PAR Meter VDL

Par Meter Meter for light measurement in indoor crops

The Par Meter VDL Meter quantifies the photosynthetically active photon flux (PPFD) with a range of 0–3999 μmol/m²/s, offering a direct window into the light energy that plants actually use.

The 400–700 nm band corresponds to the PAR spectrum, and the correlation between absorbed photons and photosynthetic rate allows you to fine-tune luminaire distance, photoperiod times, and canopy distribution. The dedicated sensor, attached to the main unit, delivers repeatability ±1 μmol/m²/s and a resolution of 0.1 μmol/m²/s in low readings, facilitating fine decisions in propagation, growth, and flowering.

Manufactured for daily work, it operates between 0–50 °C, with operating and storage humidity without condensation.

Powered by 2 AAA batteries, it avoids dependence on the power grid in hallways or shelves; the set remains lightweight (approx. 115 g without batteries) and comfortable dimensions: 115 × 60 × 24 mm for the main unit and 80 × 45.6 × 26 mm for the sensor.

In installations with bars and panels of LED grow lights, the meter helps detect shadow areas, confirm PPFD uniformity, and check losses due to height or reflector tilt.

Compatible with grid data collection methodologies, it facilitates PPFD maps to estimate averages, minimums, and uniformity, supporting decisions on plant density, training, and pot rotation.

Within the Hydroponics Blanes catalog, a trusted Grow Shop and a benchmark as a Grow Shop in Spain, this device integrates with controllers, timers, and electrical accessories for indoor, with discreet shipping and technical support to integrate measurements into quality routines.

Indoor growing Par Meter VDL Meter

In professional indoor growing, knowing the real PPFD on the canopy surface avoids estimates based solely on nominal power. The Par Meter VDL Meter allows you to adjust luminaire height, balance sides, validate overlaps, and calculate approximate DLI (Daily Light Integral). The result: homogeneous canopies, less occurrence of larfy flowers, and better use of invested watts.

What is the Par Meter VDL Meter for?

• Optimize intensity in each phase of cannabis cultivation by measuring PPFD where the leaves work.
• Design light maps to detect cold spots and adjust panel or bar distribution.
• Calculate DLI from PPFD and photoperiod to maintain constant light targets.
• Compare equipment and reflect real differences between technologies and heights.
• Audit maintenance after cleaning reflectors or changes in electrical configuration.

Instrumentation brings rigor to daily decisions. The Par Meter VDL Meter enables quick verification routines before introducing new genetics or relocating plants. With 120° light distribution, the sensor captures useful variations to correct tilts, orient side bars, and adjust distances with quantitative criteria. The stable reading favors repeatability between measurements, something key when documenting batches and evaluating results of changes in LED grow lights or ventilation.

How is the Par Meter VDL Meter used?

• Power on: insert 2 AAA batteries and activate the unit. Wait a few seconds for stabilization.
• Grid protocol: divide the area into a grid and record PPFD at each point at the same canopy height.
• Adjustments: vary luminaire height/tilt and repeat measurements until uniformity and target PPFD per phase are achieved.
• DLI calculation: approximate DLI = average PPFD × 0.0036 × hours of light (result in mol/m²/day).
• Best practices: avoid body shadows over the sensor, clean the optical dome, and record temperature and humidity to contextualize data.
