Do I need to break big fat colas For cure?

You don't have to. It might reduce risk of mold in some situations. It can help make drying times more consistent across your entire yield etc you may not want to do it if you struggle to get a slow dry. Context matters. It's another tool to impact drying times. E.g in an arid area, larger buds are probably better for a suitable drying length. Or, leave it on branches or entire plants etc. Maybe you want somethign to show friends to impress them? but, that's probably a 1-time thing, lol. As far as impacting taste/smell - only if it's put in too soon and isn't dry enough. you may have to remove the big colas as they sweat out the extra moisture by comparison to smaller buds.

I was taught to break down bigger buds for the most part. I do like to keep a couple in my jars because if I break them all down too small then they can clump together into one giant mass. Sure they look sick but..not when they get mold on them. Sometimes buds get so thick its kind of hard to tell if the pant could have some bud rot going on without diving into it a little so it's good to check anyway before jarring things up. And it depends on the bud structure and node spacing how much is going to be optimal to break it down. I dont think it will affect the taste too much as long as they are not too wet going into the jars or dried too quickly.

Just make sure you dry them low n slow, bigger buds will need more time. I like to separate mine for better handling and ease but you could use one big as jar with a rh packet. Just keep an eye on it.

No, size of buds will not cause any issue with curing. Any size, from tiny to enormous will cure just fine.

Hello mate, i noticed that when i cure the big buds without separate they the moisture becomes more trapped and this causes a buds spongier. The terpene profile also takes an extra gear, in my experience too much branch release a grass taste in the buds. Enjoy the harvest!!

Defo not if they are nicely dry you wont have any issues and then you will enjoy breaking them afterwards just before you smoke em

if drying is done right and you have big enough jars for curing, i would leave as it is, always fun to smoke big bud. never had problems personally.
