they are growing just as you see them in the picture. I use the lowii and the Landmark to shade the two mottled-leaf paphs, and the longifolium gives a little shade to the other phrags as well. the window faces south. there's a building across the street that blocks the light during the noontime hours, but during the morning the sun is unobstructed, and there's a few patches of unobstructed afternoon light. I don't use any supplemental lighting.
temps range from 65 winter mins to 85 summer maxes, with about 5-10º day-night variation. humidity is around 50%.
most of the plants you see are growing in primeagra. the smaller ones are conventional culture, the bigger s/h. they all get dilute (75-100 ppm N) MSU fertilizer with each watering, except for periodic flushes with tap water every few weeks).
I should take a new picture in the next couple days--the phrags opened up new blooms.
