Infrared light is part of the electromagnetic spectrum. Technically, it is outside the range of light visible to the unaided human eye. However, infrared waves affect how plants grow.Continue reading The benefits of infrared for plant growth
LED grow lights are sometimes compared by looking at what has been called, true wattage, actual watts or even draw from the wall. This post looks at what these terms are and why they are misleading when comparing LED grow lights. This post is adapted from Feed The Seeds.Continue reading True Wattage or Actual Watts
The rapid pace with which technology moves have not left any industry untouched. The same holds true for grow lights. Grow lights have evolved from high intensity discharge (HID) to light emitting diode (LED). A number of new developments have taken place within LED grow lights over the years. Two of these developments are Quantum Boards and chip on boards (COBs).Continue reading Quantum Board and Chip On Board
The topic of a previous post was Photosynthetic Active Radiation (PAR) and Photosynthetic Photon Flux Density (PPFD). PAR is the band of wavelengths between 400 nm and 700 nm. PPFD is a measure of the photons hitting the plant. This post will focus on another important measure for deciding on a grow light, grow light efficiency.Continue reading Grow light efficiency
The previous post offered an introduction to PAR and PPFD. The question is how much is enough light and when is it too much. Supplying your plant canopy with an even and adequate amount of usable light is vital, but supplying your plants with more than they need can be a waste of energy and money. This can also lead to negative impacts on your plants.Continue reading How much light do I need?
