- Mark the footprint for your greenhouse with a ruler. This plan calls for a 6-foot-by-8-foot rectangle.
- Use the post digger to dig a 2-foot-deep hole at each corner. Mix the cement and fill each hole. Place the two 5-inch-by-8-foot poles on one 8-foot length of the rectangle, and the two 5-inch-by-6-foot poles on the other 8-foot length. Use stakes, twine and a level to keep these poles perfectly vertical while the cement sets.
- Place one 2.5-inch-by-8-foot pole at the base of the 8-foot-long sides of the rectangle to begin framing the bottom of the greenhouse. At the intersection of these poles with the vertical support posts, drill a 1/2-inch hole between each pole and then secure them together with a 1/2-inch nut and bolt. Repeat for the other end of the pole, and then repeat this same step for the other 8-foot-long section of the rectangle.
- Repeat Step 3 for the 6-foot-long sides of the rectangle using the 2.5-inch-by-6-foot poles.
- Take the other two 2.5-inch-by-8-foot bamboo poles and mount them at the top of the vertical poles on the 8-foot-long sides of the rectangle. Secure with nuts and bolts at each corner as before.
- Use the 2.5-inch-by-6 1/3-foot poles to span the distance between the shorter sides of the rectangle at the top. The 2-foot difference in height will provide a slant in the roof so that water can run off easily.
- Wrap the entire structure with heavy grade clear plastic sheeting. Make sure this plastic is pulled tight to prevent slack, and secure in place with a staple gun throughout the inside of the structure.
How to Build a Bamboo Greenhouse
Bamboo is one of the most sustainable building materials currently available to eco-conscious consumers. As such, it can be a harmonious and cheap material to use when building a greenhouse. Experimental designs exist right now that use bamboo on an industrial scale in greenhouse building, but having a bamboo greenhouse in your backyard is a much simpler process.
