It's hard enough to successfully print something that holds water properly. If it's at all possible, the best way to handle it is coating the print with something to seal it afterwards. If it's not, making something airtight would require having quite a few walls and especially surface layers to make sure all small gaps eventually get blocked off.
I have had 100% success sealing PLA prints used as plant pots (I know OP is asking about PETG, should still work) with a can of rustoleum spray lacquer, much easier than trying to dial in settings.
I have some clear rustoleum lacquer in my garage, I'll have to give that a try in addition to some of these other tips
