CO2 System Setup - HELP

So the image below is my grow room. I am going to be adding CO2 using a rain system. the directions say to attach the big circle of tubing dispensing the CO2 to the ceiling directly above the canopy so that the CO2 can fall/rain onto the plants. my question is should I really put it on the ceiling which is 10ft up and above a large hurricane oscillating fan on the wall. I am worried if I put the tubing above the fan than the fan will just blow it all over the entire room and it will not go onto the plants the way it should, especially those directly under the fan. The room ventilation will be off during the day when the CO2 is being added but planned on leaving the fans on. It will be helpful to note that the room is 12 ft long. only the back 6x6 is the grow space. the other half of the room is for storage, and a clone/mother cabinet.

Should I hang tubing below fan (location 2) so that the plants directly under the fan will still get CO2 or should I have all ventilation including wall fans turned off during the day and just attach tubing to ceiling (Location 1)? Or does it even matter? lol

Any advice would be great! Thanks!

is your grow room sealed or recirculating? i don't know CO2 equipment BUT i do know if your grow room is sealed, it will not matter where you put the CO2 rain ring cuz the space will fill...fan might mess with your monitor/controller getting an accurate reading though so i wouldnt have high fan speeds...or maybe that don't matter, idk. If there is someone that knows, i'm not sure why they didn't help you.

Thanks for the reply. Yes. I shut off exhaust fans during lights on and the only leaks are under the entry door. I have since installed the system in location 2 but realized it does not matter. The rooms fills very fast. Only takes a minute or less of the co2 running at a flow rate of 6 to get to 1500 ppm. The monitor doesn't seem to be effected by the fan. I've turned it off and on during co2 cycle and room fills up same either way. I think the fans actually helps keep the co2 up off the floor longer. When fans on it seems to take longer for the ppm to drop below 1400 which triggers the cycle again.
