The most moneyless way to grow is outdoors near a creek or river... Give us info on what type of cheap grow you mean, indoor/outdoor. Cheap lights would be the 42watt CFL lights which cost like $9 each and you need probably 3 but 4 would be better like Psycho4Bud said, But thats for indoor. Everyone knows that outsoor growing is the cheapest but security can make you alittle crazy...
