I am going to erect Bubbles' temporary greenhouse this year on the side of our garage. It won't be very wide or long but it will take the stress off the space in the garage. Some of our plants have gotten really too large for the garage. I wanted to use thick clear vinyl but the price per foot is expensive. I found this on Amazon to use as the cover. What do you think?? The windows will allow some sun to come into the greenhouse. Depending on how far it will reach will depend on whether I use it sideways or lengthwise. Either way, light will get through. It also has ties on the sides to help anchor it down to PVC. Now, to work on a doorway...
