Dealing with tight passives

I've been playing a lot in the middle of America's night, when 100nl is dominated by shortstackers and 10/8/2-ish nits with very few aggressive or loose players. It's a little embarrasing, but I've been breaking even at these hours over a pretty big sample, even though I do quite well playing during the day. Obv I'm going to try to play more when the time is good for me, but other than that,
what are your strategies for crushing games full of tight/passives?

My initial thoughts are that you're going to win most of your money preflop and on the flop, and that you should have a very good reason to call when they bet or raise.

Thoughts on betsizing? Adjusting your raising/calling ranges preflop? Barreling frequencies? 3betting strategy? Anything else?
