Layering mosses can definitely work well, especially if aesthetics matter to you. Cushion moss alone doesn't really boost humidity much—it's more decorative than functional—but your idea of combining it with sphagnum is solid. One thing to watch out for, though: cushion moss can sometimes compact over time, limiting airflow and potentially causing mold issues underneath. I'd recommend checking every few weeks and fluffing it up a bit or replacing the top layer occasionally.
Another trick I've used in older homes (especially Victorians with drafty windows) is placing shallow trays of water with decorative stones or pebbles near radiators or heating vents. It subtly increases humidity without looking out of place, and it's pretty low-maintenance.
Anyway, your layered moss approach sounds promising—just keep an eye on moisture buildup underneath. Good luck!

I've tried this too, and it works surprisingly well. Another thing I've found helpful is grouping houseplants together—especially leafy ones like pothos or peace lilies. They naturally release moisture into the air, creating a little microclimate around them. Just don't overdo it...too many plants close together can trap moisture and cause moldy spots on walls or furniture. Learned that the hard way, unfortunately.

I haven't had mold issues myself, but I think it depends a lot on the airflow in your space. Older homes like mine tend to have drafts and natural ventilation, so grouping plants actually helps balance things out without getting too damp. For newer, more airtight homes, though, I can see how that might become a problem. Maybe spacing them slightly apart or rotating their positions occasionally could help avoid moisture buildup? Just thinking out loud here...
Good points here. I've noticed that newer homes with tighter insulation and fewer drafts do seem to struggle more with humidity buildup. In my experience, even spacing plants apart doesn't always solve it completely—sometimes adding a small fan or vent nearby helps a lot. Curious if anyone's tried using humidity monitors to track moisture levels around plant groupings...are they actually helpful or just another gadget collecting dust?

I've actually found humidity monitors pretty useful, especially if you're dealing with tightly insulated spaces. I was skeptical at first—thought they'd just end up forgotten in a drawer—but having real-time data helped me pinpoint exactly when and where humidity spiked. It made tweaking fan positions and vent placements way more effective. They're cheap enough now that even if you only use them occasionally, they're worth having around.
