>Anyway. Having a couple of plants is not a bad idea. You get better air quality, and more humidity, which is good for your nasal mucosa.

I don't think that one or even several plant can improve air quality. I've heard about studies about this, they said you need dozens of plants for one person to get some effects. So it is more psychological.

Also surprising, but this plant participated in some NASA study and even removed some benzene from air: https://en.wikipedia.org/wiki/NASA_Clean_Air_Study

I also have two small cactuses (cacti?) that were given as gifts, they are old and became yellow. I guess some fertilizer or such is needed for them too.

If you talk to the plants, it isn't madness. Real madness begins when they start to talk with you.
