If you don't control humidity, you're doomed. The first thing I thought about, from your first post, was rust.
If it's spreading in the room, there's a good chance it's going to spread outside the room unless you have negative pressure. Possibly home with your employees and anything the plants touch. Consider that when you remove your special clothes, your touch them to your hands and whatever you're wearing underneath.
I don't know how long it took the clones to make it to your company. However long, they were packed in something wet. Maybe plugs or cubes? Maybe dirt? Even a couple days will breed bad juju.
You can tell your new owner he screwed up.
