The media exchange solution test: A better measurement of media effects in hydroponics
In the traditional hydroponic paradigm we want media to be as chemically inert as possible. The ideal media in this view would absorb no nutrients, give off no nutrients and…

Why you should optimize your nutrient solution for your particular setup
In hydroponics, most plant nourishment is delivered through the use of a nutrient solution. This solution is prepared from raw fertilizer inputs by the grower – or a fertilizer company…

Using a biodegradable iron chelate (IDHA) in hydroponics
Chelates are a very important part of hydroponic nutrient solutions as they provide a reliable source of heavy metals. Without chelates, heavy metals can easily go out of solution and…

Using electro-degradation to enhance yields in recirculating hydroponics
The efficient use of nutrient solutions is a very important topic in hydroponics. Although some commercial growers use run-to-waste systems where solutions are not recirculated, the economics of fertilizer use…
