Dry Ice = Co2 = YES? or NO?

I have access to dry ice in small amounts. So i ask-

The "smoke" that you see coming of dry ice is Co2 gas right?

If so, could i direct that smoke to my grow room to up the Co2 levels?

Has anyone tried it, i searched RIU but found nothing :(
 
Heard about someone using dry ice near an intake fan to cool the air and raise CO2 in a magazine I think. The "smoke" is most certainly CO2 gas and will increase your ppm levels of CO2. Can't say how well it will work without knowing your grow space and dry ice weight, but it should be interesting. Please report the results here if you plan to test it out.
 
Yes it would work. How ever go get a 20 lb container of co2 and use a dilated realeaser. I have mine set for every 15 mins an hour

How big is your space? What ventilation do you run? How much can you get a hold of at once? Do you have a CO2 meter?

Space is 1.7m wide, 750mm deep, 1.6m high and ventilation is poor, circulation inside is good (high temps too), and no i dont have/cant afford a Co2 meter.

Dry ice seems like it would be perfect in a small space like this, with a light using a closed cold air ventilation setup. Without a meter though its gonna be hard to know how effective it is and how much CO2 is actually released. I'll have to step aside and let someone who has tried it give you input.
