A water purification process that forces water through a semi-permeable membrane to remove dissolved solids, producing very low-EC source water ideal for precise nutrient mixing.
Dakota runs a new RO filter system (Ecojet 110) alongside the primary pump. He runs the osmosis for 45 minutes initially to flush food-grade preservatives from the new filter. The filtered water feeds the main irrigation reservoirs.
