China Floating Hydroponics Suppliers - DFT System from Trusted Factory for Efficient Vegetable Cultivation

The Deep Flow Technique (DFT) is an innovative hydroponic gardening method designed for efficient plant growth. In this system, plants are situated in shallow beds, with a continuous flow of nutrient solution circulating around their root zones. This approach is particularly advantageous for plants with shallow root systems and those that exhibit rapid growth cycles. By allowing the nutrient solution to occasionally flow away from the roots, the DFT is well-suited for plants that thrive with brief drying periods between waterings.

,

Commonly utilized in aquatic crop production, this technique ensures that plants like watercress, rice, and water chestnut receive essential nutrients in wet and warm environments. Additionally, DFT is a preferred solution in regions where cultivating fresh, leafy vegetables is challenging.

,

Floating hydroponics, a variant of DFT, is currently employed for vegetable cultivation. This system includes a nutrient solution tank, planting plates, a nutrient solution pool, and a nutrient circulation system, typically constructed from high-quality plastic or hot galvanized plates. As leading suppliers and a reputable factory in China, we provide advanced hydroponic solutions to enhance your gardening experience.

    Frequently Asked Questions

    Q1: How does responsive web design affect Google SEO rankings?

    Google uses mobile-first indexing, meaning it predominantly uses the mobile version of the content for indexing and ranking. A responsive design ensures your site performs well on mobile devices, directly boosting your SEO visibility.

    Q2: What is the recommended maximum width for images on web pages?

    For standard content areas and grid layouts, restricting image widths to 500px or using responsive percentage widths ensures fast loading speeds while preventing layout shifts on mobile devices.

    Q3: Why is clean HTML structure important for search engine crawlers?

    Search engine crawlers rely on semantic HTML (like properly structured heading tags and clean CSS classes) to understand the context and priority of your content, leading to more accurate indexing.

    Q4: Do visual elements like images and videos improve user engagement?

    Yes, well-optimized visual elements increase the time users spend on your site (dwell time) and reduce bounce rates, both of which are positive signals for search engine algorithms.

    Q5: How do you prevent custom CSS from conflicting with existing website styles?

    By utilizing a unique naming convention prefix (such as using specific class identifiers) for all selectors, custom styles remain isolated and will not interfere with the host website's global styles.

    Greenhouse Cover&Structure

    • 1. Steel Structure
    • Steel structure material is high quality carbon steel which is accordance with national standard. Steel parts and fasteners are processed according to “GB/T1912-2002 Technical Requirements and Test Methods of Hot-galvanized Layer for Metal Coating Steel Production”. Inside and outside hot galvanized steel should meet the national standard (GB/T3091-93) requirements of quality products. Galvanized layer should have thickness uniformity, no burr, and the galvanized layer thickness is not less than 60um.
    • 2. Cover material
    • A. Intensity improved: toughened glass, mechanical strength, impact resistance and bending strength can reach four to five times of common glass.
    • B. Heat stability improved: tempered glass can withstand the large temperature difference, not damaged.
    • C. Security improved: after high strength damage, toughened glass turn into tiny particles, maximizing the personal safety.

    Outer Sunshade System

    In the summer when indoor temperature rise to a certain value, it can reflect a part of the sun and diffuse sunshine into the greenhouse according to the different shading rate, achieving the purpose of cooling temperature. Close sunshade screen, at the same time the greenhouse temperature drop 4 ~ 6℃, reduce temperature in the greenhouse. By choosing different shading rate curtain, it can meet the sunshine demand of different crops.

    Inner Sunshade&Warming System

    p2gfc

    This system is installing inner sunshade net in the greenhouse.In summer, it can reduce the inner temperature, and in winter and in night, it can prevent the heat running off. It has two types, ventilation type and thermal insulation type.

    Cooling System

    Cooling system can decrease the temperature according to the principle of evaporation of water for cooling. System has high-quality cooling pads and the fans with big wind.The core of cooling system is the cooling pads, which can evaporate water, is made of corrugated fiber paper.it is corrosion resistant and has long working life, because the raw material is added to a special chemical composition. The special  cooling pads can ensure the water wets whole wall of  cooling pads. When the air goes through the pads, the exchange of water and air on the surface of pads can change the hot air into cool air, then it can humidify and cool the air.

    Ventilation System

    p4e71

    Greenhouse ventilation system is divided into two kinds, natural and forced ventilation. Glass greenhouse natural ventilation is opening staggered windows on the roof. Forced ventilation is achieved through installing blowers. In general, we install the cooling system of fans and cooling pad. Ventilation systems can be customized according to customer needs and planting conditions.

    Heating System

    Heating system has two types, one type is using the boiler to provide heat, and another uses of electric. Boiler fuel can choose coal, oil, gas and bio fuels. Boilers need laying of pipelines and water warming blower to heat. If use electricity, you need electric warm air blower to heat.

    Light Compensating System

    p61bb

    Greenhouse compensating light, also called plants light, is a required light of supplying light to the plants for growing and developing, instead of sunlight according to the natural law of plant growth and the principle of plants using sunlight for photosynthesis. At this moment most of farmers use high pressure sodium lamp and LED lamp.

    Irrigation System

    We supply two types of irrigation system, drip irrigation system and spray irrigation system. So you can choose the best one for your greenhouse.
