Good points on cellulose insulation—I recommended it to a client once who was super eco-conscious. Worked great, but we learned the hard way that proper moisture barriers are key...otherwise, you're asking for mold trouble down the line. Just something to keep in mind.
Had a similar experience with cellulose insulation myself—great eco-friendly option, but moisture control is definitely critical. On one build, we thought we'd nailed it, but overlooked sealing around some recessed lighting. Ended up with condensation issues and had to redo sections of the ceiling...lesson learned the hard way. Now I always stress airtight detailing upfront—saves headaches and money down the road.

Been there myself—it's surprising how easily moisture sneaks in through tiny gaps. Airtight detailing is definitely key, but I've also found that pairing cellulose insulation with a smart vapor barrier can make a huge difference. Curious if anyone's tried combining cellulose with spray foam around tricky spots like recessed lighting? Seems like it could help seal things up tighter without sacrificing the eco-friendly benefits.
Totally agree on the cellulose and smart vapor barrier combo—it’s been a lifesaver on a couple of my recent projects. Haven’t personally tried spray foam around recessed lighting, but I’ve seen colleagues do it successfully. Just gotta be cautious about heat buildup around the fixtures...LEDs help with that, though. Also, worth mentioning: proper attic ventilation can drastically cut down condensation issues, even if your insulation setup is spot-on. Learned that one through trial and error myself.
