Yes, I thought this was ridiculous too, until I really thought about it, then did some research. You may laugh, but if you just stand and exhale on the top of your canopy for a few minutes a day (only while the light is on, obviously) you could theoretically give them enough co2 boost to be noticeable in plant development.
I theorized this is why my plants seemed to "miss" me. I'd go away for a few days and not see much growth when I got back - then after 24 hours of being home they would explode! Of course there are other explanations for this, but I feel it could certainly be a contributing factor. There is legitimate research that singing to plants increases growth rates as well, possibly explained by the CO2 link.
Obviously if you have over thirty plants you would pass out trying this method. HOWEVER for micro - to - small closet grows, I believe this could be a legitimate and safe method of boosting co2.
After all, human breath is 4% CO2 exhaled - that's 40,000 ppm!! even an increase from 300 to 500 ppm in the grow area can drastically effect your plants.
