How to Use Hydroponics in a Greenhouse: A Step-by-Step Guide

Hydroponics has revolutionized gardening by growing plants without soil, making it a perfect match for greenhouses. 

When paired, they create an efficient, sustainable environment for growing high-quality crops year-round. 

Let us walk you through how to make the most of this setup and why your greenhouse might be the perfect home for hydroponic gardening.

What is Hydroponics, and Why Pair It with a Greenhouse?

Hydroponics is a growing method where plants absorb nutrients directly from a water-based solution, skipping soil entirely. This process enables faster growth and higher yields using less water than traditional farming.

When integrated into a greenhouse, hydroponics becomes even more powerful. 

Greenhouses protect crops from harsh weather and pests while maintaining the ideal temperature and humidity for growth.

Together, these systems allow you to grow vibrant, healthy plants year-round with fewer resources.

Hydroponic gardening paired with a greenhouse ensures year-round growth and resource efficiency.

Choosing the Right Greenhouse for Hydroponics

Not all greenhouses are created equal. Select a structure designed for durability and controlled environments to maximize your hydroponic potential. Here are some features to consider:

  • Light Transmission: Look for materials that let in ample natural light while protecting plants from harmful UV rays. Greenhouses like the Sungrow Urban provide superior light diffusion, ensuring plants receive even illumination throughout the day.
  • Ventilation: Proper airflow helps regulate temperature and prevent mold. The Sigma 20 offers excellent ventilation options, including adjustable windows and vents, making it ideal for hydroponic gardening.
  • Strength and Durability: Ensure the frame can withstand weather challenges like heavy snow or strong winds. All of our Sungrow models have a heavy-duty galvanized steel frame and our Sigma robust design makes them perfect for environments with varying climate conditions.

Key Components of a Hydroponic Greenhouse

Setting up a hydroponic greenhouse involves combining the right equipment with effective planning. Here are the essentials you’ll need:

  • Nutrient Delivery System: Supplies plants with the perfect balance of nutrients. Regularly check and adjust the nutrient levels to match the specific needs of your crops for optimal growth.
  • Water Reservoirs: Store and circulate nutrient-rich water for continuous plant feeding. Ensure reservoirs are clean and contaminant-free to prevent algae growth and maintain water quality.
  • Lighting: Use natural sunlight when possible, supplemented with energy-efficient LED grow lights. Position lights at the correct height and intensity to avoid overexposure or insufficient illumination.
  • Climate Control: Manage temperature, humidity, and airflow to mimic perfect growing conditions. Use sensors to monitor environmental factors and adjust systems automatically for consistent results.

Automating these components with timers and sensors can save time and make greenhouse management easier.

How to Set Up Your Hydroponic Greenhouse

Ready to get started? Setting up your greenhouse for hydroponics is simpler. Follow these steps:

Setting up your greenhouse for hydroponics requires careful preparation to ensure an efficient and productive growing space. Let’s break it down into manageable steps.

1. Prepare the Greenhouse

Before introducing your hydroponic system, it's essential to clean and sanitize the entire greenhouse. 

  • Remove any debris, dirt, or remnants from previous planting cycles, as these can harbor pests or diseases. 
  • Wipe down surfaces with a mild disinfectant to eliminate any lingering contaminants.
  • A clean environment ensures your plants grow in a pest-free space, reducing potential issues that could harm your crops later.

2. Install Equipment

Setting up your hydroponic system involves installing the key components supporting your plants. 

  • Begin with your nutrient delivery system, ensuring it is securely connected and functioning. 
  • Position water reservoirs where they are accessible for refilling and maintenance.
  • Add lighting if needed, focusing on LED grow lights for energy efficiency. 
  • Arrange all equipment to ensure easy access for monitoring and adjustments.

Hydroponic towers are great to save space and grow vertically.

3. Ensure Proper Ventilation

Airflow is critical for preventing overheating and maintaining optimal growing conditions. 

  • Install fans to promote air circulation and avoid stagnant pockets that encourage mold or disease. 
  • Vents are used to manage temperature, especially during warmer months, and to keep the greenhouse comfortable for plants.

Effective ventilation also helps regulate humidity levels, reducing stress on your crops and ensuring steady growth.

4. Test Your System

Before introducing plants, run a trial to ensure that all components of your hydroponic setup are functioning seamlessly.

Check that the nutrient delivery system operates without leaks, water reservoirs are cycling correctly, and lighting is effectively positioned.

Start small if you’re new to hydroponics—a single tray of leafy greens is a great way to learn the system while enjoying fresh, home-grown produce.

Best Crops for Hydroponic Greenhouses

Certain crops thrive in hydroponic greenhouses, offering quick growth and high yields. Here are some top recommendations:

For Beginners:

  • Leafy greens: Lettuce, spinach, kale.
  • Herbs: Basil, mint, parsley.

For Advanced Growers:

  • Tomatoes.
  • Strawberries.
  • Peppers.

These crops are well-suited for hydroponic systems and offer reliable results. Starting with easier plants like lettuce or herbs can help you gain confidence before moving on to more complex crops.

Green vegetables like cucumbers or peppers are perfect starter crops for hydroponic greenhouses.
