In my travels I see RVers with tomato plants, house plants and a variety of other fruits and vegetables. They are usually stationary for a while, like campground hosts or work-campers, and they manage to keep a garden. Here is a portable solution for a care-free high-tech growing system that controls soil conditions and doubles the yield of your crop with less fertilizer, less water and little effort. There is no digging, weeding or guesswork. It set’s up in minutes and can go anywhere. Here is a link with more information Earth Box . It costs around $65.00 or you can make one yourself for around $10.00 Do It Yourself Either way you will get more bang for your buck with this type of gardening system.
