What is a Bubbler System?
This works on a similar principle to the Rainforest System except that it is slightly more forgiving. If the pump fails in this system the plants will still survive as long as the roots are still sitting in the nutrient solution. The system is very simple. It uses an air pump with air stones, a container with a lid usually a rectangular container of about 45litre capacity. Into the lid holes are drilled to fit small netted pots. These pots are filled with clay pebbles and the seedlings placed in them so the roots are touching the base of the pots. The container holds the nutrient solution and the air pump and air stones continuously agitate the water so it does not become stagnant and at the same time add much needed oxygen. The idea is that once the lid with the netted pots is placed onto container the roots will grow through the pots into the nutrient solution. The roots are thus in water all the time. The potential for root rot is lessened by aerating the water.
