WW - well thanks to everyone else, I caught onto what the heck you were talking about.
since what you said is pretty vague! IMO if you never heard of something crazy like that.
do you put your whole garden in 1 sq. ft. ?
did you mean each plant gets 1 sq. ft. ?
sq. ft. is vague cuz it can also mean anywhere from 1 -you name it!
it would of helped if you just put 1 sq. ft. gardening for each plant.
depending on the plant I would not do 1 sq. ft. growing, unless it was beans, carrots, onions,etc... but chiles, tomatoes,etc... never!
