started grow question 5y ago
Currently running a 400w HPS lamp. Would there be any significant benefit in adding in a 100w LED board on purple or blurple?

No. Just a waste of electricity. Your 400 watt HPS will be far superior and also be completely adequate.

raise lights during stretch?
Should I raise the lights during flower stretch to maintain the same distance from light source to canopy? I notice that my plants continue to get taller than most. I know the stretch is natural, but I'm wondering if constantly raising the lights with growth is the right approach

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?
