I'm growing orchid seedlings on a light setup plus running a humidifier and no, with home heating and air conditioning, creating humidity is actually the issue. You shouldn't have any issues.

I have to agree. Even while running a humidifier it's still a struggle to keep the humidity up, especially in the winter. I have a ceiling fan running also and it causes everything to dry out quickly and works great to prevent mold, mildew, damping off.

I agree with the above folks. If you're really worried about it, keep the bedroom door open so the humidity dissipates throughout the rest of the house. But even with a whole house humidifier, AND a large room unit, I can't get the humidity above 70 percent indoors with all the lights running (the lights create heat which dries out the air).
