The Nutritional Value of Lettuces
Of course, the vitamin content of lettuce depends on how it's grown. Lettuce that has it's leaves spread during growth, as opposed to those which grow with tight heads, have more vitamins that are sunlight dependant.
Hydroponic lettuces that are grown with maxed out nutrients and organically grown lettuces that are grown in maxed out organic soil are WAY above the rest when vitamins are in question.
With hydroponic veggies, the ratio is about 10 times of what is in commonly grown soil veggies.
