Field notes
The homepage organizes practical references around plant-light measurement, including comparisons with an Apogee MQ-500, inexpensive PAR meters, and lux meters. Its plant-light hub lists PPFD and DLI ranges for tomatoes, leafy greens, and succulents, alongside explainers for PAR, PPFD, and DLI. The device is listed with a two-year warranty and US-based email support; its accuracy comparison is a homepage claim, not a documented test in the supplied evidence.
