you can but if the plant is sensitive to humidity change it could kill the little guy once you moved it to a lesser humidity. I like to start them in high humidity before their "true" leaves set in and the starter leaves open up fully seeking sunlight. I only do this because my clone box is warm and seedlings grow faster in a warm humid environment, so my seedlings break soil in a day and open their starter leaves in 2 days. At this point they are in solo cups and i move them under a 4' 2 bulb T8 floro until they are about 6"
My whole germination cycle from day one of germ is about 2-4 days, 2 days to break shell & 2 days to break soil so i'm pretty happy with it
