    How to Measure Poly Sheeting for Hoop Houses


    1. Throw a rope over the width of the hoop house and pull the line taut.
    2. Next, mark a spot on the rope where the ground meets the side of the greenhouse.

                                      

     

    3.   Make sure to do this for both sides of your greenhouse.


    4.  Lay the rope out straight and measure between the marks.
