Hello everyone, I'm planning to grow 4 plants in a grow tent "Grow Lab GL80" (size is 2'7" x 2'7"x 5'11"). I have 3 questions for you, colleagues: What pot size should I use to grow 4 plants (2 sativas and 2 hybrids) in the aforesaid grow tent? Should I use 400w or 600w HPS bulb to fully cover my plants with light? I'm planning to use air cooled reflector to keep it cool. How much Air Flow Capacity (CFM) should my Inline Fan have to decently operate with a carbon filter and air cooled reflector? Looking forward to hear from you, guys Thank you!
