LED vs HPS vs Plasma vs Fluorescent

Many grow lights boast to be the best, with differing power ratings and light spectra complicating the choice. To help you understand how plants absorb artificial light and how grow lights produce photosynthetically active radiation (PAR), we have prepared the following infographic which compares 4 of the most popular types of grow light: LED, HPS (High-Pressure Sodium), Fluorescent and Plasma.

This infographic will show the differences –
