I moved the 8 from one tent to the main tent, underneath the Kind 600W LED with a 1000W additional light along side. 2 CO2 bottles, an oscillating fan, dehumidifier, and I like getting my plants off the floor so they are up about 3 inches. I may spread them out to a 3/3/2 layout for more room for each one and I have plenty of extra lights I can put in
