Susanne I am a windowsill grower and my Cycnoches culture is like this in the spring after the new growth is about 3 inches and you have some good growth on your roots, I began to water the plant but do not water to soon make sure the roots are growing and the new growth is about 3 inches or so.
As the temp warms up in the spring I move my plant outside to my patio where it gets morning sun, be sure to work up to the sun as not to burn the leaves. The plants require constant moisture and regular fertilization at this time of year.
Sometime after flowering, in the late autumn the plants will begin to enter the dormancy phase. As this slowing takes place you want to cut down the watering and let the plant go into its dormancy, where it gets know water at all. This is a very important step.
