question about co2 injection

[ben350n]

so i have been reading about co2 injectors, and they sound like a real pain. i was wondering, would it work to put some sort of grate or platform on the back of your fan, big enough to hold a ~3 pound block of dry ice, and throw on a block once or twice a week? i would think it would be easier than filling up the room with co2, since the fan is blowing right on your plants, so ergo the co2 is blowing right on your plants.

i have never put it into practice, just a theoretical suggestion/idea.

please give feedback, good or bad, i want it all :jointsmile:

You would think that there would be some measureable positive effect?
Considering the amount of effort put into it you would think that you could get a return that was worthwhile, just be sure to turn off the exhaust. I am sure someone here has tried it.

That's too much CO2. If you are going to run a dry ice CO2 emitter, it should be a heavy plastic cooler with some small holes drilled in it to allow a slow seep of CO2 while keeping to block of ice very cold so it doesn't melt within a day. I don't know what size block of dry ice you are expecting to take over a week to melt! Or, technically, to sublimate. CO2 can not be liquid at standard conditions.
