Greenhouses are an excellent way to help extend your growing season, protecting plants from extreme temperatures and the elements, as well as for starting plants from seeds. They are generally quite reasonably priced and are made from durable materials that should give you several years of use.

While there are many benefits to greenhouses, it’s important to remember watering will be an issue, as the natural rains will not reach your plants, and overheating can be an issue in extreme summer heat.

 

There are three main types of greenhouses:

  • Cold frame, which are bottomless and can easily be moved. They are ideal for the early spring and late fall seasons to help protect and encourage plants to grow that would otherwise perish due to cooler temperatures.
  • Starter, which are small to medium in size and ideal for starting seedlings and hardening off plants which will be transplanted to your gardens.
  • Grower, which are the largest and can be used to start seedlings, harden off plants, grow crops to harvest, and even cure them for storage.

No matter which type you purchase you’ll want to consider if there is adequate size, ventilation, insulation, and durability for your needs. All of these variables will ultimately impact the final price of your unit.

With the above information in mind, in no particular order here are 10 of the greenhouses we consider to be best, based on available features and average customer ratings and reviews.
