Celery is a vegetable that can be produced well in a hydroponic environment. Hydroponic system growth removes several problems that can plague conventional garden plants, including insects and other pests, weeds, and soil toxins.
Celery is loaded with antioxidants. These include well-known varieties such as flavonoids and vitamin C, as well as lunularin and bergapten. These and other antioxidants help to prevent the oxidative stress that contributes to cancer. Celery is rich in a phytochemical known as phthalides.
For the best results, keep celery heads whole, wrap them up tightly in aluminum foil, and then keep them in the refrigerator crisper drawer as usual.
