well I stared building my small but walk in green house. I used one of my raised beds as a 1/4 wall for one side(it is 2 feet tall),2 cattle panels these are (16 feet x 4 feet each) clear plastic to cover,bull dog paper clips (20+) misc scrap lumbar for the door. I will take pictures and post as the process happens. my total cost is under $200 dollars for the materials. the biggest expense is the cattle panels at $90 for 2 of them. pictures to come later today.
thanks for the link! this is such a cool project. I have a couple of cattle panels that I am going to arch over a raised bed to get my squash and small melons away from the ground and slugs. I know that I can't manage putting a door in it but maybe I can drape some plastic over it to extend my season. (a faux greenhouse) LOL
the plastic will keep the temps above freezing all winter so things like lettuce and leafy greens can grow all winter even with the snow on the ground and it allows the sun/heat to pass threw. they can get very hot in summer months but the fix is to open an end up.
