Abstract: A method and apparatus for controlling light and temperature necessary for the optimum growth of vegetables and plants for backyard gardeners. This is achieved by using a photo-transforming membrane supported by a light-weight, luminescent, portable and easily-assembled without tools frame. The components of the apparatus can be efficiently and compactly packaged, suitable for mass distribution. The membrane has photo-transforming qualities which transform UV-light into a bandwith of light that promotes photosynthesis. This, in turn, enhances crop growth and increases internal ambient temperature.
