Accurately preparing large quantities of concentrated hydroponic nutrients
When preparing concentrated solutions for hydroponics it is important to have a reproducible process that always generates the exact same results. If this is not done, you’ll obtain different nutrient…

Why TDS is NOT equal to Total Dissolved Solids in hydroponics
Electrical conductivity is a very commonly used measurement in hydroponics, yet a very poorly understood one. I have written several posts about conductivity in the past (1,2,3) and today I…
