Great pictures! Fortunately, the tree in our way died about a year before we put up our greenhouse (still had to cut it down, though!) We had a furry OSHA inspector too (all extra paws and hands were greatly appreciated.) I love my 10x12 HFGH, enjoying it for my third year. It's totally stuffed with plants, year round. "- We will add more clips to prevent the panels from flying off in the wind - a major concern." Sounds like you've read the archived threads here about the recurring problem of lost HFGH panels. In addition to extra clips (we did that too) it's pretty easy to add self-tapping screws to the panels, as even more protection against panel loss. The 10x12 is pretty tall and makes an even worse target for wind damage, but there are some scary threads archived here about wind-damaged 6x8 HFGHs as well. Here are some photos showing how we screwed the panels into the aluminum frame (thanks to previous GardenWeb forum members who suggested this improvement.) Part Six, Adding the Panels "- Depending on the temperatures, may add a blind on the western end to prevent sunburn and excessive late afternoon heat." I definately need shadecloth on the roof, west end, and south side (my succulents and cacti cook in there without it.) I also believe that adding shadecloth has helped to increase the lifespan of my HFGH panels in our sunny climate. (I used Aluminet shadecloth.) Some GardenWeb HFGH owners have reported problems with the HFGH panels deteriorating after exposure to sun, but others don't seem to have this problem. My panels have yellowed, but I see no other signs of deterioration (fingers crossed.) "In winter, may add water jugs as heat sinks in cooler weather." In theory it seems like this would help, but the general consensus seems to be that you'd need very large containers of water to retain enough heat to truly benefit you into the wee hours of a cold morning. Most small greenhouses can't afford to give up the high percentage of space required to make this work, but there's lots of good reading on this topic in this forum (posted by folks who are much smarter than I am.) "- Wish list: shelves, solar fan, temperature activated window control" Just a warning, the HFGH solar fan is not powerful enough to adequately cool your greenhouse (sounds good, but doesn't quite work.) If you do a search in this forum for HFGH solar fan, there's a thread with a knowledgeable poster sharing his calculations that a 6x8 HFGH would need three of the HFGH solar fans to exchange enough air to drop the temps (if my memory is right.) There are also some posts from folks saying the HFGH vent openers don't last long at all, and it's best to research and purchase other brands that have a better track record. Good job, congratulations, and happy greenhousing! Sheri

google what Jucelino Nobrega de Luz has to say about our weather. (you'll have to use 'translate this page'. If you want, I can send you a document ;)

I have also been observing the heat tolerance of my passiflora's. Mainly with my tacsonias. X exoniensis, manicata 'Linda escobar', and 'Susan Brigham'. They seem to grow fine if dappled shade to bright shade. They get morning sun for a few hours and then an hour of light just before dark. When that 1 hour of late afternoon sun hits them the top 6 inches of growth nods down and wilts but once the sun is off of it they perk back up. They are still growing very fast but did drop the flower buds. We had a few days of 105 F and the buds dropped instantly. Hopefully they will resume blooming in the fall.

Hannah - Sorry this is late and also a little off the cuff. If I were in your shoes looking for a suitable process without sinking a lot of money into this project, I would consider putting the entire pile outside and adjacent to (or piled up against) the north wall of your greenhouse. Cover it with foam board insulation so it doesn't cool off too quickly. That would get rid of the moisture problem, increase useable space inside, and likely help with the smell! Then run the garden hose through or under the wall and into the pile. I think garden hose would work fine at least for a few years. You'll need some sort of heat exchange inside. A very simple one would be one of the black tubs. A submersible pump pulls water out of the tub, through the pile and then drains back into the tub. This way you would be extracting heat but it wont be extremely cold water going into the pile (thereby hopefully reducing the chance that you could 'kill off' the composting process). I imagine theres some way you could get the thermo siphon / convection effect working but I just cant help there. I think having mechanical control of the flow is better. You could try using one of the many solar powered fountain pumps sold online. The problem with those is unless you get or build a battery charging system it will only run during the day. You'll want to make sure to minimize the amount of head pressure (height that the water needs to travel) with these pumps as they typically do not have real good pressure ratings. For tape, maybe get some that is specifically made for greenhouses: http://www.greenhousemegastore.com/product/poly-patching-tape/polyethylene-film-install-accessories I think gorilla tape makes a clear version now too... that's probably what I would try first.
