Treegers PAR Quantum Meter – PPFD Meter 400-700 nm with Remote Sensor

Frequently asked questions

• What does the Treegers PAR Quantum Meter measure?

  It measures PPFD, that is, the micromoles of photons that actually reach the plant, within the PAR range of 400 to 700 nm. The reading is expressed in micromoles per square meter per second, the value that truly determines the grow's yield.

• Why measure PPFD instead of lux?

  A lux meter measures what the human eye sees, not what the plant uses. PPFD is what lets you know if the light fixture is at the correct height, whether the light spread is even, and whether the edges of the grow receive enough light.

• What is the advantage of the remote sensor?

  The sensor is connected to the display by a cable, so you can place it at canopy height while comfortably reading the value. Without a remote sensor, the meter's body and your own hand cast a shadow over the measurement and skew the reading.

• What use is it for in the day-to-day of my grow?

  It lets you check whether the light fixture is at the right height, whether the light spreads evenly over the table or tent, and whether the corners receive enough intensity. With that data you can adjust the setup to get the maximum yield from your plants.

• Are there any accessories available for it?

  Yes, there's an optional Treegers extension wand available, which lets you take the sensor to distant points without casting a shadow. Keep in mind that the meter's published weight is an estimate.

• When will I receive the meter if I order it today?

  Orders ship within 24/72 hours, and you have easy returns within 15 days if you're not satisfied. You can pay by card, Bizum, PayPal, or split the payment securely with Klarna or ViaBill.
