Thought some of you might find this interesting. Link leads to the full study. Comparison of the Cannabinoid and Terpene Profiles in Commercial Cannabis from Natural and Artificial Cultivation. (USA) (full – 2023) Comparison of the Cannabinoid and Terpene Profiles in Commercial Cannabis from Natural and Artificial Cultivation Interest in cultivating cannabis for medical and recreational purposes is increasing due to a dramatic shift in cannabis legislation worldwide. Therefore, a comprehensive understanding of the composition of secondary metabolites, cannabinoids, and terpenes grown in different environmental conditions is of primary importance for the medical and recreational use of cannabis. We compared the terpene and cannabinoid profiles using gas/liquid chromatography and mass spectrometry for commercial cannabis from genetically identical plants grown indoors using artificial light and artificially grown media or outdoors grown in living soil and natural sunlight. By analyzing the cannabinoids, we found significant variations in the metabolomic profile of cannabis for the different environments. Overall, for both cultivars, there were significantly greater oxidized and degraded cannabinoids in the indoor-grown samples. Moreover, the outdoor-grown samples had significantly more unusual cannabinoids, such as C4- and C6-THCA. There were also significant differences in the terpene profiles between indoor- and outdoor-grown cannabis. The outdoor samples had a greater preponderance of sesquiterpenes including β-caryophyllene, α-humulene, α-bergamotene, α-guaiene, and germacrene B relative to the indoor samples. Granny
Nothing empirical testing hasn't told me for 40 years and more. Outdoor grows under the sun still can't be beat by the best that indoor can do. Something about that big old glowing Orb in the sky. Soil full of Microbes and Fungi. Now if I can just teach the Praying Mantis to eat more Moths and Caterpillars. I wonder if Google translate does Manti speak? Love ya Granny. Keep up the great work.

My outdoor was awesome!! That is, until it frosted late last spring. ( no problem , Agribon to the rescue). Then came the grasshopper infestation. Plague like… ground was crawling with them. ( no problem, Agribon to the rescue… again). What’s next? Oh yeah… unseasonably high winds. 60- 80mph gusts. ( no problem, bombproof hoopers and … Agribon to the rescue.) Sweet! I’m almost there! Wait. What are those? APHIDS…?! Are you f’ing kidding me? Total infestation that organic IPM would get laughed at. Literally had to spray them of the colas twice a week. It took four days to harvest it all, cleaning and washing each branch by hand. Turned half of the entire run to concentrates , and discounted the rest. Maybe MT doesn’t have the best outdoor growing conditions. My finest quality flower by far comes out of my rooms. Without the insect problems, that outdoor could have been great though.
I think it's an interesting study. But, it seems to be comparing apples to oranges. Why not use living organic soil indoors as they were doing outdoors. This is the medium they used for the study for their indoor grown plants,artificial growth media. So I don't find this a very fair comparison. I think this just reinforces organically grown weed is superior to salt based grown weed. But, I think we can all agree we already knew this.
@TimJ They have to start somewhere! And if you click "Author information", you'll find an email address for you to correspond with the authors! Why not suggest that their next study should have a wider range of growing mediums in both indoor and outdoor? A while back, I commented on a study once (it was on nutrition in cattle and fertility). I made a few polite comments and observations on how the dietary change affected the endocannabinoid system. I got invited to join in their group's next study! (and I likely got on some US government list for that) I politely declined since the study was out of Iran, and I wasn't sure how they would react to a rather liberal, pot-smoking, feminist, old hippie gal like me!

First, let me say. I always enjoy reading your posts. I wouldn't join a study either. For the fear of being on a list of sorts as you mentioned. I think it would have been more interesting to learn what variable actually had affected these changes. Was it the light source or the growing medium/nutrients. Personally, I believe it is the latter.
