In a grow tent, we used the scientific research-grade optical radiation standard test instrument of Li-Cor company in America to carry out practical tests. The data showed that the distance from the plant to the grow light's luminous surface was inversely proportional to the size of PPFD, i.e. the longer the distance is, the smaller the PPFD will be. If the distance between the plant and the lamp reaches 24", the PPFD maintenance rate will be reduced to about 50%, which means that about 50% of the light energy is lost. In other words, the utilization rate of the grow light is only 50%. If the distance is longer, the utilization rate of the lamp will be lower. It should be noted that if there is no reflective film in the surrounding environment of plant factories and greenhouses, PPFD will decline faster and the utilization rate will be lower. Therefore, the best range for the PPFD is between 5 to 12. Based on the above tests, it is not difficult to see that the distance between the plant and the luminous surface of the lamp is between 5 and 12 inches, which is the best PPFD acquisition range.
Frequently Asked Questions (FAQ)
Q1: What makes the SPD FOLDING PRO3 unique compared to traditional grow lights?
The SPD FOLDING PRO3 is a third-generation foldable LED grow light featuring a PPE3.0 energy efficiency rating. It offers a comprehensive light profile including a full spectrum plus specialized UVA, UVB, and UVC outputs, alongside a user-friendly power supply maintenance design.
Q2: How does the light manage heat dissipation?
It utilizes an advanced top passive heat dissipation design. This structure ensures the light operates at an optimal temperature for plant growth without requiring active cooling fans, contributing to high luminous efficiency and silent operation.
Q3: What is the recommended mounting height for optimal plant growth?
The recommended mounting height above the plant canopy is between 5 to 12 inches (127-305mm). Tests show this range provides the most efficient PPFD acquisition, preventing excessive light loss.
Q4: How does distance affect the PPFD (Photosynthetic Photon Flux Density)?
PPFD is inversely proportional to distance. While the maintenance rate is 100% at 6 inches, it drops to approximately 50% at 24 inches, meaning half of the light energy is lost if the light is hung too high.
Q5: What are the recommended environmental settings for using this system?
For optimal results, maintain daytime temperatures of 22-28°C (Night: 20-22°C), a CO² concentration of 1200 to 1500 ppm, and a VPD of 1.0-1.49 kPa. Relative humidity should be adjusted by stage: 75-80% for leaf stage, 60-70% for pre-flowering, and 50-55% for late flowering.
Q6: Can the spectrum and power output be controlled dynamically?
Yes. When configured with our optional DALI control system, you can realize spectrum switching, control power output from 0-100% across four channels, set scenario modes, program sunrise/sunset intervals, and enable automatic high-temperature safety dimming.
