2) Set up tunnels so the most prevailing winds hit the end walls and flow through the tunnels

3) Make sure doors are open and tied back during 30km/h winds

4) Vent the tunnels early in the day before the high winds, let the wind pass through

5) We growers know that the forecasted winds can vary considerably depending on location and micro climates. Adjust your tunnels according to your own site information

Taking a chance can prove to be very expensive.

30 km/h - open and tie doors

50 km/h - vent to stage #1 - 2 ft up from the top of leg

60 km/h - vent to stage #2 - 4 ft up from the top of leg

70 - 80  km/h - vent to stage #3 - 6 ft up from the top of leg

95+ above - de-skin, put film in leg row and tie ASAP before wind comes

This is a guide only. As you get more experienced as a tunnel grower these decisions will become easier to
make.
