First time grower here. Can you adjust the light based solely on the Lux meter? Between 60,000-85,000 is supposedly ideal for flower. however these numbers based fr M my meter brings my 400watt HPS within 6-8 inches from my plant. I use the hand under the light method and it's quite warm but bareable. Or do I also need a par reading or just stick to the 12-24 inches. Thanks for any responses.
