I like this idea, it may be the only real way to tell. Possible to only do two groups? Maybe just two outside, one under the sun, one in a tent with same weather conditions, only under "artificial sun". It's true with the strains though, there are so many crosses now and phenotypes that are designed to grow indoors and what not, and some that are best outdoors.
