our electricity is more expensive, so i cant be using 6 or 8 sf 1000 , i wont get much out like this i think, can i ask how much time do you give from seedling to flowering and how much do you average yield
you prolly no longer need to use the AC if switching from HID to LED.
But if you still need:want to keep tha AC and work with 4x6 you can go for:1 SE7000 (4x4) 1 SF2000 (2x3) 1 SF 1000 (2x1)
People on here have given you great suggestions so it is time for you to do your homework and decide for yourself. Peace!Good luck growing, now it is time to move on.
