bwright I used the Dual Lock today to secure 4 acrylic "storm windows" to some north-facing aluminum windows today, and this stuff is the real deal! Backing comes-off easily, tape applies well, glue holds strong. I could slit the tape easily w/a utility knife where it was too wide. It holds the 0.100" acrylic very well; my wife and I give it four thumbs-up! Tho I haven't tried it yet on our GH polycarb panels, I'm certain it will work great to keep panels in place, even ours which are secure but which "rattle" in a wind. It will be nice to secure these at the tops and the bottoms especially. Go to fastenation.com for a good deal on the tape. >Posted by pcdur (My Page) on Wed, Jan 10, 07 at 13:16 >I cant tell how you attached your shelves to the back wall and side wall on the backside of your shelves The ~24" EMT conduit pieces that attach to the back wall do so via 1" L-brackets welded into the ends of these pipes (12 places in all). You could drill and screw the L-brackets also I suppose. The cattle panels just lay on top of the pipes (I tied them down in a couple places w/galvanized wire) and in the back corners I had to get creative--in several cases the panel is simply supported with screws, in others I had to put-in some brackets. Maybe I will post pics sometime, but these ain't particularly clever or pretty.

hi, its been a long time, but i would love to see the pictures from your build! my HFGH just arrived today and I'm so excited to put it together without crying! Your profile on photobucket is set to private, would you mind sending me a link? thanks!

Hi Carol, I bet you are loving having the 2 HFGH joined together. The one I have quickly filled up with my tropical plants in no time. I actually have had to overwinter plants at my mom's house because I ran out of room! LOL She's ready for me to get the greenhouse done. :) My husband plans on doing some work on it this evening since it's not raining right now. I think he has it in his mind how he's wanting to join them together, something like you did I believe. I won't be having doors at both ends since we are putting the gas heater and exhaust fan on one end. That was the reason that my DH allowed me a third GH now, so he wouldn't have to move the heater & fan later on down the road when I say that 2 aren't enough. :0) He's knows me well! I'll be sure and ask any ? if we get stumped on joining the three. Thanks for offering. Hi Barb, You will love having a single door on the harbor freight. What a pain those sliding doors were! If they weren't coming off of the track when I was trying to open them, then the wind was blowing them open. And where the doors met there was always a small gap between them. I love my greenhouse now, but it will be even better when it's bigger. Too bad you will have to cut down your maple tree. But in the long run you aren't going to miss it that much. ;) Amber

gardenerwantabe - I agree with your point. We built it on the driveway so we would have a flat surface near tools and power. The debate is now on as to the permanent location to which we will move it, which have been thrown into flux due to gato's wind issues. She wants it over in the corner where it will get direct (and sometimes very hot) sun - I am proposing a location between some trees where it will have some shelter from the wind, and a bit less direct sun. I won't install either the corner bracing, or any other enhancements such as angle aluminum across the doorway or 1/2 EMT across the mid-sections until we have the GH sitting on footings at a permanent location. Then I will add all of that to stiffen and secure the unit. 2 questions: We are in Mount Shasta, CA which is snow country (3500' elevation) and the snow can tend to be fairly wet and heavy. We had as much as 3' accumulation in some areas of the property over the past winter during some storms. Obviously I should remove snow from the roof if it accumulates like that, but I'm thinking about establishing some structural support along the roofline - either directly beneath the ridge, or adjacent to the #30 braces that are installed in the roof. Those supports would be probably be 2x4 or 2x6 lumber, supported by wood posts down to the ground. Does this seem a good idea, or unnecessary? In an earlier post, I raised the idea of setting the GH on top of 2x12 PT fir, so that it would sit on a footing like this: I see that you set your's on 4x4 PT. My thought is to raise the GH in this manner so that when snow is on the ground, at least the first foot of snow accumulation would be against the wood foundation. I realize this means a step up and over the threshold. Any thoughts on this? Does anyone believe that this amount of wood foundation, or possibly more, would help in terms of withstanding snow accumulation? Would the additional height raise any other issues concerning the effectiveness of the GH? Thanks, Greg
