I bought the 10X12 HFGH and it is up. I dug a hole and placed the base frame in it and filled it with what we call red breeze. I did have a bit of a problem with the instructions. I went to HF web site and downloaded a new set of instructions. That helped, but even with these new instructions, it left a lot to the imagination. They were different than the ones that came with the GH. I do want to make some modifications to our GH also to make it stronger. I am new to this site and would like to know how to find pictures on here, especially of the pool cover for insulation. I am thinking of putting up bubble wrap on the inside to help with insulation. I found these items on EBAY. Greenhouse Insulation Fittings - Super Alliplugs x 50 Has any one tried these? Here is the link to his EBAY store. Looks like lots of parts we could use on our HFGH. http://stores.ebay.com/Greenhouse-Warehouse He is located in UK, but the parts look exactly like what came with the HFGH, if you need extra parts.

Just a quick note under WOW Coupons, I typed in Harbor Freight Coupons and this was one of the selections. There is a 20% off coupon on anything from Harbor Freight through May 30,2009. I don't know if it is any good; but, this is how I got my coupon. I printed it out and took it too the store. The manager even asked where I got it and I said on-line. They didn't blink an eye and gave me the discount.

This greenhouse was bought 2.5 years ago. I am a construction guy and put it up reinforced with 2x4 on the inside and extra screws in every panel. I did that because everyone was having a problem keeping them up. Well the wind never blew the building down but the doors came off the hinges with every storm...even after trying to secure it closed. The big problem was that after 2.5 years, all of the roof panels begin to crumble...and with a little wind they would crack and bust, then fly off. I called harbor freight and they said they could sale me panels for 41 dollars a piece. That times 12 is almost 500 dollars....I bought the green house on sale for 600. The panels will only last another couple of years and then it will be the same thing all over again. Please, please, don't waste your time with this. If I knew this about the roof I would have never bought it.

Sheri, WOW, what an awesome project. And the time and effort to document it the way you did will surely help many folks through a very difficult construction project. OH, so many, many, years ago when I was still in the USN, I had redwood and fiberglass house that was about 8X10 feet. I grew orchids in SC, KS, FL, and VA in that little thing. We lived in a mobile home, so the greenhouse got disassembled and put in the home for transport, and the orchids traveled in a rented U-Haul. A couple of things I learned the hard way (you learned some of them also, I see) was that you need more shade than you ever imagined. I suspended my shade cloth above the plastic greenhouse (about 4 inches) and found that the air space actually increased the shade effect, and noticeably decreased the heat load inside the house. Another thing that would be difficult for you to do since your studs are so shallow, and metal, would be to double insulate the house. Mine had 2X4" supports that were wood, so I stapled painters sheet plastic on the inside, trapping four inches of dead air in the walls. You can't purchase better insulation than that, and it gives you a way to mount your electrical boxes away from the direct spray from watering. Another approach to cooling was to use a "Swamp Cooler"....to you westerners, an evaporative cooler. Mount the cooler on the ground outside the house and let it blow the cool moist air into the house. Cool moist air stays low, and the hot dry air is forced out the top vents. the vent opening at the top can be used to regulate the cooling inside the house. Also, I found the positive pressure in the house helped keep bugs outside. I don't know if HF sells different size houses, but I always suggest purchasing the largest house you can afford. The more inside volume of air you have the more economical the house is to heat and cool. Once the air gets to temp, the more of it there is the longer it takes for it to change temp, which means more time off for the heat and cooling. These are a few of the things I learned in my school of hard knocks, and pass them along for information to anyone who is interested. Bill
