Lmao by all means listen to this guy and jar it when it's too late if the stems are snapping
I don't usually give advice anymore because I spend the time and people don't listen anyway and others give misinformation then they learn the hard way, plus this may be my career one day and I don't really need to teach possible competition not to mention I've probably typed this information out for people to find already five times but I digress...
That ^ is all FACT the following is factual opinion lol, yes it can leave a slight flat side at the beginning but when the buds go into the jar they will compress down a bit anyway. That's part of the key to nice tight buds having a tight full jar in cure and you don't really see much in the way of flat spots on the final product for these reasons. Not to mention I'm not talking about using a piece of plastic or anything they make light, soft material racks with holes in each level to minimize surface contact which in turn causes very little pressing. I've never been a fan of hang drying or drying before trimming and I have tried both. the biggest reason for this is when you're trying to uniformly dry a mass of, anything really, you're going to have damp spots or spots on your cola that will take more time than others to dry. Of course this principle gets worse the larger your colas get. When you're drying uniformly sized buds that get even air contact on the entire surface (what would normally be hidden inside the cola) you get a more even dry. You also get a faster dry time due to the fact that the huge stalk inside, which holds moisture the longest, is no longer leeching that moisture into your bud. By removing the main stalk and all material you don't care about before the dry, you're removing moisture from the area plus more surface area speeds the drying in itself. You're also discarding parts of the plant that can contribute to an unpleasant smell which may linger for some time after if not discarded before drying. I am THAT GUY to all my friends, the connoisseur, the one that would worry about flat buds or the possibility of losing trichs on a dry rack etc. And after a good level of experience (see avatar) I can say confidently that trimming before drying and disassembling the plant down to buds immediately then using a dry rack is the way that has served me best in ALL aspects.
