This step by step diy project is about10×16 greenhouse plans. This isPART 2of the wooden greenhouse project, where I show you how to build the roof and how to fit the doors and the vents. You can make adjustments to my plans and fit more vents or change their locations (for ex. fit the vents between the rafters). Take a look over the rest of mywoodworking plans, if you want to get more building inspiration.
