Like many people, I start seeds indoors so as to be able to plant them out when spring arrives. I put transparent covers over them while they are germinating to avoid the risk of them drying out. Then afterwards I also leave the covers on for as long as possible since I often have to leave them unattended for a few days and I fear that if they are uncovered they can dry out and die in that time. In fact I often leave the covers on until the plants are about 6" high. I am starting to wonder if there is some reason why I should NOT do this. I read an article on some plant recently that emphasized the need to remove the cover as soon as the seeds germinated - and although I could see how a cover might be unnecessary, I can't see how it could be detrimental. Anyone know?
