People who live in glass houses can’t throw stones, but they can use stones and glass to help their plants thrive.
There's no need to go out and buy a prefabricated greenhouse when you can get DIY greenhouse plans online, and it only takes a few tools and supplies to build your own.
How to pick the right prefabricated DIY greenhouse plan
Here are a few things to consider before you decide on a DIY plan.
Taking the time to find a prefabricated greenhouse that suits your needs can be a long and tedious process. Every manufacturer is different, and many greenhouses may not fit your space exactly how you would prefer. Researching and finding a greenhouse that will make sense for your style of gardening, as well as your backyard, is essential and can take more time than expected. Building your own DIY greenhouse will allow you to customize the building and add in extra items or take away design specifics that don’t fit your needs.
We should also point out that it is easy to replace or change the look of your greenhouse if you build it yourself. Trying to find replacement pieces of glass or plastic from a manufacturer can be a nightmare. If you make your greenhouse instead, you’ll be able to replace easily and tend to those small maintenance issues that are hard to do with a purchased product.
In general, usually DIY projects are cheaper than what you would spend on a prefabricated greenhouse. Building a greenhouse yourself allows you to use supplies that you have on hand without having to purchase much from the store. Many DIY greenhouse plans use recycled material as well as natural elements of your home and backyard that help to enhance the building overall. Purchased greenhouses can cost a few hundred dollars minimum making a DIY greenhouse a smart budget choice.
Ordering a purchased greenhouse may seem like the time-saving choice but consider all of the factors that you need to think about before buying. You’ll spend time researching the best prefabricated greenhouse for your backyard as well as shop around to find the best price. Also, consider the fact that many greenhouses still need to be assembled once they arrive at your home as many do not come fully assembled and ready to use immediately. Instead, you could have used that time to gather supplies and to build your own DIY greenhouse that is custom to your specific wants and needs.
Part of the reason why many homeowners choose to build their own greenhouse is to help support nature by using recycled and renewable materials. It makes sense to use eco-friendly materials to create a greenhouse that is meant to nurture and encourage plant life. Doing so allows you to build upon the idea of supporting the environment by limited waste and manufactured materials and giving new life and purpose to such items like old windows, lumber, metal, and plastic.
