I am planning on building a greenhouse. What kind of wood should I use for a greenhouse? There are many types of wood that can be used to build a greenhouse, but some woods are better than others. Cedar, redwood, and cypress are all good choices because they are naturally resistant to decay and insects. If you choose a different type of wood, make sure to seal it with a waterproof sealant every year to protect it from the rain and snow.

There are a few different types of wood you could use for your greenhouse, but redwood and cedar are two of the best options. Both woods are resistant to rot and decay, and they also have a natural resistance to insects. Cedar is a little bit more expensive than redwood, but it's worth the investment since it will last much longer.
