I brought one, it's just sitting in the garage, still in the box. I either need to sell it or assemble it, and if that's the way to go, I could really use those instructions.

Thanks

Many folks at this forum (myself included) believe that it's risky to build the kit as per the manual, without any further reinforcements, if you want to avoid problems caused by wind damage. This forum has many posts with excellent tips regarding these reinforcements, and they were a life saver to me as my husband and I built our HFGH. I tried to many of these assemble tips in my blog:

Here's a list of helpful links I've saved, posted by other folks who have assembled this greenhouse. They're all worth reading, and I'm sure you can find more, by doing a search for "HFGH 10x12".
