|Greenhouse Width (ft)||Approximate Height (ft)|
You can use longer ground posts if you want a higher greenhouse height. For example, if you are building a 12' wide greenhouse and want a height of 8.5' instead of 6.5' , use 4 ft ground posts instead of 3 ft ground posts. This will allow you to insert the bent poles at a higher position off of the ground.
