Why are hydroponic lettuces safer?

If you ever wonder what the difference is between hydroponic lettuces and regular ones when you go to the supermarket, here you will finally find the answer to that great question.The main difference with hydroponic lettuces is the way they are produced: while they grow in a greenhouse and within a liquid nutrient solution, the others are traditionally harvested from the soil, are in contact with livestock and other animals, and are watered using various irrigation methods.And it is precisely this significant difference that makes hydroponic lettuces safer, as many times, the irrigation water for the others can be contaminated with bacteria like E. coli. Additionally, they offer many benefits, for example, their production is more sustainable and they are just as nutritious as the others.
