Grounding is super easy and has so many benefits to it. That's cool that you grounded and went out on a hike. My wife and I have been going on walks barefoot and we always feel better after.
I don't think that grounding plants together will have any added benefits to them already being grounded. Think of it like all the plants being grounded out in nature, but with these indoor plants, the root systems aren't connected by the mycelium network. Now if I can incorporate some sort of network like that between my indoor plants, that would be pretty cool.
I’ll have to look into those Faraday Cages. I have been wondering about the effects of Wi-Fi and have even turned it off a few times while we have been asleep.
They usually recommend turning off your wifi when you aren't using it... but it's almost always in use. 5g has some impacts, depending on how close you are to the poles transmitting. It's strange 5g is stronger but requires a more tight-knit network of the transmitters. There's a ton of info out there that isn't crazy conspiracy but 'grounded' in fact. And that makes sense about the lack of connection to the mycelium network and actual earth.
