I'm wondering what became of the dog? I took Blue (the chicken killer) to the HS and paid a fee for being out of their county. They told me they would not put him down and they shipped animals all over trying to get them seen and adopted. He would make someone a nice dog, very affectionate and loyal. They did make a notation about not placing him with small animals and actually his actions disqualified him from a local program where they retrain labs and goldens for the disabled. They called it "small animal aggression." Blue was fine with the cats until they ran from him (which was always since he never walked anywhere, always a dead run). He wouldn't just attack them but it was coming, I could see. I never knew how traumatized the cats were, staying in the garage all the time. Our oldest cat, Tigger, was very frail and ill looking and I figured it was his 15 yrs of age catching up with him. This spring since Blue is gone, Tigger is again beautiful and healthy and enjoying the outside. I have 7 little hens that escape the pen and free range each day, they are just small enough to squeeze under the corner of the pen. I so enjoy seeing them around the house and sneaking into the garage! I say sneak because they know they aren't supposed to be in there but I usually leave the back door open for airing the place out and they go in and eat the cat food, LOL! I have 5 guineas in a pen in the barn and plan to let them out in a few weeks. I could never have enjoyed all my critters with Blue around. Heck, I probably wouldn't have been able to even garden since he was just so distructive. I have been wondering how you dealt with your problem dog. Judyag, were your Great Pyrenees already grown? I have just heard such good things about these creatures! I would like to look into getting one or similar guard type dog for our place. Lori

Best way to post pictures and to have a place to just keep pictures, is at www.photobucket.com When you get there, you'll see that it's very easy to make albums and upload your pix. Once uploaded, you see 3 fields below each picture. You cut do a copy of the middle one ("Tag") and simply paste it here. That's it. For example, our greenhouse last winter's tag is: (note, I've just added spaces to that it won't actually display the pic) When the above, is pasted here (without the spaces of course) you get this: IMPORTANT TO NOTE: If you change anything about the photo's location, it will no longer display here.

The whole idea of air exchange once a minute is good and it's a common practice, but my experience is that this is not sufficient for high intensity sun and single layer glazing. I installed multiple additional vents to get natural ventilation going before the fan kicks in. I want to grow vegetables to save money, have more variety and better food, but I don't want to be paying for it through higher electricity costs. Venting is done with a fan and vent for most of the year, and then I am relying on manual venting for the summer. Since you are building this from scratch, you also have an opportunity to install underground heating with Pex piping. This can be coupled with solar panels or a water heater of some sort. This type of feature is installed in all three of my greenhouses, and it makes a big difference in getting a jump on the season and extending the season. One concern I would have is installing overhead glass. It's heavy and potentially dangerous. Have you considered glass walls and a poly roof?

I'm no expert on greenhouses but I'm guessing the materials you choose will depend on location of the greenhouse (wind/rain/snow) and how much you intend to use it. How many plants do you have, and are you wanting the greenhouse for future plants? Corregated panels work well but if you're in a high wind area be prepared for damage and noise. For longevity, I would consider glass panels. You could check salvage businesses for glass panels or glass doors to use as your walls and you'll also need some type of window/vent to open during warm winter days. As for the GH also being a catio, I'm not sure how much the cats will use it during the months you have clear paneling up. Clear, plastic paneling isn't really that 'clear' and if cats can't see out one would think they'd have no interest in spending any time out there. You may want to consider 2 structures.....one attached to the house for the cats and a separate building for the greenhouse. I have a catio on my deck that attaches to a cat door via a wire tunnel. The catio is a 6x10 dog kennel with reinforced mesh for the roof. Fortunately we have a covered deck so we didn't have to build a solid roof. I'm in the Portland area and my cats use the kennel year round.......avoiding it only during the windy, stormy days. The insects, crows, other birds, deer, etc keep the young cat entertained while the senior cat sleeps. :).
