Because they aren’t specifically testing outdoors va indoors in the exact same conditions, but testing outdoor vs indoor in their typical conditions.

Except you then don’t know if it was actually outdoors that led to this or say the nutrient mix lacking some ingredient in the indoor mix.

It’s useless data.

Well, no studies are perfect, but if thats the soil they are grown when sold, it makes sense to compare them that way, and is definitely useful data.

Then those differences should be explicitly pointed out in the materials and methods as well as how they affect the results in the discussion.

There are a lot of proprietary soil mixes and nutrient/fertilizer regimes. Without this knowledge it is impossible for other groups to repeat this work. As such, the data has some use but is lacking enough detail to be less than definite.
