Grow Light Physics: Coverage Area & Running Arrays with the Mars Hydro SP-3000

In this video, I test one and two of the new Mars-Hydro SP-3000s in different coverage areas. I use 5 different PAR tests to explain and explore some of the key aspects of Grow Light Physics. Check out the 4x2 and 5x2 PAR tests with one SP-3000 and then the 4x4, 5x4, and 5x5 PAR tests with two! See below for scene list and links to specific scenes in this video. Be sure to also see My PAR Test and Review Video with the SP-3000:    • Mars Hydro SP 3000 PAR Test and Review   The New Mars SP-3000 is a really impressive fixture! If you want to see what it can do – I will show you! If you want one or two in your own grow space – I don’t blame you!

The physics that I cover is helpful to understand, whether you plan to run the SP-3000 or any other fixture. Don’t be intimidated! I hope to make the science behind grow lights understandable to all growers. I explain all the key metrics and show how we use them to test and evaluate grow lights. I hope that all growers will find the video interesting, regardless of how much experience you have with grow light physics! I hope it really helps to clarify the way that light works in a grow space. This Video is Part of the Coco for Cannabis Grow Light Guide. Check out all of our Articles, Calculators, and Test Reports!
