Not enough to understand the PAD light factors. Is that how you determine the amount of infrared light to give for the Pfr to convert to Pr? It gets confusing because people use different bulbs for different spectrums and I want to do it strictly LED and I don't know what ratios/wattages I need to use for optimal plant growth. You guys have more experience than I do so I was hoping you guys could help me shorten the experimental stages of this and give me your recommendations.
