Barnes Posted October 21, 2021 Share Posted October 21, 2021 With it being a recirculating system what do people do about flushing? My ec is 1.8 so when i change to plain water that will bring it down some but will just keep recirculating. Plants taking water but no feed make ec go higher.. How many res changes would it take to get to just the background ec? Thanks Link to comment Share on other sites More sharing options...
Arthur Mix Posted October 21, 2021 Share Posted October 21, 2021 Used to run the res lower water level and as it flushed topped it up to drop EC again not that it raises lots , just the way I used to do it I’d also dropped of high level feeds beforehand. 5 Link to comment Share on other sites More sharing options...
zaaboot_1 Posted December 18, 2021 Share Posted December 18, 2021 Use the pump in the tank to pull the water out in to a bucket or something, it will not be totally empty - full with water and do it again once or twice then you should be clean z 1 Link to comment Share on other sites More sharing options...

When refilling with water, pour it into the pods to flush the residual nutrient out of your grow medium. 3 Link to comment Share on other sites More sharing options...
