Dry Ice

can you use Dry Ice as a form of Co2 cuz thats what dry ice is compact Co2

This is only conjecture, so fair warning. But given that dry is just impacted CO2, you should be able to use it provided the fog that sublimes off of the ice doesn't affect the humidity or the temperature in your grow area. If you can keep those factors under control i'd call it a winner.

till you have to pay for it, it goes hella fast tanks or burners are more reliable

I managed to wangle a Co2 bottle from work (bar) , the ones at about 4ft, Im getting a regulator of my friend so I can leave it slowly letting C02 into the grow area.

its really cheap where i live about 99 cents per 3 or 4 pounds and it dont fuck wit my temp and humdity thanx for the replys
