So i have a 2ftx2ftx4ft high setup im working on 100cfm intake at bottom 100cfm exhaust on top i plan to run 1-2 autos at a time in soil from start to finish in this tent. which light would be best for my space i dont mind spending more on the hlg135 but if the hlg100 is more than enough i also dont mind saving the money. What do you guys think?
