strength of my hydroponic nutrient solution
 

Hello Ron,
Using a home built drip system setup in my back yard in Southern Florida my reservoir, ( 10 gal. )
will sometimes be over full with rain water or almost empty due to evaporation i.e. heat and humidity
or lack of it. I am using using General Hydroponics 3 part nutrient system. Other than buying a meter
or dip stick that I can not afford, is there any good way to check out the strength of my liquid before
I add water and more nutrient or pour it out and use for 'ground plants when too full? or good rule of
thumb to go by? Thanks Greg B. Fort Lauderdale Fl. -- President and Founder ...

Hi Greg
The only way to keep track of how much nutrient to add is to add a gallon at a time to your tank
after adding the amount that it calls for on the nutrient instructions.
