Thank you to Chris Madsen @ Apogee Instruments for sending us an actual Quantum PAR meter. This will let students design better lighting arrays with increased efficiency! We mailed it to our latest outpost, in Alaska, where power costs US$ 0.50.kWh.
Mars Hydro sent us a Mars Reflector 240W . 99 watt draw from the wall, and lots of individual LED with an output of 650 to 66- nanometers. This is important. Why? Our Apogee Original Quantum PAR meter measures photons in the range of 410 to 655 nanometers. This means that our cool new meter doesn't measure the photons our cool new light produces!
We knew this. Apogee upgraded a few years ago to a sensor that measures longer (up to 700 nanometers) wavelength light.
The point of the Watney Module is to grow food with whatever lights and soil you can scrounge up. Duct tape and aluminum foil make cheap reflectors.
