Well first I will have to figure out how to post pictures on this site. I just bought a new digital camera so I will take some pictures of the construction. If I don't put them here I can post them on the same site where I have pictures of my Corvette show car. I know how to upload pictures to that site. I was going to order two of them and put them end to end like several have done with the 6x8 but I just ordered one if it is not big enough I can order another one. My wife is the one that is into flowers I just do the grunt work for her. Between building the greenhouse and getting my car ready for the shows in the spring is going to keep me busy. All the wife will do with this is grow flowers from seed. I built her a water garden and it has flowers all around the ponds and it is pretty in the summer. Last few years I spent about $1000.00 a year at the local nursery for annuals to plant in the water garden plus all the perennials. The greenhouse will save enough to pay for itself besides the wife loves to grow them.

I bought one years ago so i can't help you with brand or current cost. But I bought enough in bulk to cover the top and front(south facing). I cut it into manageble pieces for 1 person. Sewed on edge fabric(to protect all edges) and installed my own brass grommets. I used a simple pulley system outside the GH for the roof area. I used j-hooks for the side(spaced approx 2ft apart). Mine are black,but the shading percent will depend on whats in the GH during the summer. sorry if this isn't much help. I start my new HFGH project tomorrow(foundation plan an layout).

MissAgnes, I doubt that you will be able to locate specific statistics for snow or wind load for the HFGH (and I am very doubtful that Harbor Freight has this info, or will attempt to estimate it for you.) To be honest, their focus is not on long-term durability; it's on selling as many inexpensive kits as they can. The rest is up to us, as HFGH owners. I honestly have no idea how this might be calculated for the modified greenhouse; I can tell you that we estimate our modified greenhouse has handled wind gusts over 50mph on numerous occasions, and possibly a few 60mph gusts in the last six years, with no damage. However, our greenhouse is sheltered on the north side by our house, and we don't have any monitoring equipment, so this certainly isn't any kind of scientific evaluation. My guess is the wind resistance of the Harbor Freight greenhouse, built out of the kit, with no modifications, is ridiculously low (laughable.) In my opinion, it's almost certain to fail; it's just a matter of how much time before the event happens. There are many old posts here with sad tales of those who have watched their (unmodified) structure being permanently destroyed by wind. Also, many sad reviews on the Harbor Freight website, from folks who didn't know how critical the modifications were. Same story with snow load; I have no idea who would have exact figures, but I can tell you there are posts archived here of roof failures from snow. The weakest portion seems to be the center of the roof studs, so that's the area most folks focus on, when trying to build for snow load. I have gathered some links to older threads here regarding snow modifications, and they are posted in the Comments section of Part One of my blog (scroll down about 2/3 of the way through the comments at the page below, and look for the question posted by snwplwdrvr.) Part One, Building our 10x12 Harbor Freight Greenhouse Hope this helps!

Hi funnylady, Yes, we did... The important word to note here is 'did' :-( Not sure if you have heard of the horrible wind storm the NW had a few months back.... Well it hit here with a vengeance. Normal high wind speeds of 15-20 mph (and that is a wind storm! Usually it's abt 0-3 mph) was clocked up the street at 84mph. Good new was.... Greenhouse frame still standing... other good news... I was able to locate all of the panels, even though several were abt 5-7 acres away behind our barn or some in the other direction out at the road ... Basically all went together well, (except we had planned on changing the doors to hinged rather than sliders) and we didn't get around to screwing the panels down (although they were double clipped). Overall the GH fared winter well... rain, snow and ice were no problem... but those horrific winds, well that was another story... We were without power for abt 3 days and friends had nineteen 100'+ Fir trees that came down (we were lucky, only branches everywhere) all our trees held their ground. Not sure any greenhouse could have withstood that windstorm, but had we screwed the panels in as planned we might have had even less damage.... Ah well.... BTW panels were all fine... are installed and screwed in now... don't want to tempt fate, but think it just might withstand that huge storm this time....
