Growing Indoors vs Growing Outdoors

Growing outdoors is the traditional and old-school way of growing your weed under the natural light of the sun and the breeze that naturally exists in the environment. Growing outdoors also means you don’t really have to take too much care of the plants as they largely grow on their own, as they would in nature. This is an inexpensive process meant for casual growers. However, growing in an outdoor grow tent is something different!

Growing indoors is something which is for serious growers – as it involves ensuring that you are creating the best possible scenario for the growth of your plant. Growing indoors means you are growing using grow tents fitted with grow lights, providing the best nutrients and using equipment like dehumidifiers and air conditioners and carbon filters to give the plants a major boost in their growth process. 

Why Grow in an Outdoor Grow Tent?

Growing in an outdoor grow tent is basically like growing in a greenhouse. This is a fair mix between indoor and outdoor growth. Growers can set up all their equipment inside the grow tents but a lot of the features of outdoors settings such as natural lighting and ventilation are retained. This keeps the pests and insects away while giving the plants access to sunlight and breeze – an ideal combination for a healthy growth of the marijuana plant.

Benefits of Growing Marijuana Inside an Outdoor Grow Tent

  • Access to natural sunlight is one major benefit of growing your plants in an outdoor grow tent. The best outdoor grow tents feature transparent surfaces that cover the body which allow the sunlight to enter while also storing warmth and humidity which is great for the growth of the plants. You also get access to natural lighting and don’t need to set up grow tents.
  • Breeze is good for the growth of the plants and most of these outdoor grow tents have enough space and ventilation which allow for a smooth airflow. A decent breeze around the plants ensures that the stem as well as the branches of the plant grow stronger and that insects are kept away.
  • A fair mix between indoors and outdoors growth as you can get all the natural elements plus also keep in certain electronic elements which give you a greater control over the growth of your plants! It is basically the best of both worlds.
  • Saves money on electricity as you do not need to set up a grow light or other equipment which you would normally need to do to replicate the outdoor environment indoors.
  • Keeps pests away as it is covered by a layer all around it
