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 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?
