Disadvantages of High Tunnels
One of the primary disadvantages of the more permanent high tunnels is the fact that they are not easily moved. Some high tunnels are engineered to be (and advertised as) easily movable. However, they are typically not very easy to move, and many high tunnels are never moved
Another disadvantage to high tunnel production is the lack of exhaust fans for venting during hot weather. In most regions where tunnels are used, tunnels will overheat at some point during the crop production season unless manually vented, or unless an automated ventilation system is used to roll up the sides as the temperature inside the tunnel rises.
Another disadvantage of high tunnels is that they can be destroyed by high winds, snow, and ice, as they typically do not have the strength of greenhouse structures. Tunnels should be designed to withstand or avoid these stresses.

What are disadvantages of wind tunnel testing?
Wind tunnel testing is generally very expensive and time consuming. In addition, if the object to be tested (i.e. a car, an airplane) is too big to fit in the tunnel itself, a very accurate scale model must be produced, and Reynold's numbers (a number describing the flow conditions over the object) must be accurately matched to the expected operating conditions. These models can be prohibitively expensive as well.
