Benefits of growing cannabis in a greenhouse

Growing weed in a greenhouse has many benefits. Let’s look at some of them:

  • Extend your growing cycle. You can extend the cultivation period into the fall and winter seasons. By adding more light on overcast days and heating for colder days.
  • A microclimate for your weed. Growing weed in a greenhouse provides the perfect microclimate for growing cannabis. A greenhouse can sustain higher average temperatures.
  • Cultivate year-round. In a greenhouse, you have complete control. The walls of the greenhouse lock humidity and heat inside: promoting year-round growth.
  • Consistent harvests. Most commercial medicinal growers use greenhouses because of their reliability in producing consistently high yields and quality marijuana.
  • Energy-efficient. Growing cannabis in a greenhouse is vastly more energy-efficient than growing indoors. That’s because a greenhouse uses natural lighting.
  • Your plants are protected. The elements won’t harm your cannabis, so you can rest easy when a storm is brewing. It also protects marijuana from pests and diseases
  • Inexpensive. Greenhouse grown weed is a cheaper form of cultivation. And it is more cost-effective to purchase/build one than to set up an indoor system.

  

Building or buying a greenhouse for weed

 

Deciding which route to go when growing in a greenhouse is essential. You can build or buy one. Buying one is convenient. It comes as a kit that you assemble yourself; however, even though it’s convenient, it’s more costly up-front.

Building a greenhouse takes skill and time. Choose suitable materials and learn how to assemble one. A little mistake like not sealing it properly can have dire consequences, like your plants freezing in winter.

 

The benefits of building a weed greenhouse

 

Building a weed greenhouse offers the benefit of being cheaper. This option requires a few key components:



  • Choose the right location. Environmental and geographical factors play a role when building a greenhouse. For example, the materials used for one in Colorado may not be suitable in another location.
  • Temperature control. Greenhouse heating and cooling systems must meet the needs and controls of each grow zone. On average, the temperature should be between 65–85° Fahrenheit.
  • Control humidity. Design your greenhouse in a way that you can monitor air moisture levels. Dehumidifiers are an option, and you can use misting systems to create more humidity.
  • Install proper ventilation. Adding vents on the roof, sidewalls, or installing rollup sides will work perfectly. You need a system that removes hot air from the greenhouse. Many growers like to use airflow fans.
  • Install blackout curtains for the flowering stage. Make sure to cover the greenhouse well, including the entrance and vents.
  • Make provisions to incorporate carbon dioxide into your greenhouse. Cannabis grown in a greenhouse thrive on CO2. Use liquid CO2 to boost plant growth.
