This step by step diy project is about mini greenhouse plans. If you want to build a learn more about how to build a small greenhouse for several post, this project is what you are looking for. Follow the instructions and pay attention to the diagrams, even if you are a beginner when it comes to woodworking.If you don’t waste materials, this projects requires materials that costs under 20 dollars. Check out rest of the greenhouse plans on our site.
You should always plan everything from the very beginning, in order to prevent costly mistakes and to save time. In most of the cases, you need a friend to give you a hand when assembling the garden mini greenhouse. Invest in high quality lumber and plywood, as the components will be exposed to bad weather. Protect the components with appropriate paint or stain.
There are a few tips that you should take into account, if you want to get a professional result. Therefore, take accurate measurements and use professional tools when making the cuts or when drilling pilot holes. Align the components at both ends and add waterproof glue to the joints, if you want to create a rigid structure.

How to build a mini greenhouse
The first step of the woodworking project is to build the frames for the mini-greenhouse box. As you can easily notice in the diagram, we recommend you to drill pocket holes at both ends of the short 1×1 components and to secure them to the perpendicular components using 1 1/4″ screws.
After building the two frames, you need to assemble the box by fitting the vertical supports. Drill pocket holes at both ends of the supports and secure them to the frames using 1 1/4″ screws. Add glue to the joints and make sure the corners are right-angled.
Build the rafters for the greenhouse out of 1×1 lumber. Cut both ends of the components at 45 degrees and lock them together with 1 1/4″ screws. Pre-drill the components before inserting the screws to prevent the wood from splitting.
Next, build another frame for the base of the lid. Align the edges with attention and check if the corners are square.
Continue the project by assembling the lid for the mini-greenhouse. Drill pilot holes through the rafters and insert 1 1/4″ screws into the base of the lid. Drill pocket holes at both ends of the top ridge and insert 1 1/4″ screws into the rafters.
Fit the lid to the wooden box and lock it into place using two hinges. Before attaching the hinges, you need to cover the structure with vinyl sheets. Use hot glue or staples to lock the sheets to the frame of the greenhouse.
Last but not least, we recommend you to take care of the finishing touches. In order to get a professional result, fill the holes and the gaps with wood filler and let it dry out for a few hours. Check if there are protruding screws and fix this issue, if necessary.
