11 of the Best Strains to Grow Indoors

Best Strains to Grow Indoors

Some cannabis strains are genetically better suited to be grown indoors, and some do better outdoors. In this post, we’ll tell you about the best strains to grow indoors.

Humans have been cultivating cannabis for thousands of years. Although the tools and techniques for growing may have changed over time, the goal of every grower remains the same – to farm healthy, vibrant plants and get the highest yield possible from each plant.

In ancient times, cannabis was primarily grown outdoors. However, today, a lot of growers prefer to farm their plants indoors. Growing indoors takes up less space. Also, it gives you full control over the environment, ensuring you provide the perfect conditions for your plants to reach their highest potential.

You can control the temperature, CO2 levels, humidity, and light source when growing indoors. Cannabis plants that are grown indoors usually have a higher level of tetrahydrocannabinol (THC).

Although no indoor grow light can ever replace the sunlight, growing outdoor leaves your plant exposed to the vicissitudes of nature. Ultimately, there are pros and cons of choosing to grow indoors or outdoors. If you’re thinking of growing indoors, here are some of the best indoor cannabis strains to choose from.
