There are many overhead structures one could build; some cost more than others.
I chose this elegant design for my raised bed greenhouse.
In the end, it cost about $200 because of the cost of the polly sheeting.
What are the benefits?
#1 I can enclose the structure in the spring and fall to extend my growing season for several crops.
#2 I can control how much water my plants get to prevent inconsistent watering which causes tomato cracking.
#3 This can also help prevent diseases, such as, blight.
