Do the wrinkles in tents go away?

Purely aesthetic I know. But do the wrinkles from the packing of the tent eventually disappear? Maybe from humidity?

with negative pressure inside the tent it mostly disappears after a while

Most likely not, just means you bought a cheaper made tent most likely made of a thinner material then say the overpriced Guerilla grow tents

My vivosun tent is mostly wrinkle free almost 2 months in. Ymmv.

I have 2 Vivosun tents. The wrinkles disappeared in both of them after just a little time. I don't know exactly how long because it's something that doesn't matter and has absolutely no effect on the function of the tent and I didn't really pay any attention.

If it really bothers you a hand held steamer would probably get rid of them. Don't take my word on that as I've never done it.

Brb gotta iron my tent real quick.

Still see folds on my 7 year old Growlab but they have no real effect. See some vague packing wrinkles on my year old Plant House from Growers House. Again nothing of consequence.
