The flow rate of an NFT (Nutrient Film Technique) hydroponic system depends on various factors, including the size of the system, the number of plants, and the specific requirements of the plants being grown. However, I can provide you with a general guideline for the flow rate in an NFT system.
In an NFT system, a thin film of nutrient solution continuously flows over the roots of the plants, providing them with water and nutrients. The flow rate is typically measured in liters per hour (L/h) or gallons per hour (GPH).
A common recommendation for the flow rate in an NFT system is around 1-2 liters per minute per square meter of growing channel. This means that for every square meter of NFT channel, the system should provide a flow rate of 60-120 liters per hour (or approximately 15-30 gallons per hour). This guideline ensures that there is a sufficient supply of water and nutrients to the plants’ roots while also allowing for efficient drainage and oxygenation.
Keep in mind that this is a general guideline, and the flow rate can be adjusted based on the specific needs of your plants, the environmental conditions, and the stage of growth. It’s always a good idea to consult specific resources or seek advice from experienced hydroponic growers to determine the optimal flow rate for your particular setup.
