For perfect plant growth: determine the optimum potassium level to control fertilization in freshwater sTest rapide: fill a test tube with test water, add the reagents, pour the cloudy test water into the special test tube until the cross on the bottom is no longer visible, then read off the reading. This figure corresponds to K in mg/l. Too little potassium stunts plant growth, even in the presence of tous autres factors such as CO2, iron and light. To increase potassium content, use JBL Ferropol or JBL ProScape K Macroelements. Detailed information on water analysis and problem-solving can be found at JBL/Topics.
