Safety for indoor greenhouse?

[Zabeta]

Hi everyone,

I recently acquired one of those small indoor greenhouses that basically consist of a frame and shelves and a plastic covering. It's about 6' tall, 5' long, and 3' wide.

The purpose of this was to increase humidity for the orchids; therefore, I have a humidifier that I run intermittently to get the humidity up to 70% or 80% (but not lower than 55%).

However, I also need to supplement the natural lighting in the summer months. In the previous set-up, I had the plants on a table by the window, and lights shining on them throughout the day. For the greenhouse, I've bought some clamp light holders with reflectors, and also some CFL bulbs with the equivalent of 60w.

My question is, with all the cords from these lights, as well as the lights themselves, is there any sort of fire hazard from running the lights along with the humidifier? At this point, I'm trying to build up the humidity in the morning, and then run the lights after the humidifier is turned off. But it depends on me being here to monitor everything and make sure the various functions are running separately.

I haven't found anything online. Since it is a small space, I'm being extremely cautious. What do you think?

Thank you!
