method of plant propagation where the roots are suspended in nutrient which have rich in oxygenated water. It is essentially a top fed deep water system which pumped from the reservoir to the top of the roots. Thus‚ it helps significantly in enhancing growth in the first few weeks. This technology has advantages when being set up in the process of experiment. The roots get easy access to water from the beginning.

Keizer‚ it was theorized that one type of aquatic plant may be a better competitor for sunlight than another plant that is more of a bottom dweller. They argue that “P. pectinatus and C. aspera have different growth forms and the canopy forming P. pectinatus may be a better competitor for light than the bottom-covering C.aspera.” to support this first argument. In addition they also put forth a second argument in that the bottom dwelling aquatic plant may‚ in the long run‚ be a better competitor in
