PH is the measurement of acidity or alkalinity. on a scale of 1 to 14 neutrality is
expressed as 7. higher numbers are alkaline, lower numbers are acidic. the ideal
PH for hydroponics is in the range of 5.8-6.3 PH.
for active hydroponic systems such as nft, flood & drain & Rockwell slab culture
you are able to control and manage the PH & strength (conductivity factor of
CF) of the nutrient solution.this will enable you obtain faster growth rates &
higher yields from your system. once you know the PH of your solution you will
either raise it up or down.
