Hello! I have been reading up on how to do plant tissue culture and today is the day I'm finally going to do it and I just realized that there is something that I am unclear about and I can't find the answer! Once I have sterilized the medium, cooled it and put my plant cuttings into the jars of media, am I supposed to put the covers on completely tight or leave them loose? I've read that you wrap the lidded jars in plastic wrap after covering them, so I'm wondering if you have to do that because the covers are left loose. Could you tell me? Tight, or loose? Thanks a lot!!
