pod said:I've never started Coleus but would think I would not overwater until they put on at least the first set of real leaves so the plant could dispose of the water. I have read that only 5% of the moisture is used by the plant and 95% is transpired through the leaves. Without leaves the plant will drown/rot. Most common in seedlings. Too moist also sets up conditions for disease. I would continue to mist till leaves are formed. Then I'd start bottom watering. Good luck.

I always bottom water seedlings. Established seedlings can get water on the top soil, but I would not mist them. There is little advantage unless you are trying foliar feeding, and seedlings generally don't need that.
