Phalaenopsis with droopy leaves

[Ross]

I'd suggest the lights are way too weak. I have mine in a south window exposed to direct sunlight and supplemental CF bulbs that consume 105watts (equiv to 500 watts tungsten and output 6900 foot-candles.) Leaves should be light green and perhaps tinged with purple on the margins (but not always). The leaves of mine stand up straight, not wimpy. They are very firm to the touch. You don't need to let roots turn real white, just whiteish. You may not be watering enough.
