I called my local store today to enquire abvout the 8x10, and this is an internet only item. It costs 499.00. I am seriously thinking about buying this in place of my 6x8 that was destroyed by hail. I also think I'll take the panels off during the Summer when it is not is use to help protect them from deteriorating. James

Hi Chuck, I love my HFGH 10x12, but I think splitting it in two to make a 5x20 lean-to would require a huge amount of rethinking and re-engineering. The roof pitch in the kit is predetermined by angle brackets at the corners, and by a formed angle in the framing piece at the top of the side wall; I don't think you could use that major component if you changed the roof pitch. The framework really doesn't lend itself to cutting the structure in two as far as critical bracing. Not saying it couldn't be done (anything is possible for hard workers!) but personally my husband and I think you'd be better off to consider building your own structure (which would allow you to go wider than 5' if you wanted.) It's nice you will have a solid structure to anchor to. I now know the twinwall polycarbonate panels that come with the HFGH kits will not last more than a few years in my own sunny climate, due to (in my opinion) a lack of UV protection, even though HF continues to advertise otherwise. The panels represent a huge part of the value of the kit, since true UV protected twinwall polycarbonate is expensive, so I now advise folks to take this into consideration, depending on climate, when they consider the kit. Some of the close-up photos in my blog may help you see what I mean about the pre-formed angles in the aluminum framing at the GH corners: Mudhouse blog for 10x12 HFGH Also, here's a link to a helpful site with many links to info about building your own greenhouse: Free plans for building greenhouses and solar spaces I also agree, I'd encourage you to start a new thread to get more opinions from other folks...lots of folks here more knowledgeable than me, and some of these older threads with many slow-to-load pics get skipped by folks who might be very helpful to you.

Thanks Karenrei. I use propane to heat my very remote "cabin on a lake", and it's fine there because a local farm business will fill a 100 lb bottle for only $40, and the cabin is well insulated. Soon I'll have a 250 gallon tank and the gas truck will simply keep it filled for even less per unit of LP. I just sort of hate to have a couple of propane tanks to fuss with (and hide) when I could go to the trouble and cost to bury a 100 foot gas line from my house to the greenhouse. I'll basically have to trench it anyway to run water and electricty. I know that propane produces CO2, but it seems that not all experts agree on the benefits of even THAT! Really... I'm just not sure if it might be just as cost effective to use electricy, since I have no experience on what it's going to take to minimumly heat an (obviously) uninsulated greenhouse in this area. Ahhh the mysteries.... but I sure appreciate all the help and advice! I have a decent background in greenhouse gardening, but I've never had to heat one until now. I moved here for a good reason... but every winter I cannot remember WHY! jim Palmer

I had one of those Harbor Freight 10 by 12's it was quite sturdy but the glazing did not have any UV preventive coating and it yellowed in a year. I don't know if they ever addressed that issue, I know I had it a year before I realized it and the warrantee was up. Check to be sure the glazing panels are treated while you have a warrantee.
