I came across this greenhouse made of windows the other day and was pretty impressed with what people are able to do with recycled materials. Reddit User HrairooHare states that the most expensive part was the six yards of cement which cost around nine hundred dollars, followed by the metal roof which was eight hundred dollars, lumber which was seven hundred dollars and miscellaneous items of three hundred dollars.
You can see their slideshow of the construction process below.
So if you have a window company near you, take a moment and see if they have any spare windows that you can use to build your own pretty sweet greenhouse.
