I use pee from a person I know doesn't smoke, fill a 20oz bottle with it and then fill washed condom with the bottle and freeze the condoms for later use.ever tried that fake pee? ive passed a d/t wit dat
im not saying your wrong but i thought c02 was lighter then air ?i remember somthing bout atomic mass of carbon at 12 and air is 14? im years out collage lol...You only need CO2 if your running temps over 80. Also you have to not run the circulation fans during lights on or else the CO2 will never amount to enough to get any noticeable growth.
Don't waste the time on a little 20oz bottle. If you want to generate CO2, brew 5 gallons of beer or ferment 5 gallons of wine, but you will have to start a new 5 gal bucket every 2 weeks, so that will take up all kinds of space.
Also, during the first 24 hours the yeast needs oxygen, do not cap the bottle and your yeast will make more CO2.
CO2 is heavier than air so if you set it on the floor of your grow box it will never reach the leaves, also your roots take oxygen and CO2 where they expect oxygen might cause problems.
I brew and have noticed a tiny change, but not enough to justify it for marijuana purposes.
Your light should be on a sealed air system before you do anything like this though or you will just cook the plants.

Here you go:im not saying your wrong but i thought c02 was lighter then air ?i remember somthing bout atomic mass of carbon at 12 and air is 14? im years out collage lol...
Most growers let the CO2 fall onto their plants and it works well.Wikipedia said:The carbon dioxide gas that results from the sublimation of the dry ice tends to settle to the bottom of tanks because it is heavier than regular air.
Right, your pH drift sounds to be from being too dry. Just what I'm guessing from over the intrawebz.ya ive heard bout the colors ill be using hps next time though got me 2 400 Watt;s
so ur sayin that since shes gettin so dry its throwing my ph out of whack???
it was the gallon jug with my nutes in it which the ph was 4.7 in my runnoff was ok i believe idk ive never once checked it lol
