The greenhouse seems very sturdy. It took my husband a few days to put it together since the instructions were very vague, there are no steps, just pages of pictures that you have to interpret. There were a couple of errors but we figured it out. Also we bought an extension as well which meant some confusion in the instructions as well since they are all pictured without the extension. I do wish that the instructions had mentioned that you have to tape all the panels BEFORE you start building it, there was no mention of it in the main instructions so it did not get done to our greenhouse which means we will have to take it all apart to fix.
ACF Greenhouses: Thank you for your review and picture! We are constantly working with manufacturers to help them improve their products and instructions for using them. Feedback from customers like you helps us know what areas need improvement. The
tape for the poly panels is optional. It is not covered in the Grow More instructions, because the tape is an aftermarket product you can purchase for the greenhouse. However, in the tracking email for every order, we do ask customers to please open and read the red envelope first because that is where we include additional helpful information for the products your ordered.
