NUTRITIVE SOLUTIONS
The nutritive solutions constitute one of the most important factors in
determining the plant’s growth and yield. Hence, putting the right
solution at the plant’s disposal is indispensable to get the best result.
Conductivity (EC) of nutritive solutions must be checked regularly to ensure
that it agrees with plant’s requirements. The plants also have seasonal
preferences, typically requiring lower concentrations in the summer.
