Interesting advise but I wonder how much O2 a plant will produce and really help? Let's say for example, I have a 1 square meter box that has no O2, and I put a plant that you highlight in your article in the sealed box...how long until the box will be filled with 02?
We've all heard that plants produce O2, as a doctor who recommend plants, can you it to us in real terms of just how effective plants are?
Then I will know about how many plants I want to buy for my apartment and actually have a difference. Thanks for your advise, I have enjoyed all your posts.
