co2
I stopped using co2 a few days ago and noticed my plants do not drink as much. The res used to loose a few gallons after a feed, now I do not notice much solution missing. The yeast/sugar method seemed to work. I did have bottles of it all over the place and my tent is small. Next grow I will get a co2 tester to see if it really helped. I really want bottled co2 but can not afford it at the moment.
