A key component in the easy2GO kit. 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. Then simply connect the AQUAvalve to a tank, using a length of 9mm pipe and a filter. When making your own hobby systems please ensure that the tray is as level as possible by adding the optional spirit level to the cover. Ensure that the pot size is not less than 5 litres. If you use small pots you will risk the chance of drowning the plants. A small plant in a small pot will not appreciate being sat in deep water as the root system will not be able to breath, this obviously does not apply to bog plants or carnivorous plants. If you intend to grow carnivorous plants using this method please ensure you only use rain water.
