co2 with dry ice ?

has anyone done this and how well does it work and how safe is it ?

not worth the trouble my man. Just keep good ventilation going and save the dry ice for making keif.

lol ok then, dry ice can be used for many things

I agree it would be a waste of money to use dry ice as a source of Co2 - You would need a constant supply of it 0 and a water heater to have it constantly sublimate and tog ive off beneficial levels of co2.

compressed Co2 is cheaper than frozen co2

thank u ty ty

I started using CO2 when I worked at the university. I had unlimited access to all the dry ice
I wanted to take so price was no obstacle. Note -- dry ice is frozen carbon dioxide gas. As the dry ice warms up the CO2 changes from a solid to a gas
which is a form the plant can use. Carbon dioxide is heavier than air so I hang a large ceramic bowl under the fan.

Good luck, BigSteve.
