I'm considering some active mechanism that retains heat because of the activity of sky plankton, so that infra-red radiation is reflected during the day and retained at night. Moist greenhouse states would normally be short-lived phases, so it is already necessary to imagine some sort of active mechanism that prolongs the state on a Tohul-like world.
What we want is a mechanism that warms the planet to a certain temperature while preventing a runaway greenhouse from occuring; perhaps if the planet heats up too much the skyplankton might actively cool the surface (by causing rain at might?) thus reducing the water content of the air. Certainly the most undesirable property of a runaway greenhouse is hydrogen loss at the top of the atmosphere, so the top of the atmosphere needs to be kept dry and cool if possible.
