drying with dry ice

cool, makes sence and sounds eassy enough.how can i find out how much co2 is flying aroundin the air, would the amount matter??

I'm not sure hat meter measures it but you wanna keep the cab at 1400ppm. That is the optimal amount. But don't go over that.

if you put dry ice in water you will produce carbonic acid (soda water) basically h20 full of co2 it must be kept under pressure like a beer or soda or the co2 will leave the solution into the atmosphere. but if pressurized and kept you have c02 on hand for future use even after the dry ice is gone. as far as foliar feeding im not sure of the effects but it would deliver co2 in liquid form. i also have access to free dry ice i want to get a meter though because i have dissolved whole blocks and my lady bugs seem to pass out probably way over 1500ppm of co2 at these times i even feel kinda dizzy sometimes i have heard too much co2 impedes plant growth im not sure on this. im also at 3000 feet im not sure if this benefits or not as far as atmosphereic gas levels of co2 go.

My understanding of how the process was supposed to work as fairly straight forward, The theory in my understanding was that as the dry ice moved from solid to gas it created a flow of gas over the buds that had NO humidity as the C02 was dry.

I wrote it off as one of those Canna-Myths you hear so often. How can anything evaporate and dry out if it's frozen solid? If it is possible it's beyond me. I do not reccomend it.

You think that sublimation is a canna-myth?

From Wikipedia:

Sublimation of an element or compound is a transition from the solid to gas phase with no intermediate liquid stage.

Carbon dioxide is a common example of a chemical compound that sublimes at atmospheric pressure—a block of solid CO2 (dry ice) at room temperature and at atmospheric pressure will turn into gas without becoming a liquid.
