What Is a Grow House?

Grow houses are types of greenhouse buildings specifically dedicated to growing cannabis. Growers typically outfit these structures with hydroponic equipment that provides light, water, and nutrients to the marijuana plants. An ideal weed grow house should be able to withstand consistently humid environments and maintain warm temperatures between 75 and 85 degrees. Hansen Pole Buildings can help you create commercial grow room design plans that will meet these conditions.

How Much Does It Cost to Build a Weed Grow House?

The overall cost of your marijuana grow house pole building kit will depend on its size and your customizations, as well as local design requirements and material costs. You could pay anywhere from $7,000 to $100,000.

Affordability is one of the main reasons to go with a pole building over other means of construction. The cost to build pole barn grow houses is often substantially lower than other construction methods because they require less material to construct—even added features typically cost less in a pole barn than in a traditional building.
