Hi Jerry
The guy that made the video said it was just like growing with hydro but in soil. because of not having to worry about over watering your plants You can use this method in any size growing area, with any amount of plants you want to grow I couldn’t believe the size of those plants when I first watched the video. There is also a video on Youtube it s called " Air Injection Technology For Soil" if you are looking to
get your soil more aerated, this is the shizit use this link
" http://modularhydro.com/ProductReviewsAir_Injection_Technology.html " and you find under " Air Injection Technology for Hydro " the information about " Air Injection Technology for Soil " that might interest you… I didn’t think it would be possible, I thought the soil would clog up the holes of the aerator, but I was proved to be wrong after watching the video
