Many popular tourist locations are in areas of limited agricultural production. As a result, all food must be shipped into the countries by air or sea.
In this topic, we discussed about the basic parts of Hydroponics, what is a Hydroponic system, recovery system, how to tomatoes grow in a hydroponic system. We also differentiate the two main category of Hydroponic system: Active or Passive.
I seem to be always in the process of growing either hydroponic lettuce using the Kratky Method.

Tomatoes are one of the most popular crops grown hydroponically. Growing them yourself will give you great pleasure in producing tomatoes with that rare “backyard” flavor that cannot be obtained from those you buy at supermarkets.
Lettuce (Lactuca sativa) is the fourth most important vegetable crop grown hydroponically in greenhouses proceeded by tomatoes, European cucumbers and peppers. Although greenhouse production of lettuce is very small in comparison to field grown, it has a specific market niche as a gourmet, high-quality item.
Please refer to the previous article “Hydroponic Culture of Lettuce I” for details on varieties, starting the plants, nutrient formulation and nutritional & environmental disorders, pests and diseases.
The previous article “Hydroponic Culture of Lettuce II” described the narrow channel NFT system for growing lettuce. This article describes the raft or floating system, which is especially suited for warmer climates.
The most popular cucumbers grown hydroponically in greenhouses are the “European” or “Long English” cucumbers (Photo 1).
