I was just at the Earthbox research center this afternoon and spoke to Mr. Wislet as well as there other people. They said its very possible to get as many as 10 crops from the same original box of mix simply by removing the old plant roots, scooping out the used fertilizer strip and topping off the box with new mix, than replanting the box. They also spoke of a newer way of laying the fertilizer strip depending on what your planting (running the strip vertical instead of horizontally when planning just two plants) They say this has proven to provide a slightly better growth for the two plants. Mr. Winslet also commented that too much has been made of trying to find the perfect fertilizer, that just about any good fertilizer will work, he stressed the biggest mistake he sees people make is laying the strip and planting the plants so that the two are too close together, he said the fertilizer strip should be as far away from the plants as possible. Had a great visit and picked up everything I needed to get going again. He also has great deals on plants ready to be planed, nice and small roots so a very small "X" need only be cut in the cover instead of trying to get a bigger root ball through the cover.
