Dwc resivor change

How often should I change my warter in a dwc setup

I change every week to keep things clean and ferts stable I use 5 gallon buckets. But I have seen others with big reservoirs go 2-3 weeks.

once a week is a good idear, there boss man. The current culture under current has so many airstones, i have heard that peeps will go for over a week and a half without changing nutes. Just what someone told me... When I used the GH waterfarm i changed it a minimum of once a week.

Read your nute solution.. It will probably tell you weekly because of course they want you to use more nutes.. but I get away with every 2 weeks no problem.

few answer been giving, all good.
