Well atleast I went through the thread for a slight review of topics. Very interesting have to admit.....soooooooo many options and difference in opinion lol
So the control res is not necessary than right ? Just connect both totes with the 1.5 in pvc between each other. And a T connected to the inline pump ?
Anyone have any ideas maybe experience in a 3 site rdwc for a 5×3×10? 4 site seems too much for I have to take in account the main resevoir. And I would have preferred to have it outside grow area but that's a cant do lol
