Too much humidity for phals?

[josterha]

Hello fellow phalaenophiliacs,

Should I be worried about a too humid environ for my phals? They are in about 60% RH in pebble trays in my apartment. However, it is still early spring (read winter) in Chicago and too early to open the windows, so I expect by summer for the RH to get much higher. I know they are pretty forgiving, but should this be a concern?

Thanks,

- John
