All that tape and I'd still probably mix up bedrooms somehow.

Wait, your maidenhair stopped dropping leaves in just 3 weeks? That seems crazy fast for a plant to adjust to a whole new medium, in my experience ferns throw a fit for at least a month when you mess with their roots. Maybe the Denver air is just dry enough that the coir's extra moisture retention made that big of a difference right away. Your mileage may vary, but I'd be curious what your ratio is because straight coir stayed way too wet for my setup.

Yeah man, the algorithm has you locked in now. The move is to stop clicking the ads and start using private browsing or a different app to research, because every click just feeds the beast. I did this same thing with running shoes last year, clicked like 6 pairs, and my feed was nothing but sneakers for a month. What actually worked was clearing my browser cookies and turning off ad tracking in my phone settings (it's buried in privacy settings somewhere). Also try searching for the thing on a site like reddit instead of google, since those threads don't track you the same way. Give it a week and the mattress ads will dry up, at least until you click one again.
