but very effective, hobby system.
All that is needed is a flat tray of any shape or size.
The user then simply places the AQUAvalve in the tray and places the AQUAvalve cover over the top of it.
The cover is made of a heavy composite material, so there is no need to place a weight on top to hold it in place.
