Hi,
I have a south facing window that doesn't get much sun because we live up against a mountain on the north side and it's fall here in Vermont.![]()
I got three flourescent lights with plant bulbs in anticipation of winter, but I'm not sure it will be enough for my renanthara, cattleya and oncidiums. They're all growing fine, but the leaves are dark green. (the oncidium and cattleya are sending up spikes, however). Are there any suggestions for increasing the brightness? More lights? a specific type of bulb?
Also, how much humidity is too much? I use a basic humidifer on low all the time, but my husband brought his humidity tester from work (he's a temp. controls guy) and the humidity in the room was 85%. That seems like a lot to me.
Here are some pictures:
And my phals, blooming like crazy for 3 months now:
