They are in a glazed ceramic water tray about one inch deep and get watered where the water is level with the top of the media about every 2-3 days.
Water level with the top of the medium? As in almost flooded?
Mine are in 2-4” pots, mostly squat, under T5s. I started with 6500K the first year, but after Ron West said he noticed that high color temps tend to cause smaller leaves, I switched to 2 each of 6500 and 3000K. I have t seen a huge difference though, and suspect it might involve other factors as well. The lights are about 15”
above the plants. My temps range from 60 to 75 in the winter, higher in the summer. Humidity 70-80%. I water by adding about 1/2-3/4” of water to the flats, letting it all be absorbed/evaporated over the next few days, but with the exception of gypsicola and a few others, I don’t let them go bone dry. Seattle water is near neutral btw.
