The greenhouse is used for growing plants from seed.The objective to have strong healthy plants for the outdoor garden starting about 15 of April for some seeds and plants. Tomatoes will be planted about 24 of May. The outdoor temperature at night is usually slightly below zero. The little greenhouse keeps the plants above freezing.The real advantage is the sunlight available.

I decided to build a large greenhouse on the deck, which doesn’t get much use. The enclosure will be a sun room if appropriate, instead of the canvas structure that use to be there. I have a small 10,000 BTU heater that connects to the barbecue natural gas outlet, so will have some warmth, and will get some use during the Winter months. It took nine days to build by myself, about 72 hours of labor, from 28 of October to 5 November, and cost $1798.63.
Description of the construction. Six, 6 by 6 pillars support the structure. The auxiliary supports are all 2 by 6 spruce planks. Two doors were installed plus a window to ensure reasonably good ventilation. I got the doors free of charge. The slope of the roof is from 8 feet to 7 feet, with a pitch of 1 in 12. Sun is available for about two third of the structure all day. Wood was used to cover the walls where no Sun penetrates. Corrugated SUNTUF UV protected panels was used. It is relatively low cost compared to other coverings, and is almost indestructible. Pictures depict highlights of the method used. Plans were in my head.
