if i were to take a cooler a 4 1/2 inch or 120 mm in line fan some 4 inch duct and some dry ice and but that all together would this make for a sufficient source of co2 to the plants.

i plan to attach the fan to my cabinet from the inside. hook the duct up to the fan by way of flange and run it to the hole in the igloo cooler. there will be about 3 feet of duct. and i am working with a 5 sq ft space in a cabinet.

i do not want to have the dry ice inside the cabinet thats why i chose this way of doing it

will this work or will it cause a temp problem?

has anyone tried dry ice for co2?
