In the past few days I have had some seedlings emerge. "Lophophora williamsii" I have the pot on heat and covered with plastic wrap. How long should I keep them covered and on heat. I live in a cool environment rarely gets above 80°f.

That plant does not need any heat to germinate or grow. I speak from experience in our extremely mild climate (most of the year temps are in the 60s or 70s during the daytime). I just left mine indoors in front of a window, covered by clear plastic until they were maybe the size of a cooked pea. Room temperature (say 70°F) is fine.

Do not make the mistake of lifting the lid too early. These plants enjoy a lot of humidity when they are babies, and then once they are a reasonable size you can gradually wean them off the moisture. While they are under plastic, you also have the advantage of a relatively clean environment where lots of microorganisms don't drift into the picture.
