Does the Aquavalve 5 go on top of the gravel bed along with smaller pots, ie water level max is 20mm above top of gravel? Or should valve be on surface of tray, ie surrounded by gravel so plant roots have to go into gravel for water?
Hi There…. Please place the AQUAvalve and cover directly onto the tray not the gravel…. The AQUAvalve must be placed on a flat surface in order to perform correctly, please also ensure the tray is level, use a spirit level to check
