Assimilation Lighting for Greenhouses in the USA

Assimilation lighting refers to artificial grow lights used in greenhouses to support plant photosynthesis. VB is specialized in assimilation lighting for greenhouses.

Consistent light is essential for plant growth, but in many regions of the United States, natural sunlight alone is not enough for year-round production. Assimilation lighting provides artificial light that stimulates photosynthesis, ensuring plants can convert CO₂ and water into sugars that drive growth.

VB designs and installs advanced assimilation lighting systems for commercial greenhouses, helping U.S. growers optimize yield and product quality in crops like lettuce, tomatoes, peppers, and cannabis.

What Is assimilation lighting?

Assimilation lighting refers to artificial grow lights used in greenhouses to support plant photosynthesis. When sunlight is insufficient, such as during winter or in northern states, lamps provide the necessary light spectrum for healthy growth.

Serving USA growers

Besides assimilation lighting, we help growers with the most advanced commercial greenhouse solutions in the world. Check out all of our commercial services below to see how we can build your greenhouse into one of the best in the market.

How does assimilation lighting work?

By supplying crops with the right light intensity and spectrum, assimilation lighting ensures that plants can continuously perform photosynthesis. This results in:

- Faster growth cycles
- Higher yields per square foot
- More uniform product quality

In practice, growers activate assimilation lights when solar radiation levels are too low, creating optimal growing conditions regardless of weather or season.

1. High-pressure sodium (HPS)

Traditionally the most widely used greenhouse lighting.

- Pros: Proven technology, strong light output.

- Cons: High energy consumption, significant heat emission, less efficient spectrum.

2. LED lighting

The current and future standard in greenhouse horticulture.

- Pros: Energy-efficient, minimal heat emission, ability to fine-tune light spectrum (e.g., red, blue, white).

- Cons: Higher upfront investment compared to HPS.

3. Water-cooled LED lighting

The latest innovation in assimilation lighting, already used in VB projects like Little Leaf Farms.

- Pros: Compact design, optimal LED performance due to cooling, higher operating power without reducing lifespan, improved heat management.

- Energy savings:
-- 40–60% less electricity compared to HPS for the same usable light.
-- Similar direct electricity use compared to air-cooled LEDs, but greater efficiency in climate control since less energy is needed for cooling. Heat can also be captured and reused.

Suitable crops for assimilation lighting

Assimilation lighting is beneficial for a wide range of crops, including:

- Leafy greens (e.g., lettuce), already proven in U.S. projects like Little Leaf Farms.

- Fruit vegetables (e.g., tomatoes, peppers, cucumbers).

- Cannabis, where precise light control is essential for growth and quality.

Assimilation lighting FAQ's

What is the best lighting system for a greenhouse?

The best lighting system depends on your crop type, energy strategy, and production goals. VB designs custom assimilation lighting systems using LED and water-cooled LED technologies. While HPS lighting remains a proven solution, modern LED and water-cooled LED systems offer higher efficiency, lower heat emission, and better light spectrum control, helping growers achieve consistent, high-quality yields with reduced energy use.

Is assimilation lighting sustainable?

Yes. Water-cooled LED lighting is significantly more sustainable than HPS systems and provides better climate efficiency than air-cooled LEDs. By reducing energy use and improving heat recovery, VB’s systems help U.S. growers cut operational costs while contributing to the energy transition.

What is assimilation lighting?

Assimilation lighting is artificial lighting used in greenhouses to support plant photosynthesis when natural sunlight is insufficient. These grow lights provide the right spectrum and intensity of light so that plants can convert CO₂ and water into sugars, driving growth and productivity. VB’s assimilation lighting systems are designed to ensure uniform light distribution and optimal crop development year-round.

What is better for growing, LED or HPS?

LED lighting is the current and future standard for greenhouse cultivation. It offers greater energy efficiency, minimal heat output, and the ability to fine-tune light spectra for specific crops. HPS lighting, on the other hand, delivers strong light output and proven reliability but consumes more energy. Many growers now transition to or combine LED and HPS systems. VB helps determine the right balance for your greenhouse to optimize growth and operational efficiency.

What kind of light is needed for photosynthesis?

Plants mainly absorb red and blue light during photosynthesis. VB’s LED and water-cooled LED systems are engineered to deliver these key wavelengths in precise ratios, ensuring plants receive the optimal light for energy conversion and healthy growth, regardless of season or sunlight levels.

What is the best lighting for plants?

The best lighting supports continuous photosynthesis, efficient energy use, and stable crop quality. VB’s advanced assimilation lighting systems combine state-of-the-art LED and HPS technology to deliver optimal light intensity, spectrum, and climate integration. With innovations like water-cooled LEDs, growers benefit from higher performance, lower cooling demand, and improved sustainability.
