This invention is directed to a plastic-covered, gutter-connected sheltering horticultural structure constructed of a framework and flexible cover sheet material. The structure is constructed with a number of gutters with arched roof trusses connected at their ends between side walls of a consecutive pair of the gutters. Anchor means are provided to join each of the gutters for engagement to longitudinal edges of flexible covering sheet material and maintaining the sheet material in a tensioned state over the roof trusses. A plurality of fastening means are spaced at intervals along the length of the gutters to maintain the anchor means spaced apart from the gutters to provide unobstructed passages between the anchor means and the gutters. This permits condensation fluids generated within the structure to travel down the underside of the flexible covering sheet material, over the anchor means, through the unobstructed passages into the gutters and fluid precipitation generated exterior to the structure to fall on the flexible covering sheet material and to travel down directly into the gutters.
