REVERSE OSMOSIS
Osmosis refers to the diffusion, or flow, of liquid moving through a
selectively permeable filtration membrane. In growing, the process of
reverse osmosis is typically performed through the use of a specialized
filtration system. This process is used to clean water so it’s better suited for
effective irrigation. In fact, reverse osmosis can remove
all the dissolved solids from water, leaving pure H 2 0, which allows a
grower to more accurately control nutrient dosage and uptake.
