In Hydroculture, a higher dose of nutrients is used. This is the main reason for a higher concentration of nutrients in Hydro A & B. Hydro Rokz (clay pebbles) barely retain nutrients and they flush out easily. The roots do not have a lot of time to take up extra nutrients from their surroundings. So, in order to meet the needs of the plant, watering needs to be done more often and with a higher concentration of nutrients. The higher concentration of nutrients also enables to circulate the nutrient solution, because the solution will remain rich in nutrients for a longer period.
Because certain nutrients in the solution chemically react with each other in high concentrations, the nutrients come in two separate bottles, A and B. The A and B concentrates may only be mixed with each other in combination with water.
1 – 3 ml A and 1 – 3 ml B per litre of water.
