1/8" hydroponic drip tubing is the standard for drip irrigation, used to transport water or nutrient solution from a main tube or manifold to a plant site, usually terminating in a drip emitter. This size is normally used in growing commercial plants.
1/8" microtube has very specific uses and a limited flow rate. The distance this tube can run is limited to 5' if coming off a dripper and 10 ft if coming from a 1/2" or larger poly drip tube at 25 PSI.
