If you in the US, you should be fine with 4000. My buddies last grow was 5200 and in the winter you can even go higher because 1) it looks like spaceheaters 2) you don't need AC / chillers.
Just make sure the house has solid doors, locked windows, ideally a car in the driveway or garage, cameras, ect. Also, if your not going to be there, remember to be super careful with all your wiring / ballast placement -- smoke detectors and fire extinguishers don't do shit if your never there.
