PH & Nutrient Control
- You need to regularly check and maintain your Hydroponic system. Whether you do this manually or automatically is up to you, but the 2 key measurements to observe are the pH level and the strength of the nutrient solution. So just to recap on school science, pH is a scale running from 0-14 which determines acidity. In indoor gardening, the scale is used to measure how acidic or alkaline your growing medium or nutrient...
- solution is. Acceptable pH for most plants is somewhere between 5.5 and 7, with the optimum range somewhere within that. It is essential to your success as a grower to ensure that your plants have the right mix of nutrients available to them and as they can only access the optimum mix of nutrients within this range. In fact, we recommend that you let the pH level drift up towards the top end of that scale for a few days before bringing...
- it back under control as this ensures that the plant receives a greater range of nutrients. Use a pH meter or pH tester to check the pH levels and use pH Up or pH Down to bring any potential problems under control. Conductivity Factor (CF) or Electrical Conductivity (EC), is the measurement of dissolved mineral salts within the nutrient solution that you are supplying to your plants. You will need to adapt the EC level depending...
- on the plant you are feeding; a lettuce for example will need a weaker solution, while a tomato or chilli require something stronger. Use an EC Pen to check this. We also recommend that you consider using a water heater. A water heater does exactly what is says on the tin. It will heat the solution to the required temperature ensuring that you don’t shock the roots of the plant as can often happen when the solution is too cool.
