WHILE IT IS very
important to know
the strength of the
nutrient solution
applied to your crop,
it is equally (if not
more) important to
monitor the amount
of soluble salts in
your root zone.”
There are hundreds of different fertilizer brands on the
market, and whichever one you decide to use, make sure
it provides balanced levels of macro- and micronutrients
necessary for the crop you are growing. EC and TDS meters are
great tools used to check the strength of your nutrient solution,
however, if you want to know the composition of specific
nutrient salts that are contributing to your solution or media,
you will need to have a chemical lab analysis done. Different
fertilizer salts contribute to the overall EC differently, and
certain nutrient components like urea will not contribute to the
overall EC until its converted into nitrate (NO 3 ).
Plant nutrition is just one important variable to consider when
making adjustments to optimize your controlled environment.
