Mechanical filtration is not an effective tool to prevent water borne diseases in NFT hydroponic nutrient solutions.  It has been found that the total organic carbon content can reach 20 mg.L-1 for 2-3 months without affecting plant growth. There are many other compounds that attribute to the total carbon mass such as chelates and the [...]

Installing a sump on small closed hydroponic systems is also easy. The same basic concrete sump can be build but a simple ‘T-piece’ as described in the figure below can also be as effective. However, floating particles in the water will not be removed with this method. The water in the ‘inline sump’ must not [...]
