*The value of EC and pH should be maintained between 1.5-2.5ds/m and 5.8-6.5,respectively.Sudden change of pH and EC of nutrient solution should be avoided.
*knowledge about nutrient deficiency symptom should be obtained.
*Temperature of nutrient solution should be maintained between 25degree to 35degree Celcius.
*Oxygen supply to the nutrient solution should be enhanced because due to Oxygen deficiency, plant root is damaged and yield is drastically reduced.(Left picture shows plant roots due to circulating system and right picture shows roots due to non circulating system.)
*Sufficient light should be ensured and disease free seedlings should be used.Diseased plants should be uprooted.
*Insect mite attack such as aphid,leaf miner,thrips,and mite attack may be observed.Necessary steps should be taken to prevent them.Daily monitoring should be done.
