Has anyone tried using dry ice as a CO2 source for a small setup. I can see potential problems with putting the dry ice directly in the hydroponics water as it may shock the plant with the temperature change. I was thinking more of just having it dissapate in the confined area of a micro grow room ( closet ) each night during flowering. I think it is fairly cheap and could be stored in freezer under the right conditions. Your thoughts?
