In Container Gardening, Enjoy Growing Lettuce, an Anti-Alzheimer's
Lettuce (Lollo rosa variety) in hydroponics garden
Lettuce adds to your health; violet variety controls Alzheimer's disease
By Conrado D. Fontanilla
In hydroponics gardening you need a container (like styropropylene boxes), some medium to prop your plant erect (like coconut peat or sterilized garden soil), and nutrient solution that had been formulated by a research laboratory . This lab had ensured that the mix provides the necessary nutrients that are not toxic to the plant and to man.Make sure that the solution is aerated. Of course, locate your garden in a spot where there is enough sunlight. You may keep off pests with the use of screen.
I have another Hub: “How To Grow Kangkong in a Hydroponics Garden."
Ensure that the medium is not dried up. Otherwise your lettuce will also wilt. At the start fill up to half your container then add solution later.
You may choose the lettuce Lollo rosa variety (Lactuca sativa L.) for your hydroponics garden.
The Philippine Food Composition Table of the Food and Nutrition Research Institute of the Department of Science and Technology shows, based on 100 g, that lettuce leaves and petioles contain the following: water, 94.1 g; energy, 22 kcal; protein, 1.3 g; fat, 0.4 g; carbohydrate, 3.4 g; crude fiber (dietary fiber), 0.6 g; Ash, 0.8 g; calcium, 97 mg; phosphorus, 34 mg; iron, 3.4 mg; beta carotene, 1000 µg, total vitamin A (RE), 300 µg; thiamine, 0.06 mg; riboflavin, 0.4 mg; niacin, 0.5 mg; ascorbic Acid, 19 mg.
Your hydroponics lettuce enhances your health. Owing to its pigment, lollo rosa lettuce is one of the top 10 antioxidant veggies.
Alzheimer's (New entries as of June 15,2012)
Lettuce of the variety Lollo rosa, colored violet, helps in treating Alzheimer's disease or forgetfulness in old age.
It has been found that Alzheimer's is caused by a lot of aluminum fibers in brain cells. Aluminum fibers are also found in the blood of those afflicted with this disease (Cranton, E., MD. Bypassing Bypass. Updated second edition. 1995). .
Lollo rosa contains the pigment anthocyanin in its cell saps; anthocyanins are purple, red and blue pigments found in the juice of fruits and vegetables.
“Anthocyanins that have two or more adjacent unsubstituted hydroxyl groups react with iron, aluminum, or tin to form greenish, blue or slate-colored complexes. These metal chelates, the color of which depends on the metal involved and the chelation sites on the pigment, make the food unattractive….” (Paul, P,C. and H.H. Palmer. Editors. Food Theory and Applications. 1972:287, emphasis supplied).
Anthocyanins bind with and remove metals including iron. Iron facilitates the reaction between molecules of superoxide that produces hydroxyl radical. Free radicals cause cancer, heart disease and more (Cranton, E., MD. Bypassing Bypass. Updated second edition. 1995). Chelation therapy has been found to treat Alzheimer's. Consumption of fruits and vegetables containing anthocyanins is considered as oral chelation.
The combination of metal and chelator is ejected from the body. I have a Hub "Alzheimer's is caused by aluminum fibers; treated by chelation therapy and red, blue purples fruits and vegetables." End of new entries
Germination and transplanting
Seeds are sown on coconut peat or garden soil 4 inches thick, compacted a little, on a sowing tray. Water with tap water or rainwater. In seven days prick seedlings and dibble the small roots on garden soil spread on a seedling tray. Be sure that you have sterilized the soil before using it. After seven days in the pricking tray, transplant seedlings in growing boxes, almost full with the prop medium (coir dust) and half filled with the plant snap solution. Just be sure that the solution reaches the roots of the seedlings.
Formulated snap solution
Prepare growing media/solution consisting of 10 liters tap water for each planting hole or in separate containers. This volume may be poured to the planting hole all at once or staggered according to the capacity of the planting hole/container.
To each planting hole (container with 10 liters of water), add 75 milliliter (mL) of SNAP solution A and stir well. Then add 75 mL of SNAP solution B and stir well.
Maintain a 6.4 pH for the solution.
SNAP solution A: nitrogen at 0.02%; P2O5 at 0.13%; K2O at 0.04%; calcium at 0.06%; magnesium at 0.01%. These should be mixed in 1 liter tap water.
SNAP solution B: SO4 at 0.28 parts per million (ppm); iron at 63 ppm; zinc at 19 ppm; and manganese at 19 ppm. These should be mixed in 1 liter tap water.
The Institute of Plant Breeding of the College of Agriculture of the University of the Philippines Los Baños formulated this snap solution. It is suited for several veggies like kangkong.
You can also use the Murashige and Skoog (MS) solution instead of the snap solution. It appears that MS is made in the US but marketed worldwide so that you may find it in gardening stores.
In 28 days from the day of transplanting, you may harvest your hydroponics lettuce.
Relish your fresh, antioxidant and anti-Alzheimer's lettuce.
