Honestly, I’ll take a bit of straw funk over VOC headaches any day, but yeah, it’s not always a quick fix. I’ve found that if you stack bales with a little more air gap, it helps some. Just don’t skip the vapor barrier—learned that one the hard way...

Yeah, skipping the vapor barrier is just asking for trouble—been there myself. I’d add that if you’re worried about straw bale funk, try staggering the bales so the seams don’t line up. That way, you get better airflow and fewer cold spots. Also, make sure your plaster mix is breathable. I once used a too-dense lime plaster and it trapped moisture... not fun to fix later. VOCs are nasty, but mold’s no picnic either.
Skipping vapor barriers always seems like a shortcut until you’re ripping out soggy insulation six months later... Been there, too. Curious though—do you think breathable is always the answer? I’ve seen some “breathable” plasters still trap enough moisture to cause issues, especially when folks get creative with their mixes. Also, how are you handling VOCs in finishes? I find half the “eco” paints still reek for weeks. Maybe it’s just me being picky, but the off-gassing never seems as low as advertised.

I hear you on the “breathable” plasters—sometimes it feels like we’re just trading one problem for another. I’ve seen a couple of projects where folks got a little too creative with their lime mixes, and suddenly you’ve got condensation hiding out behind the walls. Not fun to discover during a walkthrough.
As for VOCs, I’m with you. Some of those so-called eco paints still have that chemical funk, even after the “safe to re-enter” window. I’ve started doing the sniff test before committing to a brand, which probably looks weird at the hardware store, but hey... better than living with that smell for weeks. Honestly, I think some of these low-VOC claims are more marketing than science.
I don’t think there’s a one-size-fits-all answer here. Sometimes you need a vapor barrier, sometimes you don’t. And with finishes, it’s trial and error—plus a lot of reading the fine print (and maybe annoying a few paint reps).

That “sniff test” at the hardware store is honestly underrated—sometimes it’s the only way to tell if a paint’s actually tolerable. I’ve had a few “eco” brands that still left my house smelling like a nail salon for days. It’s wild how much the marketing can stretch the truth. I’ve started looking for third-party certifications (like Greenguard or ECARF) instead of just trusting the “low-VOC” label, but even then, it’s not foolproof.
On the plaster front, I totally get what you mean about condensation. There’s this weird balance between breathability and moisture control, and it feels like every house is its own science experiment. I once helped with a retrofit where we skipped a vapor barrier because the old brick needed to “breathe,” but then we ended up with damp patches behind the lime plaster. Turns out, the local climate made all the difference—what works in one region can be a disaster in another.
I’m curious if anyone’s found a finish that actually lives up to both the green claims and real-world performance. I’ve had decent luck with mineral paints, but they’re not always easy to find, and sometimes the color selection is... let’s say, limited. Also, has anyone tried those natural oil finishes for wood? I keep hearing mixed things about durability and smell.
It does feel like trial and error most of the time. Reading the fine print is key, but even then, you end up bugging paint reps or just taking a leap of faith. At least we’re all getting pretty good at deciphering ingredient lists by now...
