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.
