1. Crops can be produced on non-arable land (not fit for farming). Ex. Land with poor soils, and contamination (i.e., high heavy metal and salinity levels). *The grower doesn’t have to have good soil since the systems, bags, etc. are placed on top of the ground. 2. Isolation from diseases or insect pests usually found in the soil. *The plant roots are contained in systems, bags, etc. and do not grow through soil that might contain diseases or other pests such as insects and nematodes. *Additionally, white fabric ground covers can be placed on the greenhouse floor to further isolate the systems and plants from soil-borne pests. NOTE: The white fabric also reflects light back up into the canopy enhancing photosynthesis, allows for ease of cleaning and helps control humidity and weeds. 3. Direct and immediate control over the rhizosphere. *Since the roots are either growing in water or growing through an inert medium, whatever is in the nutrient solution is bathing the roots. Therefore, nutrient concentrations and pH can be adjusted quickly. 4. High planting densities are possible which minimizes use of land area. *For field tomatoes a typical planting density is 4000 to 5000 plants per acre. Greenhouse hydroponic tomatoes can be 10,000 to 11,000 plants per acre! *Plants can be grown closer together because of the use of indeterminant (“vining”) varieties that take up less area than do bush varieties usually used for field cropping. Also they need less root room – the plants are “spoon fed” the nutrient and water they need and do not have to grow a large root system to find these, as field tomatoes do in the soil. 5. Higher yields are ...
Like much of agriculture, Alabama’s aquacultural production sector has been under stress for several years. Alabama producers and intermediaries in the system face competition from others in the ﬁsh and seafood industry, both domestically and internationally, as well as from producers and handlers of other protein sources. Prices for farm level products have generally been depressed and input costs have been on the rise. Thus, proﬁt margins have become thin to nonexistent. Resource owners are interested in identifying and evaluating viable alternative uses for their productive assets. To cope in this environment and be proﬁtable, Alabama aquacultural producers must organize and operate to maximize efﬁciency and be innovative in decisions and actions. Existing ﬁsh production technologies and approaches, primarily pond culture, may not compete effectively. Increasing yield per unit of water, lowering cost per unit of product, and/or enhancing market access could improve the plight of producers. This study aims to identify and assess the technical and economic feasibility of an alternative production system that integrates hydroponic tomato production with production of channel catﬁsh or tilapia using recirculating water through a closed, controlled environment using separate greenhouses to produce tomatoes and ﬁsh throughout the year.

Greenhouse tomato production has attracted a great deal of attention in recent years. However, of all the greenhouse crops, tomatoes (Lycopersicon esculentum) are the most complicated to grow because they require the most management, the most labor, and the most light. A grower must be committed to meeting the daily demands of production in order to be successful. Prospective growers need to get as much information as they can about all aspects of greenhouse production before beginning this enterprise. Marketing The development of farmers markets, roadside farm markets, and produce auctions across the state offer significant opportunities to sell produce from the farm. Tomatoes can be sold directly from the greenhouse at retail prices. Wholesale markets include supermarkets, restaurants, caterers, and wholesale distributors. Market Outlook The U.S. greenhouse tomato market is increasing dramatically as many consumers will now pay an increased price for a red, ripe tomato. It is possible for Kentucky growers to sell greenhouse tomatoes in this expanding market. Early-season tomato production may also capture higher prices resulting in profitability from intensive production systems. Excellent light, moderate heating costs, high yields, and good prices make spring the best time for greenhouse tomato production in Kentucky. On the other hand, fall and winter production generally results in low returns due to reduced yields and high fuel costs. For this reason, it is difficult to recommend production schedules where tomato harvest would be expected from December through mid February. Production Considerations Production systems There is no single best system for successfully growing greenhouse tomatoes. Many production systems will work if the grower correctly manages fertilization and watering. With experience, individual growers will be able to determine the best and most economic techniques to use in their greenhouse. A number of different types of growing media can be used for greenhouse tomatoes, including good field soil, packaged commercial mixes, and various types of hydroponic media. Use only materials that have been sterilized, pasteurized, or manufactured under clean, disease-free conditions. Small growers often use in-ground soil culture in the beginning, but generally switch to perlite or pinebark culture as they learn more about tomato production. A drip irrigation system is used for the distribution of water and nutrients. Tomatoes require 4 square feet of space per plant. This crop will require attention everyday to ensure success. Equipment (such as fans, vents,...
Nutrient Solution Formulation for Hydroponic (Perlite, Rockwool, NFT) Tomatoes in Florida1 George J. Hochmuth and Robert C. Hochmuth2 Plants require 16 elements for growth and these nutrients can be supplied from air, water, and fertilizers. The 16 elements are carbon (C), hydrogen (H), oxygen (O), phosphorus (P), potassium (K), nitrogen (N), sulfur (S), calcium (Ca), iron (Fe), magnesium (Mg), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), and chlorine (Cl). The key to successful management of a fertilizer program is to ensure adequate concentrations of all nutrients throughout the life cycle of the crop. Inadequate or excessive amounts of any nutrient result in poor crop performance. Excessive amounts can be especially troublesome since they can damage the crop, waste money and fertilizer resources, and pollute the environment when fertilizer is released during flushing of the nutrient delivery system. problem comes early in the season when plants become too vegetative (bullish) from too much N. The bullish growth distorts the leaves and stems, causing cracks and grooves in the stems. These openings are excellent entry ports for decay-causing organisms such as soft rot. Bullish plants usually produce misshapen fruits often with significant amounts of blossom-end rot and cat-facing. Keeping the N level low (60 to 70 parts per million) early in the season helps eliminate bullishness. For Florida greenhouse vegetable producers, management focuses on all nutrients except for C, H, and O. The latter three elements are usually supplied in adequate amounts from air and water. Growers in northern climates, where greenhouses are not ventilated in the winter, see benefits from additions of C from carbon dioxide (CO2). Increased yields in Florida from additions of CO2 are unlikely due to the need for frequent ventilation. Nutrient management programs should begin with an understanding of the nutrient solution concentrations in parts per million (ppm) for the various nutrients required by tomato plants. By managing the concentrations of individual nutrients, growers can control the growth and yield of the crop. Table 1 presents the fertilizer recommendations for tomatoes for the various growth stages during the season in Florida. These recommendations are applicable to all types of production systems (perlite, rockwool, and NFT) in which healthy roots are maintained, and are a suitable base when determining a nutrient solution plan for cucumbers and peppers. However, cucumbers will need more N early in the season than tomato.
