Any scientific studies on nutrient density of veg under lights?
I just finished testing (w/ 2 diff refractometers) produce from 24 sources - 18 conventional (grocery stores, farmers markets, etc) and 6 local gardeners (from people I actually know, including my parents' garden)... a total of 172 items. Sadly (and surprisingly), 4 Whole Foods and 2 Trader Joe's produce all came up being of POOR quality. Basically, (my generalization) Whole Foods sells grossly overpriced, nutrient deficient, sorry excuse for vegetables (yes... I'm bitter now :). So now I don't trust any of them and I've decided to grow my own. (btw... "Local" produce was 3 average, 2 good and 1 excellent. The ol' timers with "good / excellent", however, have completely dismissed the growing-quality-under-lights as an impossibility)
Have there been any studies comparing nutrient density of veggies grown indoors, under-lights vs veggies grown under the sun? (I'm talking about real food grown indoors, not cyborg, test-tube hydroponics pvc food). My interest is in growing strictly clean, nutrient-dense, high brix scale food. Thank you for your input.
