Low Pressure Aeroponics (LPA)
Definition - What does Low Pressure Aeroponics (LPA) mean?
Low pressure aeroponics (LPA) is one of two types of aeroponic growing systems. In an aeroponic growing system, plants are not grown in soil. Instead, they are grown with their roots hanging suspended in air while a nutrient solution is delivered to the roots as a mist. Low pressure aeroponic systems deliver the mist to plant roots at a low pressure with large droplets.

LPA systems are some of the most popular aeroponic systems as they can be easily and cheaply made. Many indoor gardeners often build their own variations of an LPA system. Most LPA systems generally run 24 hours, seven days a week, constantly wetting plant roots. However, they are not as efficient as high pressure aeroponic (HPA) systems that use a finer mist.
Low pressure aeroponic systems can be built from easily acquirable tools and parts. Many homemade LPA systems employ miniature sprinkler heads and some PVC piping or tubing. These small homemade systems, when made efficiently, can be good for cloning plants, flowering plants before planting them in a more traditional medium, or for growing a small crop of vegetables inside the home.
