Phalaenopsis honghenensis Care
This is a cool-growing phal; to do well with cool-growers like this you need to provide cool evening temps and a differential between the day and night temps of at least 8C. Day temps should not exceed 28C, and beware of bright and/or direct sun. The leaves are a dark green and I suspect will easily scorch if moved from shady to bright positions without proper acclimation.
I grow my phal honghenensis at a South window with with a sheer cloth knocking back about 60% of the sun’s intensity. It grows quite bright, but my windows are well insulated so the leaf temperature is cool. In the summer I run my air conditioner continuously to keep the house temp under 25C. In the winter the temps go down to around 16C in the nights. On especially cool winter nights (-25C OUTSIDE), our indoor temperatures near the window may go down to 12-14C.
I water with pH adjusted water (5.8pH) and flush the pots every week with regular 7.5pH water. Though I received this plant with only 2 leaves, it has grown vigorously and done well.
