Potassium (K) – It’s role in plant growth
Potassium is the most abundant monovalent cation in plant tissue. It is highly mobile which explains why deficiency symptoms can occur so rapidly. The concentration...
Phosphorus (P) – It’s role in plant growth
Phosphorus (P) was first discovered by Hennig Brandt in Germany in 1669. It is ironic that the discovery was made when he was busy with...
Nitrogen – It’s role in plant growth
Nitrogen is consumed in large amounts by the plant. Nitrogen is used in components such as amino acids all proteins enzymes co enzymes nucleic acids...
How to adjust the pH in hydroponic nutrient solutions
Adjusting ph of the water supply is crucial for maximum nutrient availability. It is seldom that the water supply, even from a well, is perfectly...
Differential nutrient removal from hydroponic nutrient solutions
Nutrient removal is quite often neglected in closed hydroponic systems since it is difficult to measure and control. The reason is that not all nutrients are...
Refilling nutrient solutions and refilling frequency
Refilling nutrient solutions are only required when a closed (NFT) system is used. With open hydroponic systems the nutrient solution is not re-used so no refill solution is...
