Need height of 6 ft

As I have a raised foundation, would it be easily possible to lower the height by about 2 feet?
Asked by: Lester
Because of the brass grommets, seems, manufactured frame and connectors, this request would not be easy.

8 ft. x 12 ft. x 20 ft. Round Top Commercial Greenhouse is rated 3.6 out of 5 by 8.

Rated 1 out of 5 by from Misleading product. We purchased this greenhouse with the expectations of having a weather tight frame. My husband puts together timber frames for a living and when he went to put it together as specified in the directions the cover was not large enough to cover the frame and create a seal where cold air could not get in. When he called the company saying that we probably received the wrong size cover for the frame provided as stated in the assembly directions we were told they would get back to us. They did get back to us stating that they understood the problem and my husband was right the directions are misleading. To rectify this problem they were going to change the assembly directions to reflect that WHEN YOU BUY THE LARGE GREENHOUSE YOU GET THE SAME SIZE COVER AS THE SMALLER GREENHOUSE. THEY ONLY MAKE ONE SIZE COVER. We lost all our tomatoes, peppers, flowers, herb seedlings when the temp got cold enough because there was no way to seal it up tight. Which makes it useless. The zippers are jammed and ripping We are going to remove the cover and use regular greenhouse plastic and build in a door on the end. So all will not be lost as we can use the frame.

Rated 4 out of 5 by from Great, but not that great!!! My overall impression is very good. However, there are some major issues that could be improved upon. (1) The instructions are very vague and it takes several tries to put the unit together. (a) The instruction booklet says that it will take 2 men about 2 hours to put together. (Untrue) (a) The pictures in the instructions are incorrect. For instance, the eyes that are supposed to be threaded around the bottom do not line up as if the skin is too short, and so the bar had to be raised in order to fasten the eyes of the skin to the bar. (the picture shows that it fastens at the bottom...if so, the string/rope is way too short to follow the instructions in the booklet). (2) The 4 ratchets that are included are of the cheapest design and quality. (There is a pin that locks the ratchet to the frame and its quality is very per the ratchet itself, poorest quality). (3) The 4 straps that are supposed to go into the ratchets are cut too short, making it nearly impossible to tighten the skin to the frame without pulling and pulling and pulling. (If only these had been at least 12" longer, it would have been a lot easier.

Rated 4 out of 5 by from Very Pleased With Purchase We invited family to "help" raise the greenhouse up so with four people it was a smooth set up..the zippers on the door and two vents are a we "zip" with care so as not to cause a problem with them as they get "older". We had the store order it for us and had it delivered to the store also which was great for us-overall very satisfied!

Rated 4 out of 5 by from Frame and tarp appear to be of decent quality. Time and Mother Nature will let me know!! Not the easiest thing to put together. Took my wife and I most of the day. I give poor grades to the instructional manual and it's photos. Having previously owned one that was very similar, thankfully gave us an advantage!
