Types
Regular hydroponics is often operated using NFT (Nutrient Film Technique). This uses a shallow (film) of nutrients; about 1-2mm deep. Flat-bottom rain gutters can be used as growing channels.
Regular drip lines can be a low-cost/uncomplicated alternative if you do not require the advantages of a hydroponics system and just wish to use a system to water your plants indoors. Fertilisation can then be done manually.
Making the nutrient solution
One of the main difficulties with X-ponics systems is how to obtain the nutrient solution. In developing contexts, these may be difficult to come by, and are often also too expensive for most people in the developed world. However, the nutrient solution can also be made DIY using either liquid fertiliser of a wormery ("worm tea") or from comfrey concentrate/tea[1].
