Enclosed structures

A plastic-covered, gutter-connected sheltering horticultural structure essentially constructed of a framework and flexible cover sheet material, said sheltering horticultural structure comprising:

• a plurality of gutters (18) each having a bottom wall and two side walls forming a concave channel along a length of each of said plurality of gutters;
• said each of said plurality of gutters (18) being parallel to each other and supported above ground by a plurality of spaced posts (10);
• each of a plurality of arched roof trusses (12, 16) connected at their ends between one of said two side walls of a consecutive pair of said plurality of gutters (18);
• at least one anchor means joined to each of said plurality of gutters (18) for detachably engaging longitudinal edges of said flexible covering sheet material and maintaining said flexible covering sheet material in a tensioned state over said plurality of roof trusses (12, 16);
• said at least one anchor means being located over and within said concave channel;
• a plurality of fastening means spaced at intervals along a length of said each of said plurality of gutters (18) for engaging and maintaining said one of said two side walls and said anchor means spaced apart to provide unobstructed passages between said anchor means and said one of said two side walls;
• wherein condensation fluids generated within said structure travel down an underside of said flexible covering sheet material, over said anchor means, through said unobstructed passages into said plurality of gutters (18);
• and
• fluid precipitation generated exterior to said structure falls on said flexible covering sheet material and travels down directly into said plurality of gutters (18).
