Build your own 9 x 12 greenhouse with these free plans for a barn style greenhouse. If you like to garden why be stuck with only summer gardening. By building a green house you are opening up months more of gardening and with some heat in your greenhouse you could be playing with dirt all year round.
There are lots of greens that you could grow year round with minimal heat. Pretty much all lettuces and spinach type greens will grow in cooler temperatures. I have seen some type of green houses that use water barrels painted black and then lined up along a back wall and then filled with water. The black barrels absorb what ever sunlight is available and this heats the water inside so then at night the warm water helps keep the greenhouse warmer through the night. How To Specialist shares free plans for a barn style greenhouse so you can build one your self and add to your growing season.
While these plans are for a 9 x 12 you could make it a couple of feet wider to allow room for the water barrels. I would love to grow food all winter and just to be able to putter around in the dirt and breathe the air where the plants are growing would be really nice.
