What is Hydroponic Greenhouse Gardening?

Hydroponic gardening is a method of growing plants without soil, using mineral nutrient solutions in a water solvent. This technique enables the growth of plants in controlled environments, maintaining a precise balance of nutrients, water, and oxygen.

Here’s how hydroponic gardening works in more detail:

If you’re more into video explainers then here is a great video for you to watch to understand how it all works.

If not – there is more information below.

Nutrient Solution:

The foundation of hydroponic gardening is the nutrient solution, which consists of water mixed with all the necessary minerals and nutrients plants normally obtain from the soil. This includes elements such as nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements like iron, manganese, boron, zinc, and copper.

Root Support:

Even though no soil is used, plants still need physical support to hold them in place. Hydroponic systems use various inert media for this purpose, such as rockwool, clay pellets, perlite, vermiculite, or even air (in aeroponic systems). These media provide support to the plant’s roots while allowing the nutrient solution to be delivered efficiently.

Water and Nutrient Delivery:

The method of delivering the nutrient solution to the plants varies across different hydroponic systems. Some common systems include:

  • Wick System: The simplest form of hydroponics where a wick draws the nutrient solution from a reservoir into the growing medium.
  • Deep Water Culture (DWC): Plants are suspended in a solution of nutrient-rich, oxygenated water. Air pumps are often used to oxygenate the water to prevent the roots from drowning.
  • Nutrient Film Technique (NFT): A thin film of nutrient solution flows over the roots of plants placed in a sloping channel, allowing the upper part of the roots to remain exposed to air.
  • Ebb and Flow (Flood and Drain): The growing area is periodically flooded with nutrient solution, which then drains back into the reservoir. This action ensures that the roots receive nutrients and oxygen.
  • Aeroponics: The roots hang in the air and are misted with nutrient solution at regular intervals. This method maximizes oxygen exposure and nutrient delivery.

Since many hydroponic systems are used indoors, providing adequate light is essential for photosynthesis. This is often achieved through the use of grow lights, which may be LED, fluorescent, or other types of lighting that provide the correct spectrum of light for plant growth.

Climate Control:

Controlling the environment includes monitoring and adjusting temperature, humidity, and sometimes carbon dioxide levels to optimize plant growth. You can set up hydroponic gardens in greenhouses, indoors with controlled lighting, or even outdoors if the environmental conditions are suitable.

What Are The Advantages Of A Hydroponic Greenhouse?

Using hydroponics in a greenhouse offers several benefits, making it an increasingly popular method for growing plants. These benefits include:

Water Efficiency:Hydroponics systems use significantly less water than traditional soil-based agriculture, as water in these systems is recirculated and reused, minimizing wastage.
Control Over NutrientsIn hydroponics, nutrients are dissolved in water and fed directly to the plants’ roots. This gives growers precise control over the nutrient balance, allowing for the optimization of plant growth and health.
Faster Growth Rates:Plants grown in hydroponic systems often grow faster and produce higher yields than their soil-grown counterparts, due to the direct supply of nutrients and optimal growing conditions.
Space Efficiency:Hydroponics can be more space-efficient than soil-based growing, allowing for higher plant density. This is especially beneficial in greenhouses, where space might be limited.
No Soil Required:This is particularly advantageous in areas where fertile land is scarce or in urban environments where soil-based agriculture is not feasible.

What Are The Disadvantages Of A Hydroponic Greenhouse?

While hydroponics in a greenhouse offers numerous advantages, there are also several disadvantages and challenges to consider:

High Initial Investment:Setting up a hydroponic system within a greenhouse can be expensive. The cost includes not only the greenhouse structure but also the hydroponic equipment such as pumps, growing mediums, nutrient solutions, and lighting systems.
Technical Knowledge and Management:Successful hydroponic gardening requires a good understanding of plant nutrition, system design, and environmental control. It can be complex to manage the nutrient solutions, pH levels, and the overall system’s health, requiring constant monitoring and adjustments.
Energy Dependency:Hydroponic systems, especially in greenhouses, often rely heavily on artificial lighting and temperature control systems. This can lead to significant energy consumption, increasing operational costs and environmental impact.
System Failures and Vulnerabilities:Hydroponic systems depend on electricity and mechanical parts to circulate water and nutrients. Failures in these systems, such as pump breakdowns or power outages, can quickly lead to plant stress or death, given the roots’ reliance on the system for water and nutrients.
Limited Crop Variety:Not all plants are suited to hydroponic cultivation. Some crops, particularly those that require large amounts of space or have deep rooting systems, may not be as well-suited to hydroponic methods as they are to traditional soil cultivation.

Setting Up Hydroponics in a Greenhouse

Setting up a hydroponic greenhouse involves several steps, from planning and design to selecting the right hydroponic system and plants. Here’s a comprehensive guide to get you started:

1. Planning and Design

  • Location: Choose a location with sufficient sunlight, protected from extreme weather. East-West orientation is ideal for maximizing light exposure.
  • Size and Layout: Determine the size based on your production goals. Consider space for walking, storage, and possibly expanding in the future.
  • Greenhouse Type: Decide on the type of greenhouse (e.g., hoop house, gothic, or gutter-connected) based on your budget, climate, and space.

2. Selecting a Hydroponic System

There are various hydroponic systems, including NFT (Nutrient Film Technique), DWC (Deep Water Culture), Ebb and Flow, and Aeroponics. Consider factors like plant type, budget, and your experience level. For beginners, DWC or NFT might be easier to manage.

3. Climate Control

  • Ventilation: Install vents or fans to regulate temperature and humidity.
  • Heating and Cooling: Depending on your climate, you may need heaters for winter and shading or evaporative coolers for summer.
  • Lighting: If your location has limited sunlight, especially in winter, consider supplemental LED grow lights.

4. Water and Nutrient Delivery System

  • Water Supply: Ensure you have access to a clean water source. Install a filtration system if necessary.
  • Nutrient Solution: Set up tanks or reservoirs for your nutrient solution. Learn how to mix and maintain the correct nutrient levels and pH for your plants.

5. Plant Selection

Select plants that suit hydroponic systems and your climate well. Leafy greens, herbs, and strawberries are good choices for beginners.

Here are some of the plants that are best suited for hydroponic gardening.

6. Monitoring and Maintenance

  • System Checks: Regularly check your hydroponic system for leaks, clogs, or malfunctions.
  • Water and Nutrient Levels: Monitor and adjust the nutrient solution strength (EC/ppm) and pH levels.
  • Plant Health: Keep an eye on your plants for signs of nutrient deficiencies, pests, or diseases.

7. Automation

Consider automating aspects of your hydroponic greenhouse, such as watering, lighting, and climate control, to save time and improve efficiency.
