Many hydroponic growers have found it necessary to filter source water and perhaps use reverse osmosis to remove some solutes so that it is pure. Ec of source water should ideally be less than 0.25 ds/m for closed systems. During weeks 0 and 1, rates may be half this, and the upper limit of 2l/min appears to be the maximum you should run during the flowering phase.

You don't need to aerate your troughs if your flow is moving at a reasonable rate (3gph or more, not too fast, not too slow), shallower is better so long as your pump doesn't fail, and gives you more surface area to volume, which means your gas exchange will be better and. The correct flow rate of closed hydroponic systems is critical for optimal growth of plants. The length of the tube in your nft system isn’t really important, and wont affect the flow rate or gph you need to pump. Of lettuce in hydroponics hence it is stated that flow rate of 20 l/hour is good flow rate rather than 10 l/hour and 30 l/hour.
