What are indoor strains?

Indoor cannabis strains are specifically cultivated to be grown inside with assistance such as artificial light. They generally struggle to adapt to harsh, unpredictable outdoor climates and need a more controlled environment to flourish.

Most indoor strains are, in fact, able to be grown outdoors but need the right conditions. A variant that can’t develop in a cold climate may do better in a warmer place. For the purpose of this article, the best indoor strains referred to are ones that grow better overall and produce higher yields in an enclosed environment. 

What are the benefits of growing marijuana indoors?

What’s the hype about growing your cannabis in an enclosed environment? Is it worth the extra costs incurred? Let’s take a look at some of the benefits of indoor vs. outdoor cultivating. 

Indoor growing:

  • Control. Growers can maintain continuous light cycles, temperatures, CO2 levels, humidity, and pest control.
  • Delicate strains that don’t do well outdoors can be cultivated.
  • Consistency. Each strain requires specific conditions to thrive. These can be tested and replicated to ensure maximum yields.
  • Outdoor growing can cause stress for flora. Natural disasters, heavy winds, and sudden heavy downpours all take their toll on your plants.

Outdoor growing:

  • Natural predators. Unwanted pest populations are controlled by their natural enemies.
  • Sunlight. Nothing quite beats the energy that sunlight provides plants. No amount of artificial light can have the same effect as the sun.
  • Sustainability. A lower cost is incurred when growing outside. You’ll produce a smaller carbon footprint using natural elements to grow your crop.

What are the best indoor strains?

Each grower has their preference when it comes to the effects, potency, flavors, and aromas they’d like to produce. We’ll take a look at the top ten best indoor strains in detail to ensure that you make the best decision for your harvesting journey.
