Medium Size Greenhouse Kits

Medium size greenhouses are generally preferred by hobbyist growers that also want to grow some of their supplies for commercial uses. ShopGrowSpaces has gone to great lengths to ensure our customers have access to the quality range of greenhouse supplies.

Its very important to determine whether a greenhouse is small, medium or large quantitatively. Considering that every greenhouse has different widths and lengths, we, at ShopGrowSpaces, decided to use square feet as a measurement. Determining whether a greenhouse is small, medium or large is a subjective decision. 

How big is a medium size greenhouse ?

At ShopGrowSpaces we categorize all greenhouses with size 65-150 square feet under our medium size greenhouse collection. These handpicked greenhouses usually have access to all of the accessories for serious gardeners, who want to grow plenty veggies or fruits, as well as greenhouses for commercial and educational use.

How big of a medium size greenhouse do I need?

We always give customers the tip to buy one size larger than you planned. Remember that your plants will grow. That compact space you used to start the seeds will triple when plants are potted up. So be smart and think about the plants you want to plant before purchasing. However, we do understand that you might be a little hesitant to purchase a bigger greenhouse intially, so you will find that some of our greenhouses are extendable, so you will find you can also start with a small size and upgrade later on.

The cost of each medium greenhouse kit varies depending on materials, the size and color of the materials used to construct it (which can vary from $3000 - $11,000).
