IMO (I know, you didn't ask for my opinion, but I'm gonna throw it in
), movers generally do not make the most out of your growing area. They are sometimes more efficient with the area you can cover in some situations,but i would recommend against them in the majority of cases. You have, effectively 5' to work with (not sure of your width, but lets say it is 4'). If you want a little more rectangular area coverage than a single 1000 watter (4x4), you have the option of 2 400 watters to cover your 5x4 area, or 2 600 watters to cover the same. Either way will provide ample coverage depending on how much electricity you can buy, and how much bud u want. I ran a mover over a 4x8 area (1 1000 watter) for a while and they just don't work that good. My 2 cents
