When the wife gets home from work we go hang out with the plants so she can wind down from the day. I make up stuff to do just to be in there!!! Last week I installed a central wet/dry vacuum so I only need to connect a hose and flip a switch to keep the floor clean and the girls and I can still hear the stereo! I also use the vacuum to remove the runoff from the trays after watering.I'm sure all of your exhaled CO2 would charge up the plants.
