there would bee no benfites sticking a aircube thig into the mud,like stinky said you can use perlite and vermlite to keep oxygen in the soil going to the roots,a thing you could do tho place a aircube in your water the night before feeding the plants or shake the water in a bottle,this will make oxygen present in the water,enought for the roots any way,the main thing you need is a good soil mix.
