The Bubbler method is a easy way to step into hydroponics, it is very cheap to set up but requires constant monitoring.

The plant roots are feed via a nutrient solution which is mixed by bubbling air through it with the use of an air pump and air stone. The water nutrient solution should be at a level which is high enough to wet the air stone. Once the plant has developed a good root system the water level can be lowered enabling some of the roots to hang in the air between the net and the bucket. Air needs to get to the submerged roots constantly meaning that the air pump will need to left on constantly, otherwise the plants will be starved of oxygen.

Generally you will need a separated bucket for each plants otherwise the root system will cover the air stone preventing it from aerating the water and the plant will die.

The Bubbler system needs constant attention as plants take different amounts of water and nutrients from the mixture resulting a ratio that could poison your plants and dry them out. Constant checking of CF and PH of this water is essential for healthy plants.

Plants grown by using the Blubber system will need support and this system is not very suitable to growing large plants.
