Ever since monitoring the #CO2 levels in my office, I noticed that I need more ventilation.

But it is cold outside... while I have been using a couple #DIY heat recovery units, they are a bit loud and consume a bit of (mostly #solar) electricity, and are still a bit lossy...

So I finally decided to search for how many #plants I would need to help keep the CO2 levels down..

Well, that sounds like more than I can realistically manage, but still nice to have plants!
