Safety for indoor greenhouse?

No, just humidity won't cause sparking. Don't spray water on the plants when the lights are on. High humidity will cause fixtures to rust faster than otherwise. There is a concern if water sprays on high-temperature bulbs. CFL and standard fluorescent lights don't get hot enough for this to be a concern; HO T5 and HPS lights do get hot enough for this to be a concern.

Excellent, thank you!
