Auto Top-Up Kits product details:
Auto top-up kits automatically top up nutrient reservoirs allowing you to leave your plants unattended for longer periods.To use these kits all you need to do is buy a big reservoir or water butt and set it up so it is above the reservoir you want to top up and then fit the Auto Top Up kit which comes with very easy to follow instructions. Top-Up kits incorporate a simple float switch that keeps your system reservoir at the maximum level as long as there is water in your main reservoir.
If you're planning on operating an Auto Top-Up system its very important that you include an air pump and stone of some description to keep your solution fresh and prevent it from going stagnant.
