10 Highest Yielding Indoor Strains – Compact Grows + Potency

When it comes to smoking cannabis flower, taste, aroma, and potency are at the top of most people’s lists, as far as important traits are concerned. When it comes to growing cannabis flower (especially on a large scale), all of those things are still important, but choosing a plant with a high yield will make your operation more efficient… and who doesn’t want to save some green while growing it?

10 Highest Yielding Indoor Strains

Yield, by agricultural definition, is “the amount of crop harvested per area of land.” It is used to describe the output for many crops, including corn and most grains, and the majority of the cannabis industry also measures their ergonomic output by yield. Marijuana growers in the U.S. haven’t mutually agreed upon which “area of land” to use as reference in their yield equations yet, but some common ones are gram-per-square-foot, or ounce-per-square-yard. For this article, we will be using the latter as our reference (e.g., 24 oz/yd2).

In this article, we will be describing ten of the highest yielding indoor strains you can grow. If you’re looking strictly for the highest yielding autoflower strains then check out our guide!

What You’ll Need to Know Before Growing Indoors:

Another measurement comes into play when growing indoors, and that is electric bills. Make sure to use efficient lighting, and ensure your grow room is light-tight. This will not only keep the bills low, but changes in light can cause some plants to produce male flowers (the ones that don’t get you high). 

Light-tight doesn’t mean air-tight, however, and your plants will need to get fresh air to reach their maximum yield potential. Temperature control is also a make-or-break factor, so ensure you’re able to keep your grow room at comfortable temperatures (~ 60-85OF depending on lighting and strain) throughout the entirety of the grow period. 

With those steps in order, and the time needed to give the plants proper watering and nutrients, you’ll be ready to go, and poised to maximize the yield of your indoor marijuana grow.  Take a look below for our highest yielding strains indoors.

The color changes during the budding process are quite a sight, as well. These can still definitely be grown indoors if you have space/organization for it.
