Precautions For The Construction Of Film Greenhouses

1. Determine the position of the marking. Use a meter ruler to measure from the lower end of the vertical column, the specified height is 1.5 meters, and it is clearly marked with a water pen.

2. First bury one of the columns in the first row and make sure the depth is 55 cm. Don't forget to put bricks at the bottom of the column.

3. Pre-dug the last row of column pits. You can dig deeper, about 60 cm, and put the column into the pit. One person holds one end of the ultra-flat hose and leans it against the marking of the first row of columns, and the other person holds the ultra-flat hose with the other end also leaning against the marking of the last row of columns.
