I left the lights on for too long a few times and now a few of the orchids seem to have gotten a bit burned.
I've placed the burned ones further away from the light, I'm being more diligent about limited light duration to 12-13 hours, and I'm supposed to finally receive a light timer from Amazon tomorrow, but I also think a fan might be useful. Does anyone have a recommendation for a fan that would create a soft breeze? I'm currently using a Vornado fan pointed away from the orchids at the wall perpendicular to the plants and hoping that the indirect air movement will do some good. When I do this it lowers the temp by 2-3 degrees on the hygrometer so it must be doing something, but I don't have much experience with this. I'm also running a ultrasonic humidifier so it's a balance between giving them air movement and giving them humidity.
