Hi Steve, To address your original questions about soil heat cables.......we live in a very cold climate here in Wyoming at over 6,000' elevation with winter temps as low as -40 degrees F. We have not used soil heat cables in an outside grow box - but did decide to experiment with a grow box inside our unheated GH. We bought the cable length we needed based on the area we wanted to cover - 30" X 96" and according to the spacing the cable manufacturer recommended. We followed instructions and mounted the cable to 1/2" hardware cloth and then mounted the hardware cloth to cattle panel for extra stability and ease of moving/storing. We purchased a thermostat and set the temperature at 55 degrees F and placed the cable buried 4"s in a raised bed within our GH and made a polycarbonate cover to create a box with lids. We tried to grow salad veggies during the winter months - November thru March. The daytime temps in the GH on a sunny day were between 30-70 degrees F even when OS temps were 0 degrees F so I would raise or remove the lid during the day and cover the box at night when OS temps were as low as -30 degrees F and IS GH temps as low as around 0 degrees F. The soil heat cables were usually only running during the night so I did not notice much difference in our electricity bill. The photo below was taken on January 31st. We are in Zone 3 where danger of frost remains through June 1st and there is snow on the ground usually through April but we have had snow and frost in every month of the year during cold spells. I think most would agree the experiment was a success! The cons in my opinion is the cost of the cables, wire and thermostat and the daily covering/uncovering of the lid (although the polycarbonate only needed to be removed on sunny days because of the heat build-up). When I retire I may do this every winter but for now - it is nice to have a winter break from the GH. We also use the Soil Heat Cable as a germination mat on top of the soil in the GH in February - March as an overflow box from our inside grow lights - that works well too. We are building grow boxes this year OS for our squash and other warm weather plants and appreciate your design!

I really like the one-piece Toto I have - easier to clean, sleeker lines. I will never ever have to battle a leak between toilet and tank the way I have my other two toilets - both taken apart and put back together with new washers and gaskets two or three times before they stopped leaking. It really isn't that heavy or hard to install. You don't need two to lift it. My big strong son carried it upstairs for me; he held it up while I guided it onto the bolts. And when I wasn't satisfied with the placement I picked it up myself to re-seat it - I'm a small, middle-aged, not in shape woman - I wouldn't have carried it upstairs by myself but I can certainly pick it up. Use your legs, not your back! Unless I'm going for an old-fashioned look, any future toilets I deal with will be one-piece.

We have a Champion 3 season sunroom. We live in Indiana it is blistering hot or freezing cold here. And sometimes all within the same week. It was pretty expensive. We thought we would be able to use for at least 3 seasons . No if it is too cool( in the 50s ) and you use heat, it sweats. If it's hot outside. You can't afford to cool it. As it leaks air so bad. We fight wasp out there all the time. And you can't have nice furiture out there because of all the dust. ( we live rural )Ours has turned into a dream turned night mare. I would put my money into a conventional room addition. I wish we had. Now we are trying to decide if we should try to salvage the floor and rebuild the walls and roof ourselves. Or call it a wash and tear the entire thing down. Good Luck with what ever you choose.

Living in PA, we have a 60's built ranch home with no ductwork. My husband had one of these systems put in this summer (Fijitsu wall mounted system) to cool our main living area. It works great. It is quiet and works very well cooling most of the house although we only needed it for living/dining/kitchen. I had hoped for the best when I reluctantly agreed because I HATED how it looked. I had seen these units in other peoples homes and hated them then. People (especially contractors) assured me that I would get over this. It has been since June and I still hate how it looks. When friends and family (admittedly mostly female) see this unit, their first reaction is negative on how it looks. They try to be nice about it but when I ask their honest opinion, they say it is ugly. I really regret having this installed. The few short months that we use it was not worth the eyesore it is in our house. I am trying to come up with ways to hide this beast for the 8 or 9 months of the year that we don't use it. I am writing this only to forewarn anyone who has concerns about installing these units because of the looks. My advice would be if you have white walls and high ceilings, then this would likely be less noticeable. If you have lower ceilings like I do and have a wall color other than white or light, this is going to be noticeable. Also, I would suggest do whatever you can to find a wall that is not a focal wall to install this beast. My was installed on a focal wall which only adds to the problem.
