Dude, the waterfarm is the easiest to maintain system out there. If you use the 3 part nutes, you won't have problems with clogs. If you use the floranova series, you will have clogs though. There is a lot of crap in those nutes which makes it gritty and super frothy stuff. I recommend sticking with the more liquidy style nutes. But I put an airstone in my reservoirs because it definitely makes a difference on your root mass and yield. Hope this helps.

P.S. It is okay to flush every 2 weeks during the first 4 weeks of grow. Afterwards you will need to do that weekly.
SAP420 Reviewed by SAP420 on . GH Waterfarm Question Is it neccessary or beneficial enough to put an airstone in the bottom reservoir seeing as how this particular unit pumps the water up to the dripring using air anyway?Also, is the water/nutrient changing schedule still best every two weeks with this system?
