Growing Hydroponic Romaine Lettuce

Romaine or cos lettuce (Lactuca sativa L. var. longifolia) is a variety of lettuce which grows in a tall head of sturdy leaves with a firm rib down the center. Unlike most lettuces, it is tolerant of heat.

My cultivar is Parris Island Cos Lettuce

This popular Romaine has upright growth to 10 inches with large thick medium green slightly rumpled leaves with creamy white centers. Tender, crisp and sweet flavored. It is tolerant to many lettuce diseases and is slow bolting. Approximately 65 days to maturity.

Hydroponic Lettuce, Bangalore

This the First Hydroponic commercial pilot project in India as per my knowledge

Hydroponics ( Name comes from the Greek words hydro, water and ponos, labor) is a method of growing plants soi . Terrestrial plants may be grown with their in the mineral nutrient solution only or in an inert medium, such as gravel, mineral wool, or coconut husk.

I have selected to grow hydroponic lettuce in Nimai Garden, Electronic city,Bangalore ,India

The Four common lettuces are

1)  Leaf Lettuce

The leaf lettuce comes in many colors, from emerald green to dark maroon. Textures range from rounded edges to frills and ruffles.

2) Romaine lettuce

This lettuce is pack with nutrients. The romaine lettuce is high in vitamin A, vitamin C, and beta-carotene which make it a heart-healthy green. The vitamins, minerals, nutrients, and fiber found in romaine lettuce are good for many common health problems.

3) Butter-head lettuce

This lettuce is a good source of vitamins, magnesium, calcium, potassium, and iron, mostly used in salads

4) Crisp-head or green ice lettuce

The iceberg head lettuce is the most common lettuce in India . 

 

My cultivar 

Batavia Lettuce is classed variously as a loose-leaf lettuce, or semi-heading lettuce.

I have used  float bed bed or water culture to grow hydroponic lettuce
