dont drown your seedlings. so many new growers kill their plants with kindness. if you have them in a humidity dome. keep the dome sealed. you dont need lights til you see the seedlings emerge. a propagation heat mat under your tray can help. WHen you see them pop a T5 fluorescent bulb is good and very failsafe for seedlings. Dont give up! this is a learning lesson. Ive killed many pricey seedlings in the quest to grow weed
