I am soooo excited to be involved in the cultivation process. Just accomplished a lifelong dream and began the process of setting up a grow tent. I purchased the 5x9x7 Gorrilla tent and The 12 bucket Grow Flo hydro system. I went with the Stealth Box 3 carbon filter and a Hyper 8' fan plus 4 circulation fans. I Have (2) Gavita 1000 W lights, which brings me to my question. Is the EL-1 controller a necessity with these lights?
