Titan Controls has come out with an all-inclusive Bubble Bucket system. This method of growing is not a new one, people have been making their own DIY deep water culture (DWC) buckets for years. However, this is a nice, affordable, all-in-one kit that takes the time and effort out of piecemeal'ing it. For $35.00, the same price as all of the individual components (dual air pump, air stone, tubing, grommets, fittings, net pot lid, expanded clay pellets, etc.), you can buy one single kit that comes conveniently inside the 5-gallon bucket, with all of the connections in place to add more buckets if you want to.
DWC is one of the easiest hydroponic systems for those who are just getting started with hydroponic gardening. All of the water and nutrients for the plant are kept in the 5 gallon bucket reservoir, an air stone attached to an air pump is oxygenating the solution so you never have standing water (standing water breeds fungus and bacteria that can be very detrimental to your plants, especially their root systems). Your plant is in the net pod lid, with its roots being held in place by expanded clay pellets. Expanded clay holds a very minimal amount of water and your solution will be very aerated, so your plant's roots will have a lot of contact with oxygen. The rate of growth in a system like this is VERY fast, which is the main reason why it is considered a favorite over growing in soil.
