I just found my wife giving some of our plants a drink of tonic water, she swears blind that it is good for them, I have no idea if it is or not. The only thought that I had was that they like to take in CO2 from the air and convert it to O, so can they do the same via their roots?
Any thoughts welcome.
PS, it was 2 years out of date, so she is not completely do-lally. (she asked me to add that bit as she did not wish to throw it down the sink!)
