You follow the path of power supply, not draw.

wall outlet->Hydrofarm->VE200->Flexwatt(rack)

Therefore your Hydrofarm is your main, just like in a circuit panel your MAIN breaker is the closest to the incoming power source.
Well let me clarify and this is last post for me because we are now off the subject. I consider the VE200 the main as in it is controlling the temp on the flexwatt. The Hydrofarm is the back up.

Have a great night.
