Smokable Flower Growing Methods: Indoor, Greenhouse, and Outdoor

There are three main methods of growing hemp: indoor, sun-grown with light deprivation (greenhouse), and full term sun-grown (outdoor). Each has its advantages and disadvantages, which will lead to your preference in smokable hemp flower.


Growing hemp indoors gives growers complete control of the entire production process, including room temperature and air circulation.  This would seem to be an advantage as you can have complete control of every element.  However, the concern of having no natural elements in the manufactured environment can lead some to believe that this can have impacts on the quality of the terpenes in the flower harvested from the plant.


The second major method of growing hemp flower is sun-grown with light deprivation, otherwise known as greenhouse. Light deprivation allows us to block out the sun with tarps, tricking plants into flowering faster, enabling us to control the natural environment by simulating seasons from spring to summer to fall based on the number of hours of light.

Growing with natural sunlight supports a full and natural terpene profile. Even if plants grow big and full under artificial lighting, the results will still be different from plants grown under true sunlight.

The greenhouse method also has less of an impact on earth’s natural resources. Sun grown hemp flower takes a lot less energy than all of those lights and fans used to power indoor growing, promoting sustainability by leaving a lot smaller of an ecological footprint.

Jeremy Moberg, CEO of Washington’s CannaSol, says that light deprivation produces the highest quality product with the least impact on the environment.

In Georgia, the climate is mild enough to grow hemp year-round with its ample sun and excellent temperatures.  For greenhouse growing, there is very little supplemental ambient modification that is required aside from air flow.


Full-term outdoor growing is the most natural and least expensive way to grow hemp. It takes no lights and no fans and no tarps, and only uses tents, sunlight, and soil. The obvious disadvantage of this method is that plants are exposed to the elements (environment, temperature, pests, etc.), which could have a detrimental effect on the quality of the flower.

Which Should You Buy?

I have my own personal preference (hence the greenhouses!).  Scientifically there’s no “best” way to grow hemp, it all comes to down your personal preference and sought after experience.

Another question is why consumers would choose greenhouse or indoor-grown hemp over the alternative of outdoor hemp.  Aside from the ability to control the environment, outdoor hemp is subject to all of nature’s and man’s elements – such as pest, mold, pesticide spray drift, and many other influences.  Think of all the cattle farms, chicken farms, pastures, automobiles and forest fires that affect our everyday outdoor growing.  These environmental factors remain on the plant and affect the health and quality of the resulting flower.

Unlike fruit, which you can clean with water, anything sprayed on hemp during flowering gets stuck to the trichomes.  For consumers who choose experience over everything, sun-grown hemp with light deprivation may be the choice for you.  The sun has different spectrums that indoor can’t really duplicate. If done the right way, it can feed the different terpenes or cannabinoids that enhance plants a little bit more.

With a greater understanding that effects are most likely derived from terpene and cannabinoid profiles, smokable consumers are turning to sun-grown hemp.

No matter whether it is called light-dep, sun-grown or greenhouse, it is quickly becoming the educated consumers’ preference as they learn that this method produces greater amounts of terpenes and cannabinoids.  Light-dep, combined with living soils is, in my opinion, the best.
