I have an 8' x 18' green house on a deck with removable polycarbonate walls for summer and an extra plastic liner for winter. There's a few extra unheated square feet where I grow cool growing plants or store dormant plants. I designed it and built it with my SO. The walls are painted 1" x 3" wood frames with the polycarb attached. I used six mil. plastic on the deck boards and a good grade of indoor outdoor carpet (but still under a dollar a s.f.). It was supposed to be a temporary solution but four years later is working perfectly. I inspect the plastic and decking below each summer. I've had accidental floods a few times and was able to remedy the situation with a carpet shampooer to extract the water. Water goes on the floor but recycles in the air and humidity stays at 60-80%. If it goes higher I open the doors on to the house solarium that adjoins the family room and enjoy the extra humidity. I water almost daily. That said, aside from a small collection of hoyas, all my plants are orchids and most are mounted specimens. The watering is automated for when I am away but otherwise I hand water. There are two small heaters and fans. Temperatures are stable enough to grow and bloom finicky hot species orchids though we have many below freezing days. Including two pics from November, 2011.
