Abstract
A micro-climate temperature control apparatus for heating and/or cooling of plants is disclosed. The apparatus includes an array of flexible, individually movable plastic tubes which are positioned under the plant root systems and/or used as space heating and cooling elements proximate the plant foliage. The tubes are preferably formed of EPDM plastic enabling their use with high-temperature water sources, as well as conventional sources. A notched tube securement strip is also disclosed which enables arrangement and securement of the individually movable tubes in a wide variety of configurations and also facilitates the use of relatively short input and outlet distribution manifolds.
