An apparatus for growing vine crops in a greenhouse comprises a first media carrier, a first nutrient supply means, a first support means, a regulating mechanism, a main cable, a plurality of load differential mechanisms, a second media carrier, a second nutrient supply means, and a second support means. The second media carrier is above and in substantial parallel with the first media carrier. The distance between the first media carrier and second media carrier is adjusted by the regulating mechanism. A method for growing vine crops in a greenhouse comprises two growing modes: a single crop growing mode, and a vertical dual crop growing mode. The sequence of this process begins with a first single crop growing mode, followed by a vertical dual crop growing mode, and then followed by a second single crop growing mode. A single crop growing mode: first crops grow in the first media carrier fed by the first nutrient supply means, trained by the first support means. A vertical dual crop growing mode: the first crops grow in the first media carrier fed by the first nutrient supply means trained by the first support means; and second crops grow in the second media carrier above the first media carrier fed by the second nutrient supply means and trained by the second support means.

An asymmetric damping mechanism for use in a belt tensioner. The damping mechanism comprises two parts having substantially similar arcuate shapes for engaging a tensioner. The first part is in contact with the second part at a pivotable point of contact. The point of contact position is determined according to the desired asymmetric damping factor. The first part is also in contact with a spring. The second part is in contact with a tensioner arm. The damping mechanism also comprises two damping shoes, each having a damping band. The damping band is joined to the damping shoe by a plurality of vertical grooves on the damping shoe cooperating with a plurality of grooves on the damping band. The damping mechanism has an asymmetric damping factor in the range of approximately 1. 5 to 5.
