Okay, so sorry if this is COMPLETELY retarded, but its just an idea I got for a cheap aeroponics system.

The tank is under pressure, so the water comes out through the mister hoses, which are obtained from those personal misters. If you wanted, you could pressurize the tank with a foot pump or something.
So is this plausible or just completely retarded?
edit-I forgot to mention, you would be sterelizing the tank before, and instead of pressurizing it with just air, you could get all the air out of it, then fill it up with only CO2, Oxygen, and whatever else. I dont know if this would actually have many benifits or not though.
