Relationship between Reservoir size and nutrient concentration
Hello growers.
I'm on my first hydroponic (rDWC) journey and still have many questions and problems arising, learning every step of the way.
Lets picture the following scenario to better understand this questioning:
Imagine two systems
One that holds 40 gallons in total with only 4 plants.
One that holds 20 gallons in total with only 4 plants.
Now lets say you run your nutrients with 500ppm on each, same dilution.
Is it possible to assume that the 40 gallon system will potentially burn your plants when the 20 gallon system doesn't ?
Ok, you have the same concentration on both, but on the 40 gallon the plant has more available due to the larger volume, and even though it drinks at the same concentration, it drinks more and more without ever bringing the EC/ppm down due to the higher availability.
Do you see where I am going? Does it make sense?
