Samaki Posted June 30 Share Posted June 30 I have a 20gal long and all of my plants require 20-35 PAR. I also have the Easy Plant Light. What setting should I have my light on? Link to comment Share on other sites More sharing options...
Administrators Cory Posted June 30 Administrators Share Posted June 30 @Samaki The PAR at 100% is 177 on a 20 long. To get 35 par, you'd run it at 20%. Each 10% increases the par by 17.7%. so 10% is 17.7 PAR , 20% is 35.4 PAR. Link to comment Share on other sites More sharing options...
